How to Catch Design Problems Quicker With Geometric DFX

If DFX sounds like a new product to you, it isn’t. For some time, it has been offered as an add-on product called DFMPro, which has been integrated into a number of high-profile CAD software solutions, including SolidWorks, Creo, and NX. DFX is the stand-alone product now offered by Geometric. While DMFPro works within a specific MCAD software package, DFX works with native models and assemblies in almost all CAD software programs. The cool thing about DFX is how easy it makes finding design flaws in the early design stages, helping to eliminate engineering change orders (ECOs).

What’s Useful About DFX?

ECOs are wasteful and expensive. It is estimated that ECOs are responsible for eating up some 20 to 50 percent of the total cost of designing and producing a product, and about 30 to 50 percent of the cost of engineering and research and development capacities. Some design flaws aren’t evident until much later in the development process, such as when the product hits the production line, during product testing, or when the end customer begins to complain.

DFX helps eliminate this waste of time and resources in a simple, user-friendly way. It automatically recognizes areas of the design that need special attention, such as the placement of holes and bends, how wide ribs and slots are, and the height of bosses. DFX as a stand-alone product can help eliminate cost overruns, and speed the time to market.

DFX combines the in-house knowledge base with industry best practices and automatically applies the design rules with just a few clicks of the mouse. It is also customizable for specific industry needs, as well as particular company or user needs and preferences.

How Does DFX Work?

It isn’t necessary to be an experienced CAD designer to leverage this product. DFX requires only basic CAD software knowledge to operate, such as how to rotate, zoom, etc. It combines a number of knowledge bases, including technical documentation, data from testing and analysis on previous projects, and known ways to improve efficiency and lower costs with designs.

Once the knowledge is added to the system and the program is configured according to needs and preferences, it looks for issues that might be found in production or during product use. This includes identifying issues like mold release when manufacturing plastic parts and pieces, bending issues often seen in sheet metals, and service access problems associated with making parts. It helps users identify design flaws at the earliest possible stage of development, when these issues are quick, easy, and cheap to resolve.

DFX Compatibility

Geometric DFX works in most CAD formats, including:

• SolidWorks
• CATIA
• Creo
• Inventor
• NX
• Solid Edge

It is also compatible with most neutral formats, including:

• IGES
• STEP
• Parasolid

DFX is useful for injection molding, sheet metal, machining, castings, and assembly. A free trial of the product, as well as demos and videos, are available at the Geometric DFMPro website.

Optimizing Your Revit Workstation for Point Clouds

Reality capture is a boom business for the building industry. With roughly 5 million existing commercial buildings in the United States alone, it’s easy to understand why. Laser-scanner-based reality capture is the dominant methodology used today to accurately capture the 3D state of an existing building. However, the typical laser-scan-based point cloud is in the hundreds of millions of 3D points, sometimes even going into the billions of points. With this additional data overhead on top of an already dense Building Information Model, it’s important to optimize your workstation hardware to deliver a productive user experience.

Point Clouds in Autodesk Revit 2013

Finding the Bottleneck

Under the hood, Autodesk Revit utilizes the PCG point cloud engine to rapidly access the 3D points contained in point cloud and retrieve points to be displayed in the current Revit View.  Since the typical point cloud dataset is so large, a workstation’s RAM is insufficient to be used as the means for access by the PCG engine in Revit.  Instead, the disk drive is used for access, while a small amount of System RAM and Video RAM is used for the current Revit View.  Thus, the hard drive is commonly the limiting factor for point cloud performance, rather than system RAM, CPU, or GPU.

Learn the Options

With data access a common limiting factor to the performance of the Revit point cloud experience, let’s discuss the options available to deliver the best experience. There are two primary types that are found today: spinning platter and solid-state drives.

• Spinning platter drives are the traditional hard drive technology, and are found in most computers today, as they deliver the best balance of storage capacity, read/write access speed, and cost.
• Solid-state drives (SSDs) are relatively new technology, contain no moving parts, and are generally much faster at reading and writing data than typical spinning platter drives.

In a structured comparison completed by the Revit product team, we found the following results when comparing typical versions of these Disk Drive types:

Revit Point Cloud Performance Comparison

Reap the Benefits

Based upon this investigation, we would highly recommend that those looking to optimize their Revit workstations for point cloud use install an SSD for at least the local storage of the point cloud data.  While you will also achieve additional benefits from running the entire OS on your SSD, a significant performance boost can be achieved through the retrofit of a ~$200 SSD to an existing workstation.

The Best Hardware Configuration for SolidWorks CAD Software

Optimizing hardware for SolidWorks is essential for getting the most out of this heavy-hitting CAD application, as we’ve discussed on CADspeed previously. So we were thrilled when the SolidWorks forum addressed this very issue recently on their forums.

The key to getting the most out of SolidWorks, or any CAD application for that matter, is ensuring your hardware can handle the workload. Remember that your situation is unique. In simple terms, two users using the same software on the same system may have very different perspectives on their workload efficiency if one is using 3D rendering and the other is not. Consider your needs first and foremost.

On the flip side, if you know you need new hardware, simply buying the most expensive machine may not pay off in the long run either. Think in terms of your productivity while shopping for a new workstation to get the most for your budget, hopefully with a little room to grow for those inevitable upgrades.

That said, here’s a summary of the recommendations straight from SolidWorks themselves.

RAM (Random-Access Memory)

The amount of RAM you need depends less on SolidWorks and more on the number of applications you run at the same time, plus the size and complexity of your SolidWorks parts, assemblies and drawings. SolidWorks recommends you have enough RAM to work with your common applications (i.e., Microsoft Office, email, etc.) and load your SolidWorks documents at the same time.

The recommended RAM for the current SolidWorks versions is 6GB. That should be your starting point. For more information on how much RAM you need, here’s a great resource on the SolidWorks forums.

CPU

Processor speed is another key factor when selecting the right hardware for you. It’s hard to sort through all the different options though, so we recommend testing a system with your actual models. SolidWorks also offers a helpful Performance Test, which offers a standardized test for determining performance of your major system components (i.e., CPU, I/O, video) when working with SolidWorks datasets. Even better, when you complete the SolidWorks Performance Test, you have an option to share your score with others. This gives you, and other community members, a sense of where a system stands relative to others. Nice!

Note that SolidWorks and some of its add-ons (PhotoView 360) have some multithreaded capabilities, so the application can use the second processor or multiple cores. But SolidWorks says that rebuilds are single threaded and therefore rebuilds generally will not be faster with multiple CPUs or cores.

Disk

The size of your hard drive or solid-state drive should be based on the disk space you need. Take a look at all your system’s components: operating system, applications and documents. If you work primarily on a network, your needs may be different than those who primarily use their local drive. Don’t forget to develop a back-up plan for your data, if you don’t already have one. (You do have one, right?)

Graphics Cards

The very nature of CAD software requires a good workstation-level graphics card and driver. You are probably going to need at least a mid-range card, if not a high-end card, depending on the type of CAD work you do. For graphics cards, we recommend starting with the SolidWorks Certified Graphics Cards and System, because SolidWorks has done the testing for you.

Set Up an Online Backup System for Your CAD Data, Part 2 – The Freelancer and the Small Business Owner

So we established that you need an online backup system for your CAD data. So, where do you begin?

For the Freelancer

So maybe you think that you don’t need a dedicated backup routine because you are just doing CAD work on the side. You are the part-time freelancer with only a few jobs on your drive. But data of any kind is important, especially if it belongs to a client. Backing up for the freelancer does not have to be complicated.

Dropbox.com is a freemium service (a service with both free and premium versions) designed to make backing up as easy as saving to a local directory. Just visit Dropbox and register for an account to get 2 GB of free storage in the cloud. Once you are registered, download the Dropbox application for your desktop or mobile and you are set up. The installation will put a nice little “Dropbox” folder icon on your desktop. Treat it like any directory to save files and create sub-directories. The trick is that everything you put in this magical folder gets backed up to the cloud! Your data is instantly saved off-site at Dropbox’s secure data centers and available anywhere you can use a browser!

For the Small Business

So you’ve been working as a freelancer so long that you are now a small business! Maybe you have a few employees and more clients. Your data storage needs are too big for Dropbox so what now? Enter Carbonite.

Carbonite.com is a online backup service designed for heavier lifting than Dropbox. Signing up with the Carbonite service will bring automated backups to your small business. Just like Dropbox, Carbonite will automatically backup your data to off-site servers. However Carbonite service plans allow you to back up data from all of the workstations and servers in your small business! Not only will your data be secure in the Carbonite data centers, it is secure on the way there with end to end encryption.

Do you have a larger business and more intensive data backup needs? Don’t worry, I haven’t forgotten you. Next we’ll talk about enterprise solutions.

Set Up an Online Backup System for Your CAD Data, Part 1

Fire. Hurricane. Theft. Tornado. Grape juice. Electrical surge. Really when you get down to it there is no end to the list of disastrous events that can beginning of the end of your workstation’s hard drive. That may seem pretty obvious, but what may not be as obvious is that there is no end to the dangers that your data must face also! Whether you are a corporate giant or a freelancing CAD professional, the danger is really the same. Any day could be the day that you lose your valuable data!

What can be done to save our precious data from the evils of the world? Should we build hurricane and nuclear proof shelters around our workstations and servers? Should be install wind turbines and storage cells to provide clean, constant electrical currents to our equipment? Should we duct tape our children to cinder blocks whilst they enjoy their afternoon juice box? Well we could do all that or … we could just back our data up.

No Safety in CDs

No I am not referring to that pathetic stack of CDs and DVDs you have haphazardly stacked by your monitor. Half of those things aren’t even labeled! If that is your backup scenario then the things are looking pretty bleak. What would happen if a disaster struck your office and destroyed workstation? If your backups are sitting right next to that workstation, they are gone too! Not much of a system, is it? They probably weren’t up to date anyway.

No, what you need is an off-site backup system. That, of course, is the system where your data is saved securely at a location away from the workstation. This is the only way you can be sure that your data is safe and you can carry on with business in the face of disaster. “Off-site backups” may sound complicated, but they aren’t. In fact there are dozens of services ready to help you get started.

Next, I’ll outline specific services for different types of organizations.

How Advances in Mobility Technology Will Affect the CAD Workplace, Part 2

In my last post, I theorized how advances in mobility technology will affect the CAD workplace. Now, what are these wandering CAD minstrels going to work on? Oh, that is the beauty of it all.

In this vision of the future that I have, mobile CAD applications and platforms will pop up everywhere. Today your CAD workstation weighs about, what … 15 pounds? What if it weighed one pound? What if it weighed less than pound? With current tablet technology, that is precisely what a mobile CAD station weighs! Imagine a future where technology brings us interfaces that are just a screen and no thicker or perhaps screens that fold or roll up for storage.

Think back to your childhood when we all watched the Warner Brothers cartoon that depicted the “House of the Future.” Remember all of those outlandish and whimsical imaginations of the robotic maid and the rehydrated seven-course meal? Use that mindset and imagine a world where your CAD interface isn’t on your tablet or phone. Imagine that is so archaic that it is laughable.

No, the future of mobile CAD is a world with holographic interfaces. It is a world where augmented related toolsets combined with GPS tracking and accelerometers allow us to see the unseen. Architects and planners will be able to visit a bare site and through the window of their “tablet” see the future construction in real space! They will walk around and see if the sink is too far from the kitchen island. If it is, they will use a tactile interface to revise the design and update the server files.

Right Here, Right Now

Would you like to know what the absolutely best thing about my insane vision of the future is? It is here, now. We are walking around in a world of people who are never unplugged. Information is flying at us 24 hours a day, 7 days a week and the little screens in our pockets and bags are lighting up and buzzing. Now that developers have seen the future begun to create software for this mobile tech, we are off and flying!

Maybe the screens aren’t folded and put into back pockets and the interfaces aren’t tactile, holographic systems. Nevertheless, the power to leave your desk behind and get at least some of your work done on the go is here. Now! So upload or email your drawing to your cloud or mobile device. Take your dog to the park and enjoy the breeze while he plays and you review those General Notes. If something needs to be changed, do it there on the bench. Do it today because who can say where technology will let us work on our CAD files in the future.

Build a Network System for CAD Operations, Part 3: Data Vaulting

So far, we’ve discussed the value of building a network system for CAD operations. From an operator perspective, the workstation has the CAD application itself stored locally. But the files should reside on the shared storage device.

The next component of a network system for CAD operations is data vaulting. Data is the core of your business. All of your data — your CAD designs as well as your emails, customer records, documents, invoices — they’re all data you can’t do without. A data disaster can be crippling for a business, and the cost of downtime is typically in tens of thousands of dollars.

Offsite Data Vaulting

The solution is to backup your irreplaceable data from your desktops, laptops and servers with an offsite secure data vaulting service. This service should provide your business with the ability to back up your data offsite, to a dedicated backup server that’s managed 24/7 at a secure datacenter.

Did you know that 43% of U.S. companies experiencing data disasters never re-open, and 29% close within 2 years? The loss of revenue for each hour of downtime varies from industry to industry. Don’t let your company become a statistic.

Why Backup Online

Online backups are the easiest and surest way to protect your data. Backing up to an offsite server ensures that you can recover your data even in case of a physical disaster, theft or loss. Online backups also eliminate many of the error prone steps associated with traditional backup methods like tape. Users can restore ‘point in time’ versions of files without loading tapes one after the other.

With an online backup solution, your data is encrypted and compressed even before it leaves your computers. After the first full backup, only incremental block level changes are sent — optimizing bandwidth & storage usage.

How Offsite Data Vaulting Works

With offsite data vaulting, your IT department installs an agent on each computer (workstation /server) that you wish to protect. After the initial configuration, backups happen automatically and your IT team can monitor and manage the process remotely.

The best data vaulting services will backup your data off-site to the main office and replicate it to another office, giving you redundant backups just in case the worst happens.

Data backup is inexpensive insurance against a business disaster!

Build a Network System for CAD Operations, Part 2: RAID

Our first post introduced the idea of building of a network system for CAD operations. From an operator perspective, the workstation has the CAD application itself stored locally. But the files should reside on the shared storage device.

RAID – Redundant Array of Independent Disks

In general, you want to talk to your IT department about RAID, which stands for Redundant Array of Independent Disks. In essence, the term describes exactly what it is – computer data storage devices that are set up to divide and replicate data among different drives. The drives are separate, but the operating system enables them to function as one disk.

RAID-1 can be used in a workstation.

RAID-1

RAID has many levels. One of the simplest, called RAID-1, creates an exact copy of a set of data on two or more disks. RAID-1 is useful when read performance or reliability is more important than data storage capacity. RAID-1 can be set up on a CAD workstation itself, which is common in high end workstations to ensure their uptime as well.

RAID-5 is just one level of RAID -- there are many configurations available.

RAID-5 and Higher

For comparison, RAID-5 stripes both data and parity information across three or more drives. It exchanges the dedicated parity drive for a distributed parity algorithm, writing data and parity blocks across all the drives in the array. If one drive fails, the duplicated data is still safe on other drives. RAID-1 and RAID-5 are two of the most common levels, but there are many more. Your IT department can help you develop a system that meets your company’s needs.

Taking every precaution is vital because recreating CAD work is hard work. Next, we’ll discuss data vaulting.

Build a Network System for CAD Operations, Part 1: Prevent Catastrophic Failure

A network system in a CAD facility is a vital part of the operations of any CAD production team. The nature of CAD work has value far beyond the price tag of the workstation, software and server. CAD files often have hundreds of man hours wrapped in data files – time and effort that equals money.

From an IT perspective, no CAD operator should have all the work he/she does sitting on a computer. It is essential to make CAD files available as shared files. Often, teams of people work on CAD designs. Plus other people need to review the work. It’s important to have a network that facilitates the review process as well as the data integrity. Updates of CAD software have continually improved the operator’s ability to work as a team. However, a solid network is still an essential part of the CAD production environment.

Don’t Rely on Luck

We had a client with CAD files sitting on his laptop that represented 150 man hours. He had been traveling extensively overseas, and he wasn’t able to back up his computer as normal. The hard drive failed. He was lucky. At great expense, we were able to retrieve most of his data. But besides the hefty bill for recovery, he lost the time involved in retrieving the data, not to mention the mental anguish.

So, given that your CAD files represent a huge chunk of your time and mental energy, how do you prevent catastrophic failure? You make sure you have your files stored in a secure location.

Our next post will explain one way to do that.
