Parasolid vs SAT vs IGES

Parasolid vs SAT vs IGES

Parasolid vs SAT vs IGES

(OP)
It has come up at my company that we need to decide on a solid format for PLM.  Our parent company uses SAT files, but due to some known version issues I would like to use parasolid or IGES.  Any arguments for/against the above?

RE: Parasolid vs SAT vs IGES

For ... Parasolid is the native language of the engine which drives SolidWorks and therefor should be the most stable format for SW.

Against ... Not all programs can read/translate Parasolid. SAT might be the more universal format.

cheers

Excellent, thanks.. that is the kind of "ammo" i need.  What about IGES? similar issue, native to a specific package?

RE: Parasolid vs SAT vs IGES

In my post I should have said, "IGES might be the more universal format."

The SAT format is to the ACIS geometry engine as the Parasolid formats (x_t or x_b) are to the Parasolid engine. Both can be read by most of the programs which use either engines.

cheers

RE: Parasolid vs SAT vs IGES

My choices would be in this order: Parasolid, Parasolid, Parasolid, STEP, IGES, SAT

RE: Parasolid vs SAT vs IGES

I agree with dogarila's order. I suggest the same.
Except, I would move the 3rd to the beginning and swap 2 & 3. bigsmile

RE: Parasolid vs SAT vs IGES

Is there a preference for which parasolid to use? binary or not?

thanks,
Tom

RE: Parasolid vs SAT vs IGES

I agree that Parasolid is best for SolidWorks and for that matter UG products since they use the Parasolid kernel. However, if you are doing data xchange with AutoDesk 3D products, ACIS (SAT) might work better, since the kernel of many AutoDesk products is based on ACIS. You are correct that the version of SAT is actually critical for the data xchange to work (this is because AutoDesk does not technically use ACIS anymore, but a kernel that was based of an earlier version of ACIS).

If you are doing data xchange with products that do not use either the Parasolid or ACIS kernel, STEP might work best since it is a neutral format. IGES is another neutral format, but STEP is much more robust than IGES.

RE: Parasolid vs SAT vs IGES

If you need to communicate with those still using Autodesk products be sure to set Options to ACIS V7 on save.  Otherwise advise them to download the Hoops ACIS Viewer to convert down to V7.
