Displaying Massive CAD Models Using a Gaming Engine

Last year was when CAD vendors first realized a market exists for mobile apps. Two weeks ago, we talked about the two approaches: mobileCAD tethered to desktop software and not tethered. Last week, a significant shift occurred: for the first time, several CAD developers announced Android versions first, saying iOS was to come.

 

This week, we take a look at a somewhat different approach. A developer in Switzerland takes data from Inventor and displays it on Android devices and Web browsers using a gaming engine. CAD systems like having multiple gigabytes to work in; phones and tablets are . The problem is, how do we stuff huge files with lots of ancillary support files (fonts, xrefs, images).

 

I emailed last week with Paul Schuebach of CAD Software Solutions. "Basically, we create and run 3D spare parts catalogs for customers. We believe that this business model can be very interesting for small and middle size companies -- no large upfront costs for software, along with the savings of not creating paper catalogs."

Q&A

upFront.eZine: It appears to me that you are using the graphics engine from Unity3D to display 3D models from Inventor in Windows, Web browsers, Android, and soon iOS?

 

 

Mr Schuepbach: To review 3D content we use the Unity Render Engine for web browsers in Windows, Mac, and Android; and as a standalone application for Win, Mac, and iOS. (We have completed the iOS version, but it's just not yet in the AppStore.) Mobile devices and the standalone versions can also save content (the models) locally for offline work without a connection to the Internet.

 

upFront.eZine: How do the 3D models from Inventor get "converted" to the format needed by Unity3D?

 

Mr Schuepbach: To convert CAD data to Unity data takes several steps. It depends on the size of the models (or the number of parts). This can be as few as three steps or as many as eight steps for large assemblies. Please understand that I cannot go into the details; this is our know-how to be able to load a machine model of more than 100,000 parts via the Internet in very short time.

 

 

upFront.eZine: I notice that your Web site has demos of models running in Unity3D. I assume that you create custom solutions for clients?

 

Mr Schuepbach: We build custom solutions for clients, but our main focus is to offer the following services:

About Unity

As it turns out, it was games that made Windows acceptable for CAD. Microsoft needed 3D games to run fast on Windows to convince people to switch away from MS-DOS. The optimizations that helped games (OpenGL, DirectX, specialized graphics drivers and input devices) also helped CAD run faster. You could say that 3D gaming development subsidized 3D CAD development on Windows.

 

CAD Software Solutions adopted Unity 3D, and Unity says it can stream anything to the Web player or application, such as textures, animated models, complete or partial scenes, and user-generated characters. Unity takes care of the following functions:

A license to basic Unity is free, which runs on Windows. Add-ons for Android and iOS start at $400 each. See http://unity3d.com/unity/licenses for more details.

ZW3D 2012 Press Briefing

ZWSOFT technical manager Colin reminded me right off the bat that ZW3D is already 25 years old, being based on VX which his company acquired nearly two years ago. For those unfamiliar with VX -- er, ZW3D -- it is known for being a CAM system with integrated CAD. It has its own Overdrive modeling kernel and performs hybrid solid and surface modeling. You can design parts in its CAD module, or else bring in models and tweak them before generating the CNC code in the CAM module.

 

Normally, ZW3D costs in the range of $2,500 (3D CAD and sheetmetal only), $4,000 (adds mould design and reverse engineering), to $7,000 (adds 2-, 3- and 5-axis CAM).

What's new for 2012 is a dramatically lower price for the new two-axis machining package: $1,500 for solids-based CAD and 2X milling and turning + import translators from Transmagic for Catia, NX, SolidWorks, Inventor, Creo, and ACIS. (A similar three-axis package adds 3X miling and costs $4,000.)

 

So that's the price plunge. Here's what else is new in ZWCAD 2012.

User Interface & Translation

New to ZW3D is the ribbon interface, which displays mini help in large tooltips. Surprisingly, it took until 2012 for the software to get hotkeys, aka customizable shortcut keystrokes -- along with Windows-standard keystrokes, like Esc for cancel and Del for erasing selected entities. Mini toolbars appear when you right-click the mouse. Mouse buttons are also standardized, such as holding down the middle button for real-time pan.

 

The display performance is 2x-3x faster, coming on top of the up-to-10x increase with the last service package. Also added: real-time drop shadows and anti-aliasing for smoother curves. TrueType fonts are finally supported.

 

As I noted earlier, ZW3D now includes import translators from Transmagic, and so can import files from Catia and NX down to SolidWorks and Inventor -- at no extra cost. It also exports in 2D and 3D PDF, as well as 3x faster STEP import and export.

 

Direct Editing

ZW3D does history-based and direct editing, and in this release direct editing was improved. The dynamic coordinate system now attaches itself to the face or edge being edited. Edges and curves can be directly extruded into surfaces; smart regions select appropriate faces. And lots more.

 

One new feature I found particularly interesting is the selective Boolean operation. Colin showed how he could subtract a shape from several stacked solids -- and specify that just a few of them be cut through.

 

There are many additional changes to sheet metal design, the new mould design module, smart ribs (where Booleans take care of ribs that intersect extrusions), 2D drawing sheets, and so on -- plus 2X, 3X, and 5X machining.

 

Q&A

I asked Colin how direct editing changes the history tree. He said that the results are added to the tree.

 

Can ZW3D covert between surfaces and solids? Yes, it can switch back and forth. He showed me how he could convert a complex 3D solid into surfaces, add fillets, and then convert back to solids.

 

ZW3D 2012 is currently in beta 2, which you can try out from http://www.zwsoft.com/en/zw3d-2012-beta-test.

Autodesk is offering 0% financing when you purchase a license to Autodesk software through one of its resellers, until mid-April -- or until $8 million in funding is dished out -- and you spend at least $10,000. They note also that Autodesk 2009 software loses upgrade pricing and tech support after March 15. [What did customers do to deserve such short-term support?] http://imaginit.com

     In unrelated news, the 2013 line of Autodesk software will no longer support the Vista dialect of Windows, officially. [I am sure the software will run on Vista, since Autodesk will still support its software running on XP. It's just when you call for support, all you'll hear is a dial tone -- or something.]

 

Tekla BIMsight v1.4 has a user interface optimized for tablet computers, such as multi-touch and stylus use. [Hmm... I didn't know there still were any tablets running Windows.] http://www.tekla.com

Letters to the Editor

 

Re: Two Approaches to Mobile CAD

"We will push an update to the Glovius Android app this week, with a big performance boost, cross-sectioning & file associations. A note on tethering: Glovius for mobile + Babel3D.com can serve as a fully independent solution, without any dependency on the desktop applications. Babel3D.com provides a cloud based interface to translate files to the mobile optimized format and the mobile apps provide an intuitive consumption mechanism. (just like Gmail).

 

"We believe the mobile 3D space will see adoption with non-consumers first. And initially, its features will pale in comparison to the desktop counter-parts. With this approach in mind, we do not see any reason to make the two solutions (desktop & cloud + mobile) inter-dependent, as currently they serve two completely different set of users. We share your opinion that untethered is better for the user!"
      - Siddhartha Oza, Product Manager

Re: Introduction to Solid Edge and Synchronous Technology

"Wrong: '"However, when we compete with them head-to-head, we can win on functionality, ease of use, and quality.' Solid Edge is missing CAM functionality. Solid Edge can't win when a customer wants integrated CAM. SolidWorks has at least 10 CAM packages that run inside it. Solid Edge still has none. The next Solid Edge release (ST 5) will have a cool new icon. When you depress this cool new icon it will automatically call a local Siemens NX salesman. This is the only way a Solid Edge user will ever see integrated CAM."

Re: PTC Faces 2012 with Cuts, Reorganization

"Restructuring does impact the VARs. They use have a line set at $750M: VARs sold below this line, and [PTC's own] direct sales above. The line has been lowered to $250M."
