直接建模真的没有参数吗？？ (2009-02-01 09:41)

Great write-up Coop! Business is changing right now (and I'm not talking about the current economic conditions- which is all you seem to hear about on the news). It's changing in ways that will see "companies" look more like a collection of suppliers and temporarily hired guns working on bits of products "virtually" from all corners of the world. This idea that you can open and edit models in any CAD format will be required to support that new reality.

As for today, there are a ton of areas where Direct Modeling offers value to folks who could be using 3D- but who can't, won't, or shouldn't climb the learning curve of a traditional CAD tool. These are untapped areas of productivity hiding in the existing workforce.

Course, I work for SpaceClaim and am a bit biased. I do want to point out one wrong assumption a lot of people are making as they learn about Direct Modeling:

Many people think Direct Modeling means there are no parameters, because they are seeing it being positioned in opposition to traditional "Parametric" CAD tools. This is just an error in symantics causing some confusion. You absolutely can setup parametric relationships within Direct Modeling tools like SpaceClaim. You just get the freedom to set them up on-the-fly. And, you only need to define the parameters that you really care about, where traditional CAD requires you to manhandle every feature and parameter. And yes, it is possible to control these parameters from outside the DM tool... at least, I know that's true for SpaceClaim.
