I used Assembly Boolean to create a single part of all of the parts in my assembly. This was nearly 4 years ago and I may have done something wrong. Now I would like to use that assembly again (all as separate parts) but it has disappeared. Is it possible to "unassemble" the .sat back into the separate parts? I though possibly the file just got misplaced or saved unintentionally somewhere else but have searched everywhere. The odd thing is that the 2D drawing of the assembly still opens and all parts are visible.
