Best CAD format in Calypso (Large files)

[[Ri...]]

I have some large CAD files, upwards of 300mb.
Calypso (2021 and or 2019) are SLOW, slow in every aspect.
Offline or online, a single point can take upwards of ten seconds to create a feature, and its just a mouse click or physical probing on the model/part.
Is there a CAD format that will take some load off Calypso?
I'm not having any issues using CAD files in other CAD programs.

I'd recommend the format of GOM Volume Inspect 🤣

Hope this doesn't sound too goofy, but make sure you only have one file open.

I'd agree with only having one window open at a time.
Get a high end graphics card, make sure to set it to Autodesk motion builder - compatiable.

And if you are working with large complex assemblies with lot of nuts/bolts/washers and other unnecessary internals, etc - learn how to export a simplified CAD model in NX / Solidworks, or your favorite 3D CAD program. I've noticed huge improvements only working with the shell of an assembly vs. the whole assy model. The whole model will eventually become unuseable - memory leaks and acis crashes.

I already stripped about 50mb of misc tooling from the assembly.
I need what I have for avoidance while programming offline.

I don't think the CAD format is your problem: Every format you load ends up as a SAB/SAT model. That's what all the import options do. Just make sure not to import unneccesary layers. I don't mean washers etc, but design surfaces, invisible stuff and the like.

If all that has been optimized, it's mostly a matter of the graphics card and Calypso's efficiency. I can't rmember having much problems when just touching a point, but I've waited for hours for the simulation to chew through a seemingly simple part.
