Good for you sir!
The term "draughtsman" is all but lost now.
Have you noticed that as draughtspeople got introduced to computers they all suddenly became "engineers"? A term protected by law in many European countries and rightly so.
I've worked with draughtsmen and I've worked with chartered engineers. There's a bit of a difference!
I have also fiddled with some computerised engineering packages, mainly CATIA and Alias. I found CATIA to be longwinded beyond words, but Alias was remarkable, if only because I taught myself from one of its 12 manuals (!!) and within an hour, had a rendered perspective of my own Albatross speedboat rotating in front of me. I do wish the same author would write all manuals!
What's freeship? It seems interesting that several of the more popular 3D programmes started out as design aids for ships and aircraft, such as CATIA, Rhino3D, etc. NURBS modelling was invented to create those irregular but fair curves we all strive for.
But it still gives me a nice feeling to see a "proper" drawing!
