I’m hoping I might get a poll from folks on this forum on the idea of Parasolid exports containing assembly structure. Siemens really only measures NX needs/wants based on IR generation, so the wants of NX users is probably not effectively captured if only IR’s are looked at.
Currently NX is the only major CAD tool that does not provide Parasolid exports with an assembly structure (flat file formats only).
Creo, Solidworks, CATIA, SpaceClaim, and even Siemen’s SolidEdge all provide Parasolid export with the option to include the assembly structure.
Who here would like to have NX also provide this Parasolid functionality (Parasolid with Assembly structure)?
Thanks!

Is your problem related to sending data to another system or simply bringing the data back into NX as an assembly instead of unparamaterized solids in one file?
If it's the latter, whether or not you get each solid as a separate component depends on how you read the Parasolid file into NX. If you use file->import->parasolid, then you will get a bunch of unparameterized solids in one part. However, if you open the parasolid file directly (file->open) then NX will create an assembly. See an example movie below:

While it is true that NX will create an assembly if you use file -> open, the structure may not match what you expect. If your assembly makes use of subassemblies, that information is lost and NX flattens your assembly to be one level deep.
Edit: the comment above applies to a "round-trip" of the data (exporting from NX then importing to NX). It is good to see that NX honors the structure exported from SW in the example below.

That would depend on what software created the outputted parasolid.
For example Creo, Solidworks, and SolidEdge all output parasolids with the structure included.
Here's an example using Solidworks:
Note the highlighted structure on the left...
Then the parasolid file imported into NX:
The resulting structure on the left is the same from Solidworks and contains the expected several levels of assembly structure:

I will forward this to the Product Manager. Hopefully he can do something about it.
