Imported Solidworks Datasmith missing faces and objects

Hi guys, I am trying to import a solidworks assembly into Unreal, but I found two strange things:

1, lots of actors without any mesh attached to them. Is there any way to quickly delete them to simplify the scene without manually delete them?

(Some actors without mesh serve as the parent of a group of objects. I should totally keep them intact.)

2, lots of meshes with missing faces. I checked, they are not caused by flipped normals. Those faces are indeed not imported.

3, I also noticed that all the small screws and bolts are not imported by default, which makes me really happy. I guess there’s a threshold somewhere in the importing process that will automatically skip objects too small? But I do want those missing faces to be correctly imported.

4, some parts with thin thickness also got skipped during import. You can see the panels here are all gone.

Any tips are much appreciated.

Hello,

  • which version of the engine are you using?
  • are you importing .sldprt/.sldasm file inside Unreal or are you exporting .udatasmith from solidworks and then importing that in UE?
  • In any case there should not be missing geometries. By default there is no function that would remove anything from the CAD model.
  • Lately we have some instabilities with the default tessellator, si you can try to use the one from Techsoft while we improve the UE one (CADKernel). For that you can deactivate CADKernel using this CVar ds.CADTranslator.DisableCADKernelTessellation true

Would you be allowed to share the model with us?
