How do I restore original constraints when opening a STEP file in Inventor?

How do I restore original constraints when opening a STEP file in Inventor?

How do I restore original constraints when opening a STEP file in Inventor?

(OP)
The original file is a Pro-E assembly model of an aircraft seat frame. They have shrink wrapped it and emailed it to me as a STEP file. When I open the STEP file in Inventor the constraints are lost. Is there a way to restore the constraints. I accidentally posted this question in another forum and was re-routed here. Any advice would be appreciated.

RE: How do I restore original constraints when opening a STEP file in Inventor?

Yes, recreate them just like the original modeler did in Pro/E or just like you would normally do in Inventor.
There is no other way to have constraints go from one program to another program.

That's Insane and very frustrating to read. There has to be an add-on somewhere for this. Grounding the parts works, but does not allow me to create animated presentations. I have read something about a Feature Migrator somewhere. Have you heard of it or used it?

Feature Recognition restores feature tree/sketches in parts. (to some extent)
Available on the Autodesk App store.

Assembly constraints are not part features.

How is this "insane" that no CAD programs will translate proprietary constraint information?
Perhaps you should notify the government and ask them to step in and do something about this.

Hmmm. Well thanks for the sarcastic response. It is not proprietary if they are our partners and we are working as team to design the seat for the customer. Thank you anyway. And by "insane," I meant the loss of time it would take to sift through the models and re-constrain screw holes, hinges, lids, panels, sheet metal, switches etc. without any clue as to the original dimensions they were first given.

The proprietary information that is the topic of your original question is the assembly constraint solver and file formatting the CAD company builds into their software product.
They want you to use their product and reject all others.
