3D Graphics Performance Improvement In ZW3D 2012

About a year and a half ago I did a series of 3D graphics performance tests on my Dell Precision M6400 and compared various CAD systems. Today as I was playing around with ZW3D 2012 (previously known as VX before VX Corp was acquired by Chinese CAD software developer ZWCAD), I came across a claim from the company that they had significantly improved the 3D graphics performance of ZW3D. So I decided to figure out exactly by how much, if at all.

Here is how I navigated around my test engine model in VX 14.3

At that time I commented:

“As you can see, VX has some serious issues with regard to large models. Parts of the model go missing completely. No shaded representation, no bounding box, no nothing.”

And this is how the same engine model behaved in ZW3D 2012 on the same hardware.

Significant improvement indeed.

Another thing. ZW3D 2012 now sports what they call a “native” STEP importer and exporter. Previous versions used software from TransMagic, which were actually repackaged libraries from Spatial’s 3D InterOp. After looking at the DLL’s in the ZW3D 2012 installation folder I get the impression that ZWCAD went ahead and licensed the libraries directly from Spatial. The fact that ZW3D 2012 can now export a ACIS SAT without the need for a TransMagic license is another indicator.

Also ZW3D 2012 has been ribbonized.

But the rest of the UI has remained pretty much the same.

    You should have used a V10 engine they are way quicker ;)

    Perhaps graphics have improved but they have done things like going into beta for 2012 with lathe for cam but no posts. Lathe was a big deal new feature but as far as I can see it will not happen until a year or so after the pretty icons appear on the tool bar. The only post written at this time is for an obscure Turkish controller that as far as I can tell by links on the manufacturers web site is used solely on domestic Chinese cnc lathes.  Imports with parasolids are still a problem with files from SE. I am pretty certain that since Siemens owns the parasolid kernal the problem is not at their end. Direct editing is still very crude.  Still 32 bit and I watch in task manager to see tool paths max out at 2.7 gig ram while my cpu loafs along at 16 or 17% and watching, waiting and hoping the tool path will finish this time is not productive. Yes it does look prettier but I am afraid that to is where their emphasis has been instead of improving many other areas.

    Good to see the real change of ZW3D 2012 as their promise, now my big files works pretty good with the graphic enhancement. Ribbon interface is nice, but that is the most important for me, I found that there are more stuff in sketch and 2D sheet, it is said that they would have the more professional Mold module, but I still couldn’t get the chance to try it in Beta, hopefully they still keep their promise.

    sorry for missing my point in the previous post, that is why I post it again.

    I am happy to konw ZW3d will integrated the turning model, I thought that first version might be not perfect, but it is a good start. As I kew, they would offer Post for Fanuc, sinumeric and fadal in this version. what’s more, post can be customized on the post configuration interface, that we can create posts base on different controllers by ourselves.
    By the way, I am also looking forward to the enhancements about CAM. Such as the undercut in 3x operation, operation folder creation and auto assign feed and spedd, etc.

    ZW3D is a lost cause.
    After all this time the software is still DECADES behind the competition.

    I tried the evaluation version of ZW3D. One thing that struck me as different was that the user can select a solid face and just delete it using the delete key on the keyboard. In all other packages the entire solid gets deleted. In assemblies this has absolutely no effect on mates and the tree doesn’t show errors if a face or facet of a part has been accidentally deleted.
