In my case its said with a tongue in cheek.
I've begun working with DoubleCAD and I'll freely admit I'm struggling up that first hurtle of learning a new program. Last time I had my hands in a cad program was in 1987, things have changed. I've surfed through youtube for some beginner's guides and googled importation of blender files (where the source of my graphic is coming from). The latter I haven't had much success with, so I'm guessing that I'll need to build the part in cad from scratch.
Anyway, as I've said before, learning new things is a worthy endeavor. At least the minute examination of my source has lead me to notice that its layout is not dimensionally true - meaning the lines don't line up. one step forward ...
