Rounding Dimension Values from 3D InterOp

Wed Aug 16, 2017

 Recently I was asked a question about one of the standard test files generated by NIST (National Institute for Standards and Technology) that was being translated by our 3D InterOp translator.  The question concerned the diameter of a hole in the geometry with a dimension on it specifying ⌀0.238, which sounded innocuous enough at first.

One-Way Associativity for 3D CAD Analysis Applications

Tue Mar 1, 2016

Analysis applications often use solid models generated by CAD systems as their input; for example, the structural analysis of an engineering model. The user of the system applies a set of loads and boundary conditions to the model, and then the software performs its analysis and supplies a set of deformations or stresses in the material, allowing an engineer to look at the results and decide whether the design fits its purpose.

Top 5 Things You Should Know When Considering Data Translation

Tue Apr 2, 2013

1. Don't Reinvent the Wheel
You're designing a new product, but you have an old part that's almost right for the job. Don't redesign it from scratch, import it from its source format and tweak it to meet your current needs.

2. Keep it Tight
If you're designing a part for manufacturing, you need the end product to be water-tight. If your model is “leaky”, your production run might just sink before it gets ever gets launched. If you’re re-using data files and they are not in the best of shape, importing them may help to patch some of those holes during the healing phase and make for clear sailing during production. In this way, data re-use not only extends the life of the model, but it may very well make your model ship-shape to boot!

Getting the Point about Points

Thu May 24, 2012

Two weeks ago, Spatial hosted a booth at the CONTROL Exhibition in Stuttgart, Germany.  I hate to follow John's recent post with another one about a trade show, but this one is worth discussing - let's just call it "Interesting Shows - part 2."

Desperately Seeking System Tests

Thu Dec 9, 2010

In one of my former lives as QA manager, one of the problems that continually grated on my nerves was the mysterious nature of our nightly regression test failures. Our test suite was incredibly fragile, such that in analyzing failures during our convergence period to determine whether they were truly indicative of a potential customer problem or just whiny tests, I was constantly faced with making decisions based on vague error information emitted from black box tests of unknown origin. A lot of manual analysis was required for every release.
