OSnap Rhino8 not working

I’m continuing working on the file I was working on rhino 7. after upgrading to rhino 8 osnap is not working on the solids, curves, surfaces etc that were created in the previous version, osnap only works if I create them from scratch. help fix please.

That’s odd - can you post a file here to test? If not can you send it directly to tech support here: Rhino - Upload to Support ?

Perhaps also run SystemInfo in rhino 8 and post the results here.

it’s weird because i cut out a small part to copy and paste to another file to upload here and the osnap works if I take a smaller portion of the whole model and put it in a new file. if i copy and paste with all the model it still won’t work though.
