Removing part of a sketch

Discussion created by Guest on Jul 14, 2005
Sketched a sheet metal part, then wanted to remove a section of it. Could find no way to cut/delete/remove/erase/reposition. Also could not back up in the design tree to go back to before that section was added. Very frustrating, yet this is such an obvious thing that a user would have to do.
I stopped being impressed by the software at this point -- strikes me as incredibly poor user interface. Hate to have to redo the entire sketch and waste all my time, but it's the only answer I can find. Also can't cut and paste entities into a new sketch. I seem somehow to have locked the part and can't make any changes to it. So what obvious, simple thing am I missing?
