Newbie to CAD could use a hand

SheetCAM is pretty much the de facto standard for work going to a CNC plasma cutter.
 
Found an old copy of sketchup on my old computer i was going through a few months ago. I did a course with it whenever i was in highschool. I started playing with it and kinda got back into the groove a bit. fast forward to me buying a jackhammer for our excavator and now needing a quick attach to hook onto it. company wanted $2k++ for a ready to go one. so i whipped up the bit in sketchup, emailed a dxf file to my buddy at the steel fab shop and have the bits for about $700. an evening of welding later and voila!

Probably not the best program for making drawing but in this case it worked out.
@dialedin More pictures! How big is this? How thick are those hooks? Any shots of the Jack hammer mounted?
