Existing assemblies breaking

tony_459tony_459 Member Posts: 206 ✭✭✭
Again I'm seeing older assemblies that I've left in perfect perfect shape breaking with parts inexplicably missing and I cannot possibly make the time to go back and redo these assemblies yet again.

Onshape, what gives? Requirement number 1 of a good CAD platform would seem to be that a valid CAD model today is a valid CAD model tomorrow if you haven't modified it in the meantime. No?

But I never know which of my models will break next. I have a beautiful helicopter assembly that was practically finished and which is now half vanished---literally. The whole powertrain for the rotor is just gone, no trace of it left behind whatsoever. Poof. That took *forever* to model. Now all gone.

And a rocket model that I put months and months and months into is itself now swiss cheese, with many critical parts totally missing. I loved that model. Now it's just swiss cheese.

Can we agree that it's important that our CAD models be stable and not randomly break when you haven't modified them?

    Please file a bug and share your documents with support. We are doing a lot of testing to prevent this sort of breakage, but some issues hide from us. Apologies for that.
