How long and much effort does it take to design and produce a piece? Is it hard to learn how to use the software to a decent standard?
Well, once I get really into a piece, it goes rather quickly. My main problem is having to go back and redo parts as the assemblies come together, so as to maintain a sense of scale and continuity. It also helps to have a good ruler with fine tick marks (a micrometer would be even better), and an existing part to start from. The sonic lance arm was designed to be roughly the same size as the pulsar arm, at it helped to have one to measure for reference.
As for the ease of use of the software, I'm not the best person to ask - I've had to pick up how to use the software at work. It's not really a requirement of my job, but knowing how to use it helps to convey information to the drafters/designers that would be hard to fit into words. I dabbled in making 3D models about 10 years ago, but for the last 3 years I've gotten alot better since I've had my current job. It's really just about breaking down a complex part into a bunch of simple parts.
BTW, I made all my stuff in Autocad, of all things. It is definitely not the best at 3D work, but it's available to me and I have lots of people's brains I can pick at work when I get stumped. It doesn't handle free-form shapes very well (at least I have figured out any easy way of pulling them off), but most things can to faked as extrusions or lofts along a path. At least so far.
