Fix Importing Large Files

AuroraRon

I am experiencing constant import issues with Onshape when working with large files. Despite using Onshape for seven years, I have yet to notice any improvement in this area. I love using Onshape, but working with files that are not created in Onshape becomes very difficult or impossible. I would settle for just a shell, but parts with errors keep wrecking the complete assembly.

What format are you importing and which CAD system did it come from?

Inventor is one of them.  Supplier just tried again to export as a Parasolid and it just fails to translate.  I just created another support ticket.

We also have no luck with step for engines, always errors that cause it to be unusable.  I have many examples from different engine companies you can try.

After seven years....

Your support ticket:
 "Failed to import parasolid"
has been identified as a bug and we are working on it. As soon as this gets addressed and is pushed to cad.onshape.com, we will update this ticket to so you can confirm the update.

Lets hope importing large assemblies finally gets some attention.  It really bothers me to see all the advertising trying to get solidworks customers to switch over and when you do, it takes seven years to address the issues with imports not translating correctly or failing all together.

I tried to import another file today and waited two hours for Onshape to process only to end up with another unusable assembly. 

Does anyone know of a way to convert or import a Parasolid or stp file to one big solid or shell so that I can at least show something on a drawing?   It's been like this for every large assembly since I started here seven years ago and still nothing from Onshape.

Have you tried importing in another CAD program? I keep a (free) hobby license of Fusion360, and if something does not come in clearly in OS, I try it in Fusion. I think "from memory of the last 3 years", anything that failed in OS also failed in Fusion.

Thank you, Nick.
The demos I've tried so far have file size limitations.

After seven years of using Onshape, I still can't get any large file format to import into Onshape that is remotely usable. It does not matter who the source is. Will the importing from other formats ever be fixed?
