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.
Geometric DFX works in most CAD formats, including:
• Solid Edge
It is also compatible with most neutral formats, including:
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.

Data-sensitive environments are no longer limited to defense agencies, power generation firms and related contractors, but include any enterprise that places a high value on its intellectual property. These environments require specific security precautions to ensure the security and integrity of sensitive and confidential information.
Security breaches can occur when documents are not disposed of properly. This is not only limited to hard copy documents but also electronic data. Unfortunately, simply deleting files isn’t enough. Threats to your data and secure information linger long after you delete a file.
The disk drive that is part of a large format printing device’s controller is used as a temporary repository for spooling and processing data (e.g. copy, scan and print jobs). These drives are susceptible to data remanence – the residual representation of data that remains even after the data is deleted – which can inadvertently make sensitive data available to unauthorized users.
The Importance of Electronic Shredding
Proper disposal of electronic data stored on a large format printer’s disk drive is imperative to preventing inadvertent disclosure of sensitive or confidential information. To prevent this from happening, specific security precautions should be integrated into all network devices.
Purchasing a large format device that is equipped with electronic data shredding (or e-shredding) functionality can help prevent recovery of previously printed, scanned and copied documents. With e-shredding technology, data is overwritten in such a way that makes it impossible to retrieve or reconstruct it. Print, copy and scan jobs sent to a large format print system enabled with this technology are completely overwritten and erased upon completion of the job. This can be particularly useful in decentralized walk-up environments where many different users have unregulated access to the system.
Electronic Shredding Options
Most systems that offer e-shredding functionality allow the administrator to select from a number of overwrite algorithms. Common algorithms used in the United States include:
- Gutmann: All jobs on the system are erased in 35 overwrite passes. An overwrite session consists of a lead-in of four random write patterns, followed by 27 specific patterns executed in a random order, and a lead-out of four more random patterns.
- US Department of Defense 5220.22-M: This is generally regarded as the highest level standard for sanitization to counter data remanence. It meets U.S. Department of Defense requirements for erasure of disk media.
- Custom: The system administrator defines the number of overwrite passes manually.
Implementing e-shredding in your large format workflow is an easy way to protect your confidential data. Don’t wait until it is too late and you security has been compromised. To learn more about secure data image overwrite technology on large format devices, read the whitepaper “Safeguard your Business’ Sensitive Data.”

In Part 3 of this series, I showed you some of the collaboration functionality of Autodesk 360. We are now going to look at how we can synchronize our documents and drawings using Autodesk 360, using a fixed location (PC on a network) and a mobile location (iPad on a remote site with Wi-Fi), like in Part 3.
Your Documents Are Ready To Go, What Happens Now?
In Part 3 of this series, I mentioned that your documents were already synced. The synchronization tools you get with Autodesk 360, either in your fixed location or your mobile location, give you great flexibility. Especially if you are mobile on a tablet such as an iPad. Any changes you make using AutoCAD WS (for example) can be synced up to Autodesk 360. Be aware, though, that you can store ANY kind of document on Autodesk 360. We are talking MS Word or Excel docs, not just drawings and models.
So like in Part 3, you’re logged in with your Autodesk ID and you have synced your existing documents from your fixed location (PC on the network) to the cloud (Autodesk 360).
Making And Syncing Changes In A Fixed Location
I have selected one of the Word docs I have uploaded, which are the three previous parts of this series. The selected document is “Intro to Autodesk 360.” You will notice I have control over comments (right-hand side) and I have commented “This document needs to be archived.” Currently, this document is NOT set to be shared. Public sharing is switched OFF (bottom). If sharing was on, the comments function is a great way to add “unofficial” comments on any document, drawing or otherwise, almost like you would talk to each other on social media, a bit like Windows Live Messenger, for example. It is a superb way of working in a fixed location and letting the staff on a site know what needs to be done, aiding productivity. There is also the facility to download the document, which I will discuss in a moment.
So, if I clicked on DOWNLOAD now, Internet Explorer (IE9 in this case) prompts me to Open or Save the document.
I am going to OPEN the document and as I have MS Office on my laptop at my fixed location, Windows will open the file for me and I can then get on working, regardless of where that document came from, which could have been a remote site on the other side of the world, again aiding productivity.
If I go back to my overall list of Autodesk 360 documents (just click on Documents at the top of the Autodesk 360 screen), and I hover over the document, you will see small icons highlighting that I have made a comment on the document.
When I click on the Actions icon (arrowed) and click on Versions on the sub-menu, Autodesk 360 give me a chronological order of the versions of the same document, allowing tracking of the document and its various versions.
The versions of the document are displayed on the browser screen as shown below:
I can upload a new version of the document, or if I click on the small clock icon, I can revert to a PREVIOUS version if required. Autodesk 360 prompts you about this if you decide to do it.
Making And Syncing Changes In A Mobile Location
So let’s look now at our mobile location. I am running Autodesk 360 and AutoCAD WS on my iPad, and I am going to change a drawing using AutoCAD WS.
Upon logging in to Autodesk 360 on my iPad, I see the recent history of the MS Word document. So, my changes have already been synced live in the cloud in Autodesk 360. This speeds up collaboration time, especially when working together as a team on project drawings where the masters are stored on Autodesk 360.
Using the same process as above to find a drawing this time, but using the iPad remotely on a Wi-Fi connection, I have downloaded the drawing A3 Training.dwg in to AutoCAD WS for the iPad.
If some changes are made to the drawing on AutoCAD WS REMOTELY, these changes will be synced to Autodesk 360 immediately when the drawing is saved. I have added two red circles to the drawing, as shown below.
After selecting Done in AutoCAD WS, the drawing is saved. I then need to select Sync in the drawing list and the new revisions to the drawing (the red circles) are then saved to that version of the drawing in Autodesk 360 as well.
Once the remote sync is complete (on AutoCAD WS), the fixed location can then check the changes on their Autodesk 360 back at the office.
By clicking on the Actions icon like we did before, and selecting Document Activity, you can see that the drawing was synced in Autodesk 360 only minutes before.
If you refer back to Part 2 of this series, I showed you how to use Autodesk 360 to work with updated drawings and how you can collaborate with your stored documents in Autodesk 360. With the addition of AutoCAD WS on a mobile device (in this case, the iPad), you now have the ability not only to collaborate, but design on the fly, using a mobile device and show the document changes in Autodesk 360 as you go. I stated that this leads to faster implementation of your design on site or on the factory shop floor.
Faster implementation and, as you now see, easy remote syncing of both drawings and regular documents makes for a much slicker workflow. The remote location using Wi-Fi and any kind of enabled tablet (not just an iPad, it could be an Android device, even a Kindle Fire) allows any organization to work GLOBALLY and almost anywhere.
The cloud is here and it is being used in many ways already. Autodesk are providing some superb tools that can be used with some of the cutting edge devices that are out there, such as the iPad, the Motorola Xoom (amongst many others). This technology WILL (and already is) revolutionizing the way we work with not only CAD, but with all the documents used in the design process such as specifications, OEM manuals and the like. A typical example was the MS Word document in this part of the series.
This is Part 4 of 4 for this series, so I bid you farewell for now but keep an eye for further blogs about tablet devices and mobile workflows!

In Part 2 of this series, I showed you some of the functionality of Autodesk 360. We are now going to look at how we collaborate using Autodesk 360, using a fixed location (PC on a network) and a mobile location (iPad on a remote site with Wi-Fi).
Your Documents Are Synced, What Happens Now?
Using AutoCAD 2013 In A Fixed Location
As mentioned in Part 2 of the series, all of the Autodesk 2013 product range now include an Autodesk 360 tab on the ribbon interface. We will be using this in a fixed location when you are already logged in. Click on the Online tab on the AutoCAD 2013 ribbon interface.
So, right now, you will have your Autodesk 360 browser window open (it works best in Microsoft IE9) and your AutoCAD 2013 is done and uploaded to Autodesk 360 ready to go. That is your fixed location all set.
Using Autodesk 360 In A Mobile Location
So now we need to think about the mobile location. I am running Autodesk 360 and AutoCAD WS on my iPad, so let’s check this out.
I first use my browser on my iPad (normally Safari by default) to logon to Autodesk 360. Once I am logged in, I can browse my documents in my Autodesk 360 folders. In this case, it is the AEC Plan Elev Sample Drawing, already loaded in Autodesk 360. I know this is a default sample drawing, but for speed’s sake, use this as the drawing you have just loaded up from AutoCAD 2013 to Autodesk 360, using the Online tab in AutoCAD.
I can click on the button shown and on the sub-menu, I can open up the drawing from Autodesk 360 using AutoCAD WS on my iPad.
Upon clicking on the Edit in AutoCAD WS option, I am prompted to install AutoCAD WS on my iPad from the App Store, if I haven’t done so already.
If AutoCAD WS is already there on the iPad, you just load up AutoCAD WS and the new drawing will be there in your drawing list, as shown below (drawing is at the bottom of the list).
You can now open the drawing in your mobile (remote) location on your iPad and edit the drawing accordingly based on whatever data you have at that location. You can now see the value of AutoCAD WS on a mobile device, as per my first series of articles about AutoCAD WS.
If you refer back to Part 2 of this series, I show you how to use Autodesk 360 to work with updated drawings and how you can collaborate with your stored documents in Autodesk 360. With the addition of AutoCAD WS on a mobile device (in this case, the iPad), you now have the ability not only to collaborate, but design on the fly, using a mobile device and show the document changes in Autodesk 360 as you go. This leads to faster implementation of your design on site or on the factory shop floor.
The cloud is here and it is now. Autodesk are moving forward fast with this technology and it WILL revolutionize the way we work with not only CAD, but all the documents used in the design process such as specifications, OEM manuals and the like.
As I said in Part 2 of this series, it will allow us to embrace the mobile CAD movement and start to mobilise the CAD office/function in ways we never thought possible.
Stay tuned for Part 4 of this series, where I will show you how changes in documents and drawings are synchronised using Autodesk 360.

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.
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:
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.

In Part 1 of this series, I introduced you to the new cloud-based collaboration tool from Autodesk, called Autodesk 360. In Part 2, I am going to show some of the functionality of Autodesk 360.
Once You’re Logged In, What’s Next?
Once you’re set up with your Autodesk ID and you’re logged in, what exactly can you do? What services are available? Well, if I went in to detail, I could write blogs about a mile long that would take you a week to read, so let’s go with something simple.
Autodesk 2013 Product Range
All of the Autodesk 2013 product range now include an Autodesk 360 tab on the ribbon interface. To keep it simple, I will work with AutoCAD 2013 on a PC workstation or laptop to show you how this all works.
Click on the Online tab on the AutoCAD 2013 ribbon interface.
You will see a group of ribbon panels that are grouped and incorporate relevant icons to work with Autodesk 360 from the AutoCAD 2013 application. The benefit here is that you can collaborate from AutoCAD straight to the cloud to other AutoCAD users and, more importantly, other Autodesk cloud users, who may be using other Autodesk products.
A typical example of this goes back to my previous blog series about AutoCAD WS, which features heavily in Autodesk 360 right now. As long as you are logged in to Autodesk 360 (click on the Autodesk 360 icon to do this), using the Share Document icon allows you to share the document (our drawing) in either Autodesk 360 or AutoCAD WS.
Autodesk 360 now updates in your browser, prompting you to Refresh List.
Once refreshed, Autodesk 360 updates your document list, and you can see the new document. In this case, it is an imperial drawing called Autodesk 360.dwg. Autodesk 360 shows you all 5 layout tabs available in the drawing.
So, if I now select one of the layout tabs in the refreshed document (drawing), I can start the collaboration process. As you can see from the screenshot below, I have plenty of tools to work with in Autodesk 360. I can toggle between layout views, I have a thumbnail view and I have zoom and text tools as well.
Now, the tools shown are purely for use in Autodesk 360 but if I select the Actions pulldown menu, I can then start collaborating via AutoCAD WS as well. Clicking on Edit Online in AutoCAD WS opens up another browser tab with AutoCAD WS and providing you are logged in, you can start to work on the drawing using AutoCAD WS.
AutoCAD WS can be used on a number of platforms, as per my previous blog series — PC, Mac, tablet and smartphone to name a few. This is where Autodesk 360 starts to really prove that the cloud will totally change how we work with Autodesk products.
As I have said before, Autodesk will revolutionize the way we work with Autodesk 360. It will allow us to embrace the mobile CAD movement and start to mobilize the CAD office/function in ways we never thought possible.
Stay tuned for Part 3 of this series, where I will start to show you have to synchronize your local/network locations to Autodesk 360.
