A CAD Dinosaur’s Journey, Part 11: We’ve Come A Long Way

April 7, 2015 Leave a comment

Editor’s Note: Welcome to Cadalyst’s blog series by Patrick Hughes, A CAD Dinosaur’s Journey into Modern Times.” In this three-month series, Hughes chronicles his transition from AutoCAD R14 to v2015 and from an outdated PC to a state-of-the-art professional workstation. Follow along and enjoy!

Go Big or Go HomeHardware Hero

Even dinosaurs need to upgrade their computers once in a while. When I started my business in 1991, I chose to buy the most powerful, yet affordable desktop computer possible. Shopping around the local computer stores I settled on a gleaming Intel 486 equipped with a 17” color monitor. It’s almost embarrassing to remember that the price tag was nearly $4,000 back then, but this Dino was ready to work on CAD with the best of them.

Every 4 years or so, hardware technology growth justified an upgrade. Along with the hardware, now and then I also updated my software, that is until I chose to stick with AutoCAD Release 14 for an extended period. In hindsight, that may not have been one of my more astute decisions.

But now with AutoCAD 2015 running at my claw tips on a powerful workstation awarded to me for winning the Cadalyst video contest, this T-Rex is getting all he could wish for.

Powered by an Intel Xeon six-core processor and 32 GB of memory, this workhorse has not left me wanting. Coupled with a 3 GB NVIDIA Quadro K4000, I added a second 23” monitor (which is how I keep my many AutoCAD tool palettes and windows open). I haven’t had any performance issues to speak of. The only sound this machine makes is a pleasing whoosh of the fan on start up. The rest of the day this old Dino can concentrate on my design work without any computer noise in the background.

Tireless Tools

In the right-hand screenshot below you’ll see the Autodesk SEEK Design Center, a new tool I now enjoy. Design Center has been around awhile and you are probably familiar with it. I find it not only useful to insert content from my parts library, but I can also insert blocks from other drawings without opening them. A right-click on a block in a drawing gives you options to insert and redefine the blocks, open in the block editor, or create a Tool Palette. Once created, you can drag and drop additional blocks into the palette. Rawrrr!

AutoCAD SEEK Design Center

AutoCAD’s SEEK Design Center (right) offers tools that let you import objects and more into a current drawing (left).

Blocks are not the only objects that you can easily import from existing drawings, there is a whole slew of items ranging from Textstyles to Layouts, Layers, or Dimstyles to name a few. I mostly use it for blocks because my text styles are already set in my templates.

In an earlier article I mentioned the calculator that you also see in the screen capture. I find it especially useful to avoid errors in numeric entry from calculations. I’m a bit of a stickler for precision and often carry out decimals to 6 digits. The calculator lets me easily paste the calculated value after making the calculation. Any errant keystroke when dyslexia strikes is no longer a worry, well, as long as I don’t enter things wrong in the calculator.

You might also notice the status bar includes a bit of custom diesel code displaying a few items that I long ago decided were valuable. I appreciate that AutoCAD has kept so much of its legacy programmability. But, with that, you can also see that I’m still not using some of the newer tools such as dynamic input and other aids. I keep experimenting with new ones, but many times my old Dino ways seem to get the better of me.

Rawrrr!

In closing, I doubt this constant progression of more powerful computing will end. There are times when you must update and when you do, you should reach for the stars and equip yourself with something that will not just do an adequate job now but will handle future demands as well. How about that? Here’s an old dinosaur offering up advice about planning for the future — what has this world come to?

Expert Interview with Viktor Nordstrom of CL3VER

April 2, 2015 Leave a comment

Viktor Nordstrom understands that the future of CAD exists on the cloud. His company, CL3VER, provides a cloud-based platform for interactive 3D presentations for the web and mobile devices to help AEC and manufacturing professionals to engage customers and stakeholders. CL3VER 3.0, released on March 11, was presented at the GPU Technology Conference together with the integration of CL3VER with Lightworks’ iray+ photorealistic rendering solution that enables users to explore a CL3VER presentation via a web browser and generate a photorealistic rendered image of a specific point of view using iray.

In this interview, Nordstrom discusses the future of CAD and how it is changing along with technology.

In what ways does a cloud-based platform enhance the CAD process?

A cloud-based platform enhances the CAD process by making the time to market products and projects faster, thanks to the possibility of accessing information in real-time from any location around the globe and at any time. The cloud also provides infinite computer power available on an “on-demand basis,” thereby cutting costs traditionally associated with the requirements for expensive hardware and software maintenance.

How do you bring CAD to life on all devices?

The CL3VER proprietary 3D engine makes use of HTML5 and WebGL technology to enable interactive 3D visualization on any device without the need to install any plugin. In addition, a native iOS App provides an immersive experience on iPad and iPhone in high definition. During the next months, we will also improve the current offline viewing system.

How does CL3VER democratize the creation of real-time 3D?

The CL3VER editor interface allows a user to add interactivity to a 3D scene without the need for programming, making real-time 3D accessible to any 3D designer who doesn’t have specific programming skills. The content created is then distributed via the web and made accessible from any device.

CL3VER is headquartered in Barcelona, Spain, and has offices in Palo Alto, California. Do you see a difference in CAD use or experiences between the United States and Europe?

BIM software adoption and penetration in any country is influenced by several factors such as the country’s laws, the industry technology trends and the industry competition, to name a few. In this scenario, we see that in North America, the use of 3D in the CAD industry is widely adopted when compared with Europe. As a matter of fact, that makes U.S. users more skilled and experienced.

Can you comment on the role of CAD workstations in the 3D workflow?

Workstations normally have 2 multicore processors (36 threads, for example) for rendering outputs. The best experience for real-time 3D environments is based on the GPU rather than the processors, meaning the more powerful GPU that is installed in a workstation (more RAM or cores), the better the viewing and working experience will be.

CL3VER does not require a high performing dedicated GPU for its standard use; an integrated graphics card is enough. For professional use, having an AMD or NVIDIA dedicated graphics card brings the production workflow and the viewing experience to a higher level.

Where do you see CL3VER going in three to five years?

We see in the 3D visualization industry a clear trend for real-time solutions. Especially in the AEC and manufacturing industries, the way a project, product or solution is presented is a key element of differentiation that directly affects sales revenues and competitiveness. Top architecture, engineering and manufacturing firms are already using real-time techniques, and we are seeing a great acceptance of CL3VER for its unique fast workflow to produce interactive 3D presentations for any device.

Based on those facts, we see CL3VER in three years from now to be the leading platform for architects, engineers, manufacturers, and any 3D professional to communicate their designs. The platform will allow a super fast production workflow of browser based real-time interactive 3D with a photorealistic quality that runs fast on any device.

A CAD Dinosaur’s Journey, Part 10: There’s An Array of Hope!

Editor’s Note: Welcome to Cadalyst’s blog series by Patrick Hughes, A CAD Dinosaur’s Journey into Modern Times.” In this three-month series, Hughes chronicles his transition from AutoCAD R14 to v2015 and from an outdated PC to a state-of-the-art professional workstation. Follow along and enjoy!

AutoCAD ArraysAs I continue my quest to conquer AutoCAD 2015 and become a thoroughly modern Dinosaur, onto the scene comes AutoCAD 2016. I must leave its study and review to more capable AutoCAD experts, of which there are many. As it is, my tiny arms are full at the moment and I’m having too much fun with AutoCAD 2015.

I am amazed that I can use these new features as I learn them, including commands that I’ve used before somewhat infrequently. For example, I was able to put the Array command (new in AutoCAD 2012) to good use on a current project.

I’ve used the polar array, so I’m familiar with its associative capabilities. However, I’ve only adjusted the number of items or modified a bolt circle diameter. After I played around with some of the other adjustments, I realized that it is a powerful tool.

While designing a small machine for a client, one of the components was a good candidate to have multiple pieces cut from a sheet of insulating millboard using a water jet. After researching a supplier, I found stock that measured 39″ square. After arranging a simple nesting pattern, I created my rectangular array. In no time, I laid out an array of 6 rows and 5 columns for a count of 30 items. Looking at the array I realized there was plenty of stock remaining that could be put to good use.

As I scanned the ribbon (which conveniently pops into contextual view after selecting the array), my tiny Dino eyes noticed the Edit Source and the Replace Item buttons. Well, that looked interesting.

AutoCAD 2015 Ribbon

I quickly rearranged my part geometry, creating a slightly different nesting pattern of the part and then clicked Replace Item. It prompted me to select an item to replace, and voilà! Because the original array was formed with the two nested items, I continued to select the other array elements. By picking an arrowed grip, I easily added an additional column and in short order my new array updated. Plus, my part count was increased to 36 items.

Arrays in AutoCAD 2015

After my update, I saw that the overall height and width slightly exceeded the stock size. I knew that a small reduction in the part geometry wouldn’t hurt the part function, so I quickly updated the geometry, ran one more Replace Item sequence, and my Dino toothy grin started to make my scaley face ache.

This tool is great. The outer square grip on the top right lets you quickly add rows and columns as you drag it to a new location or the outer arrowed grips provide individual rows or column additions. The inner arrowed grips adjust the column or row spacing. This all happens while you receive instant visual feedback during the grip dragging.

I can see that I’m going to have to come up with an excuse to make more arrays.

Rawrrr!

In closing, adding associative arrays to my repertoire really adds value to the work I produce. Additionally, my customer reaps the benefit, as in this case where the part count goes from 30 to 36 pieces — a 20% higher yield. It’s likely that I would have optimized the nesting to gain the same higher yield, but it would have taken me a lot longer.

A CAD Dinosaur’s Journey, Part 9: Hatching, Layers, and More, Oh My!

March 24, 2015 Leave a comment

Editor’s Note: Welcome to Cadalyst’s blog series by Patrick Hughes, A CAD Dinosaur’s Journey into Modern Times.” In this three-month series, Hughes chronicles his transition from AutoCAD R14 to v2015 and from an outdated PC to a state-of-the-art professional workstation. Follow along and enjoy!

Hatching, Layers, and MoreIt has been quite a while since I’ve done actual work in AutoCAD Release 14. In fact, since I jumped into 2015, I haven’t looked back. For this article I wanted to grab a few screen shots to compare and contrast the two versions. As I opened Release 14, it struck me how quickly it started, but that’s about the only thing I miss. I can live with a longer startup because I’ll typically start AutoCAD and leave it open all day.

Hatch Updates

In Release 14 when you type BHATCH at the command prompt, the following dialog box appears. Once you make your selections and picks, you click on the Preview Hatch button to see the changes.

In the Boundary Hatch dialog box in AutoCAD Release 14, you make your selections and then press Preview to see how it all looks.

In the Boundary Hatch dialog box in AutoCAD Release 14, you make your selections and then press Preview to see how it all looks.

In AutoCAD 2015 when you enter the command, the Ribbon switches to the Hatch Creation tab where you can easily access all of your settings (you can also set HPDLGMODE to 1 to display a dialog box). As you make changes, updates dynamically appear as you make them so there is no need to go back and forth to preview your changes. Rawrrr! This is a definite improvement.

In AutoCAD 2015, updates are made to your hatch patterns as you choose them in the Ribbon (or dialog box).

In AutoCAD 2015, updates are made to your hatch patterns as you choose them in the Ribbon (or dialog box).

But wait, there’s more. In Release 14, once you create your hatch, if and when your underlying geometry changes (you just know it will), you must rebuild your hatch almost from scratch.

So, you think you’re going to grip edit a Release 14 hatch? Nope. Think again, Little Dino.

You cannot grip edit a hatch in AutoCAD Release 14.

You cannot grip edit a hatch in AutoCAD Release 14.

But in AutoCAD 2015, you can.

But in AutoCAD 2015, you can.

What about in an AutoCAD 2015 hatch? Yes, in AutoCAD 2015, you can zoom in to see fine details that can be easily updated by grip editing. Usually hatching updates as you go in AutoCAD 2015, although in this example below, it didn’t. I’ll need to dig deeper to figure out why.

autocad-dinosaur-part9_05

For some reason this hatch didn’t update as I stretched some geometry in AutoCAD 2015 — I’ll need to dig a little deeper to figure out why.

In general, I like that for some modifications I don’t need to recreate the whole hatch. Granted, there may be times when recreating the hatch is the easiest solution if numerous changes are needed.

Oh, before I forget (remember my walnut-sized brain), I also much prefer the more defined solid-filled grips in AutoCAD 2015.

Layer Upon Layer

Layer management has also gone through a great transformation. As I’ve mentioned, I try to keep things simple, but simplicity does have its limitations. In the past, I’ve performed most of my layer operations through the dialog box (or home grown AutoLISP routines) rather than the menu drop down. Here’s the simple Release 14 Layer dialog box:

Release 14's Layer dialog box is fairly simple.

Release 14’s Layer dialog box is fairly simple.

I’ve grown accustomed to keeping the AutoCAD 2015 Layer Properties Manager on screen at all times. It makes quick work out of making adjustments to my layers. Unlike the Release 14 Layers dialog box, AutoCAD 2015 lets you to resize the window.

AutoCAD 2015's Layer Properties dialog box makes it easy to adjust layers.

AutoCAD 2015’s Layer Properties dialog box makes it easy to adjust layers.

More New To This Dinosaur

Oh my! Here’s something new. Transparency — this is handy whenever viewing in Conceptual, my new favorite fancy view style. I noticed under Object Properties (which I also keep on screen) that objects have transparency as well. Normally I set this to BYLAYER, but it’s good to be able to adjust each object independently. Within the Content Manager there is easy access to filtering capabilities which I’ve yet to put to use. I generally use my trusty old AutoLISP routines for filtering, but I can see where I can make good use of these tools, especially when dealing with sub-assemblies.

The Laywalk command (dialog box) has been around since Release 2007, but it’s a new tool to me. This useful tool dynamically displays layers as you select them either individually or as multiples. I’ve used it a number of times and the only drawback with it is that the dialog box must be closed to work with displayed objects. There are numerous new layer tools — I will delve more into them and report back to you once I learn more.

Rawrrr!

In closing, as I work with AutoCAD 2015, I find that I’m able to keep things as simple as I like. However, there are times that when it’s important to make a more professional-looking drawing and it’s good to know I can easily I can do so.

When I first learned to draft on the drawing board as a wee T-Rex, I learned to use lineweights to make the drawing “pop.” Over the years working only on CAD, I’ve let those drafting techniques lapse. It’s time for me to ratchet things up and make my drawings a bit prettier (says the ugliest dinosaur in the room).

Expert Interview with Art Whitton of myCADsite on Continual Education for CAD users

March 21, 2015 Leave a comment

Education isn’t like it used to be, where you would graduate, grab a piece of paper, and dance into a new career. With technology and industries constantly evolving and being updated, education is an ongoing process.

This is true of every technological industry, but especially so for CAD users, with new versions frequently being released. A CAD engineer’s education is never done.

Art Whitton started myCADsite with new CAD users in mind, but it is useful for engineers in every stage of their career. He took a moment to tell us about the beginning of this free tutorial site, the best ways to learn CAD, and some exciting prospects on the horizon.

Can you introduce us to myCadsite? When did you get started? What made you want to start your own business?

myCADsite.com is an AutoCAD tutorial site aimed at new users. It started out when I began a job at a design school and found that they had no lesson plans or other material for me to work with, so I had to write my own. I just started writing one or two a week as needed, and soon I had about twenty lessons on my hands. This was also the time when I was starting to teach myself website design, about 1999.

In the early stages, it wasn’t a business. myCADsite was just a series of tutorials that people might have trouble finding online. It was actually good for getting some job offers, since I had my resume posted on the site.

Over the years, it has evolved to become one of the most popular sites to learn AutoCAD for free. I’ve expanded on the original lessons, added videos and updated the material as new versions of AutoCAD are released. I now have 55 tutorials and 59 videos that will take a user from the very basics of drawing a line to 3D modeling and rendering.

My goal has always been to try to teach the most common tools that drafters will use in their daily tasks. I also try to teach so that each lesson is a natural progression from the previous one.

Who is your main audience, and what are some ways that you fill their particular needs?

My main audience is new users of AutoCAD. These might be students in a related field who need to learn AutoCAD to supplement their skill set, or older people who have hand-drafted for years and need to learn the software. I also hear from a lot of people that just want to learn a new skill to help their chances to get a job and move their career forward.

myCADsite helps people by providing a free course with quality material. Anyone with Internet access can download a demo version of AutoCAD and start the course. My goal is to keep the course free to help the people who can’t afford to go to school to learn the program. I also don’t require registration so that there are no barriers to keep someone from starting the course.

It’s very satisfying to hear from people all over the world who have taken the initiative to learn the software and started a new career path.

I also allow public schools to use the material freely and have licensed the tutorials to several colleges.

Here are some comments about the site.

What are some things you’d say for people learning CAD for the first time? Would you recommend going into this line of work?

I get a lot of emails from people who “want to learn CAD.” Some have very specific reasons; others just feel it’s something they should know. My most common advice is to take it slow and learn the basics thoroughly. Then go back and review them – and then practice them some more.

In the classroom, I saw so many students rush through the first assignments and then start forgetting some of the very basic tools later on. Once users have a solid foundation, it usually sticks with them and makes learning the other topics much easier. I’ll also remind them that they need to focus on speed and accuracy, since no employer wants a slow, mistake-prone CAD user.

When people ask what their job prospects are like, I try to be as honest and blunt as I can. I tell them what I was told back when I was learning at BCIT: “AutoCAD is just a tool.” Most of my instructors repeated this. So I’ll ask people what their background is and how it could be applied to design. I let them know that kids are learning how to use AutoCAD in high school now, so it’s not always a matter of just “learning CAD.” There’s a lot of competition out there.

What about people who have been using CAD software for a while – what are some reasons for them to continue their education? How can the training they receive on myCADsite help their career?

I’ve worked with people that have used CAD for years and find that some them use the same techniques they used when they first learned the software. I’ll go in and review a new version of AutoCAD when it comes out and see what benefits it has for my workflow. One of the things that first interested me in CAD was that there would always be something new to learn.

I hear from a lot of experienced users who have visited myCADsite to brush up on their skills or see what’s new. If they’ve been away from the software for a while, they can quickly get back up to speed and possibly learn some new tools along the way.

Anything that makes a CAD user more productive is good for that person and their employer.

Can you give a brief overview on what you go over in one of your courses? What are the assignments like?

A typical tutorial will start with an overview of what will be taught, and then explains the process step-by-step so that the user can follow along easily. After that, there may be an exercise or two that uses the tools shown in the lesson. Finally, a video is available to visually show how the command or tool works. At the end of the tutorial, the student can take a short four-question quiz to see if they understand the topic.

Not everyone learns the same way, so the explanation, the step-by-step overview and the video can all appeal to different types of students.

Most of the exercises are simple drawings that the student should be able to complete in a short amount of time. By the time students finish the first level, they know most of the common drawing and editing commands. Level Two takes them in a different direction and makes them draw a floor plan. This takes their focus from learning how the tools work to how to apply the tools properly.

With writing the website and designing the CAD courses, you must be very aware of what’s going on in the industry. Have you noticed any developments that are particularly exciting?

I will look around at some articles and still subscribe to a couple of CAD newsletters, but I find that my interest in CAD is making sure that my website’s content is still correct and up to date.

Do you or any of your students use a CAD workstation? If so, which one are you using?

Not really. My last full-time CAD job was drawing as-built survey on location. I usually had an older Dell laptop to work with and it got the job done.

I’ll get emails from students asking what kind of computer they should use, and I’ll usually advise them to try the one they have. Then I’ll send them a link to AutoCAD’s system requirements as a guideline. For many students starting out, the assignments and drawings are small files, so a powerful workstation isn’t needed right away.

Do you have any advice on some specifications to look for if someone is looking to invest in one for the first time?

I’ll usually give people the same advice: “Get the best you can afford.” With RAM and storage space so cheap these days, it’s almost a sin to have a low-end computer. For the past 20 years, I’ve bought bare bones kits and put them together and swapped out parts as they’ve needed upgrades. It’s a great way to learn how they work, and you get the most bang for your buck.

There was a blog post a while back on myCADsite about Harvard scientists using CAD software to make a 3D Rendering of a DNA-RNA molecule. What are some other innovative uses you’ve seen of CAD software being used? What are some other industries that are starting to adopt the software?

When I started working in the industry, I was a little disappointed that all of the cool, cutting-edge things I had learned (this was 1997), like data extraction and 3D modeling, weren’t being used in the jobs that I was getting. I know that’s still the case in many workplaces these days, but for simple designs you just need an accurate 2D drawing.

I see the world adapting to 3D printing, and I think that is an area will explode in the next 10 years. Reading about how NASA emailed a wrench to the International Space Station was exciting news to me.

I love to see how 3D models are used in medical science. 3D printing of body parts and prosthetics will become more commonplace and bring costs down. It’s a very exciting time for science, and seeing how CAD can be implemented will surprise us all.

And it all begins with Tutorial 1-1 and learning the X-Y coordinate system.😉

Expert Interview with Pam Broviak on CAD and Public Works Departments

March 18, 2015 1 comment

Like plenty of other job sectors today, public works departments are being challenged to deliver a wider range of services faster and more efficiently with fewer available dollars and staff, says Pam Broviak, manager of Public Works Group, a portal for public works professionals. “This is why we are most interested in headlines and issues related to anything that offers potential to help us perform within these parameters,” she adds.

These include innovations like driverless vehicles; tools that allow them to better capture, analyze and maintain data and information such as GIS/CAD/LIDAR and other 3D technologies; and hardware that leverages these tools such as headsets and smart screens, phones, and tablets and even smart construction equipment.

Broviak recently checked in with Cadalyst to share more about the technology her audience is most excited about, as well as developments they hope to see in CAD in the coming years. Here’s what she had to say:

Tell us about Public Works Group.

Public Works Group was launched in February 2007 as an online resource for public works professionals because we had started to realize online tools and technology in our field had advanced significantly in a very short amount of time. And we knew this was only the beginning. Today, we face continued and rapid change while still trying to catch up with an aging infrastructure and keep up with a new and dynamic workforce. So we wanted to find a way to explore these tools and help ourselves and others keep up with the changes. And we wanted to figure out how all of this fits into everything else we do.

By creating a group and offering online resources, we were able to begin documenting what we found and offer this information to others in our field. Our focus over the last eight years has been on 3D technologies, social media, e-learning and online education, interactions with and support of industry vendors, and promotion and support of industry organizations and communities.

Who should be following your site?

Primarily anyone working in the engineering and public works field or who work in government or delivery of any public service, including those who are interested in or whose work is related to these fields. Also, people who are interested in 3D technology and social media and who want to learn how to leverage these tools to enhance the delivery of information and services.

What technological innovations do you think your readers are most excited about these days?

While I would again mention the innovations above and specifically point out those in the following list, I would also add that while these might be exciting, we are part of a very conservative field that at times can be slow to change. So most professionals are very cautious about getting too excited about any of these and are not ready to embrace them just yet.

  • The Google car
  • Google Streetview and Google Earth (these have been around a while but are still viewed in the industry as new and amazingly helpful innovations we regularly use and for which we are very thankful to have. One of the biggest reasons they are so beneficial is because they are free to use and save us a lot of time.)
  • Oculus Rift and other headsets
  • Smart phones/tablets and the availability of apps
  • Smart boards
  • Collaborative tools such as Dropbox and Doodle, and even Google apps and other cloud applications
  • GIS, LIDAR, and other spatial technologies and the open data movement
  • 3D printing on a large and small scale
  • 3D Design and Modeling/Visualizations and automated machine guidance (This is a federal initiative, so there are many resources/info on this topic here.)

How is Public Works Group using CAD today?

The Public Works Group is primarily using CAD to develop online resources to use in 3D or virtual settings and in our educational offerings and courses.

What do you think is the future for how public works departments use CAD?

As engineers and public works professionals, we are most familiar right now with CAD and prefer to develop in that environment. So for preparing plans and traditional deliverables, we will most likely continue to work in that environment for some time.

However, as the other tools mentioned above advance, there could be a turning point as we face an increasing need to integrate our plans and designs with those tools. If CAD companies begin to realize the need to and benefit of integrating their technology with these tools, the use of CAD could increase significantly because it would open up new and more advanced uses of the software. But at least one CAD company has indicated to me they are not interested in pursuing this use of their software. So if that is the case, we will eventually end up only being able to use CAD software from companies that have built this integration into their product, or we will have to look to other tools that are usually not thought of in the industry as traditional CAD such as Blender; or do what some companies are doing now and use yet another software service to produce programs to take CAD plans and translate them into something that can be used by these other tools.

What do you think are the must-haves for CAD workstations for those in public works?

Multiple monitors, wireless hardware such as a keyboard and mouse, a computer set up to meet and sustain high-end graphics and CPU demands (as a side note, the most deficient item I’ve seen on this is having a power supply that can’t keep up), and a network designed to deliver, archive, and back up files and software.

What do you think are the biggest frustrations that those in public works have with their current CAD workstations?

  • Single monitors – some organizations do not allow multiple monitors, which can greatly reduce production and performance
  • Not having input on hardware specifications – many organizations do not consult the users before purchasing hardware, so many workstations cannot deliver the graphics and meet the CPU demands. This results in greatly reducing production because the user has to wait a significant amount of time for graphics to load when using CAD or GIS
  • Not taking into account speed of broadband services when working through a network that is located off-site – this also greatly reduces speed of performance
  • Not having an efficient backup and archiving system designed for easy access to users who need to share the files – this can take up a lot of staff time when files cannot easily be found and retrieved or shared

A CAD Dinosaur’s Journey, Part 8: Something Old, Something New

March 17, 2015 2 comments

Editor’s Note: Welcome to Cadalyst’s blog series by Patrick Hughes, A CAD Dinosaur’s Journey into Modern Times.” In this three-month series, Hughes chronicles his transition from AutoCAD R14 to v2015 and from an outdated PC to a state-of-the-art professional workstation. Follow along and enjoy!

Dynamic UCS, Dynamic Input, and Dynamic Blocks At some point, the AutoCAD programmers decided to add dynamic functionality to some AutoCAD features. Dynamic UCS, Dynamic Input, and Dynamic Blocks to name a few! When you typed in DYN at the command prompt, you’d see 13 system variables appear! You would think that the word dynamic would appeal to this dino and, to be honest, it does have a nice ring to it.

While I’m trying to like how these features work, I am struggling with dynamic UCS. I’m still trying to understand how it affects some of my customizations. For instance, one function restricts movement to a specific axis. If I want to move objects only in the Y-axis from picked points, it’s supposed to only move on the Y-axis. Sometimes things go wacky and the objects move unexpectedly and the value that is echoed back to the command line shows X or Z values. Perhaps there are other factors, such as Osnaps affecting it. I suppose that I’ll eventually figure it out, but for now I’ll just think of it as a ghost in the machine.

Lost, But Not Forgotten

An old friend of mine is the Blipmode command. As it is now in AutoCAD 2015, it’s a zombie command — it exists, but it’s not as easy to just turn it on. I dug around and discovered that I could redefine it in my ACADDOC.LSP by adding (command “redefine” “blipmode”) to get it working again. I use the little blips as a visual confirmation for pick points, often as a clue to where on the screen I picked for a selection window. If I mistakenly selected a location, I know not to select the same spot again. Now AutoCAD displays a colored window as you begin your selection, blue for contained selection, green for crossing, and a new cool colored Poly Drag mode. Along with enabling selection preview, these can make it easier to select objects. The blips do still come in handy to see that I correctly picked the endpoint of a line or the quadrant of a circle, etc.

 

T (that’s me) loves blips — they can make it easier to select objects.

Another old friend is the Aerial View command. Not many users were familiar with this little tool and I suspect that’s why it was discontinued. Like Blipmode, you can redefine it, but when I did, the viewer did not display the screen graphics in the viewer window. On the other hand, now that I’ve gotten used to AutoCAD 2015, I don’t miss it like I thought I would. Believe it or not, Release 14 did not let you zoom in and out with the mouse wheel. For the most part, that’s how I’m now navigating large drawings. In fact, you should see how muscular my stubby dino finger is.

Side note: Did you notice that the Explode ribbon icon with a stick of dynamite has been replaced with an image of a broken apart cube. Really? Bring back the dynamite image!

New Awesome Tools

So, enough reminiscing of old dead things, what’s new that’s exciting to this old Dinosaur? For one, the right-click menu that pops up when you select an object. My number one favorite tool is the ability to hide objects (Isolate / Hide Objects) which initiates the Hideobjects command (introduced in AutoCAD 2011). Or, you can select to isolate selected objects. If I need to see hidden objects again, it’s just another right click away. Additionally, there are commands that are available from the menu; a list of recently used commands and input, clipboard functions, filters, properties, a powerful integrated calculator. I find the calculator especially useful.

One of my favorite new tools is the menu that comes up when you right-click on an object.

This little brain of mine gets so easily distracted! I was talking about all things dynamic and I planned on talking about another new-to-me AutoCAD feature, dynamic blocks, and how I plan to put them to use. Alas, my time is running out for now, so I must leave that subject for another date.

Rawrrr!

In closing, old habits can be hard to break away from. Although some may still hold value, I continue to be surprised at how much more efficient the new environment can be. In the past, I’ve always thought that customization was key to delivering greater efficiency, but I’m discovering that AutoCAD 2015 has many of the tools I need right at my fingertips — just the ticket someone with tiny arms!
