I am working with hand drawn pattern instructions and converting them to CAD, so this may seem a bit odd. I've attached a drawing to illustrate.
If it was paper, the original pattern would be slashed at the Center Front line nearly to the other edge, then the pattern is spread out. The edge line retains its length and the individual sections retain their width.
I've tried different combinations of tools in QCAD, but I end up distorting something in the process. I'm sure this isn't a one-step process, so whatever it takes to accomplish this is fine. Any suggestions?
