Inventor to Creo workflow

[gilsdorf_e]

Hi,

I have found various posts about importing models from Creo to Inventor, but nothing about the other way around.

Does anyone have a good best practise for that? We are talking about Inventor 2022 to Creo 7.0. That means Creo cannot import Inventor files directly because 2022 is not supported yet.

Requirements would be that the file name can be transported, maybe also material naming. Important to the customer is also weight and center of gravity.

I tested a bit, so far STEP looks most promising. However some details are not working. For example weldment assemblies.

Weld beads have a material assigned in Inventor and are also exported and imported as solid bodies. However they have no density in the exported STEP file. I'm not sure if that's intended.

Honestly better off asking on a Creo' board.   Maybe a few others over there that might have the answer.

For:

For example weldment assemblies.

Weld beads have a material assigned in Inventor and are also exported and imported as solid bodies.

Likely till 2022 is able to be import, they won't know how to do a Weldment / importing of the bead.  It's an after affect in the IAM of the weldment and not actually part of any part. So it doesn't know how to handle it likely.  Where / what file would get the bead?

Don't get me wrong, I do not expect the weld bead to become a weld bead in Creo. I only want it to affect the overall mass. For assemblies with a lot of weld beads, that could make a difference. Inventor exports it as part/solid in STEP but with no assigned density. That seems inconsequent.Even more, Creo will not calculate a global mass, if parts with density "0.0" are inside the assembly.

I believe the mass is due to it coming from an import and doesn't know how it should calculate it.    Assigning it a material properly.

What about adding something to the idea's station .. an option to convert all welds to say an IPT and have it assign a material?

Oh, actually density and volume are included in the STEP file, so Creo will calculate it from there (as long as all geometry can be solidified, which is sometimes a mess).  But I'm now looking for a way to include mass and COG in the STEP file. There is a property in the STEP file for overall mass of an assembly, but Inventor seems to set this always to 0.001, even if the mass is calculated in the Inventor assembly. 
I might move this topic to the idea board, thank you!
