Copy/paste in edit mode in Blender 2.8 Normally, I would agree that copy/paste is not necessary with the duplicate functionality (shift+d), but in this case, I think I have a legitimate reason to ask it.

I am working on a game that detects continuous pieces of same-material mesh to perform specific things with them. So now I have a mesh body where I need to bevel some edges (for aesthetic reasons) into new faces and change the material. I need these new faces to be disconnected from the original mesh while the original mesh stays connected because of what I said above (the game engine needs it).

The way I want to do it is given below:


bevel the edges
copy these beveled faces to the clipboard
undo the bevels
paste the beveled faces from the clipboard as new mesh


Is it possible at all?
I suggest that instead of trying to copy and paste the bevel as a new object, you should simply duplicate the mesh you have, leaving one copy the same, and using the other mesh to create the bevels you wanted.  Simply create the bevels, and with the bevels still selected, hit ctrl-i to invert the selection, and press delete.  This way you end up with just the beveled mesh, yet you still have the original mesh to keep.

Hope that helps.
