Looking for a recommendation for further design software.

There is BRL-CAD which is used by the US military so one assumes it has some depth to it. We haven't tried to use it ourselves so we can't comment on usability or functionality but it is free.

Don't waste your time with this. Tried it once. Didn't find it very productive. I doubt the military actually uses this.

Yes, we were not convinced it would be worth are while investing time in learning it we are just aware that it exists and is free. But you never know, our experience of freeware is that sometimes you can find some real gems if you are prepared to get past, what usually appears to be, a poor interface.

Absolutely. Unfortunately not in this case though. Firstly there is no UI, everything had to be typed in by hand. and the more complex your part got the longer each command got. For jollies I tried to design a little kids' rake for the beach. Took three days; with todays software this shouldn't take more than an hour. I also couldn't save to stp or iges (also done through a command line style editor.) No... not worth it.
