The best file formats for exchanging data?

The best file formats for exchanging data?

The best file formats for exchanging data?

(OP)
Howdy all,

I have a general question about the differences between file formats and what is best.  As a creator of solid models, I know that the best file format is the one that the people I'm sending my models to to be turned into a physical part want. But in saving my SW files to various file formats I was wondering...

What's the difference between STEP 203 and 214?

What's the difference between .DXF and .DWG?

How does IGES stack up against these?

What else do I need to know that I don't?  (concerning this topic of course)

at the moment I'm working mostly with sheetmetal to be cut to accurate shape with some minor brake forming on a couple of parts, or honeycomb aluminum core to be cut to shape and beveled.

Thanks,

-Kirby

RE: The best file formats for exchanging data?

From SW10 Help: The STEP translator supports import and export of body, face and curve colors of STEP AP214 files. The STEP AP203 standard does not have any color implementation.

Having posted all that, I have never had an issue sending Parasolid files unless the end user can't use them.

RE: The best file formats for exchanging data?

We use iges only as a last resort, prefering just about any other neutral format, or even native which we will translate ourselves over iges.

RE: The best file formats for exchanging data?

Agreed parasolid then step AP214.  IGES is the absolute last resort.  Most of the time when we import IGES there are errors that import diagnostics can't fix.  Step can usually be fixed by import diagnostics if errors occur.  Parasolids don't usually have erros.

Isn't parasolid perfered for SW because of the kernel used to write SW?  What about Pro E, SE, UG etc. do they use different kernels?

Sorry don't mean to hijack your thread...

Grunt,

You're welcome to open the discussion in any direction you see fit.  I find it instructive.  I don't know that much about the parasolid file format.  I think I need to study up on it.

Parasolid is the modeling kernel for both Solid Edge and NX (AKA, UG).  It's also licensed to several other vendors of CAD software products who utilizes Parasolid in various ways as outlined on the following website:
