If this model is a mesh (.stl) then this is ok. Shapr3D can’t edit meshes this way.

In this archive same model in two different formats you can compare.

Thanks for the help guys, found the problem. It was right after a boolean subtract the black lines dissappeared so not sure why, but at least i know where the problem was. Im sure that should not happen though, how would you make edits when you cant select a face or an edge. It just becae one clickable body after boolean.

If everything is as you describe and you can reproduce it, then it’s worth writing a bug report to Support.

Because this is not expected behavior — nothing like that should happen after a Subtract operation.
