STL and OBJ imports not showing up

Member Posts: 110 ✭✭✭
I'm testing out importing STL and OBJ files. They seem to import fine (don't report any errors, and say Translation completed), but most of the time I'm not getting an actual mesh file, rather only a tab for the imported file that says No preview available.
I've tried importing STL files as ASCII and binary STL. Does it matter?
Do the imported meshes have to be manifold, solid, have correctly oriented normals, zero intersecting triangles, etc, etc.?
What are the requirements that allow a STL or OBJ to actually show up as a mesh, vs just getting a tab that says No preview available?

Thanks for sharing the failed imports with support!
I tried an STL in your document, it didn't pass our validation. To check if the model uploaded successfully, you can click "show more" in the notification dropdown.
Some of the meshes have self-intersecting or zero-area faces. We're actively improving on repairing problematic meshes. More to come!5

i cant even see import anywhere created document no import went into document no import tried to drag and drop no import what am i doing wrong all otrher software has no problems impoorting this exact file
To import an STL file into Onshape:
1. On the Documents page, expand the Create pulldown and select Import.
2. Browse and select the STL file you want to import.
3. A notification will appear showing the import status.
4. Once imported, the STL file will appear as a new Document.
You can also import STL files into an existing document by clicking the Insert new element icon (plus symbol) in the bottom left and choosing Import, then browsing and selecting the file.
