@SEPM. Gérald : Your list is impressive, you must have spent a lot of time compiling all this! Courage that I didn't get ^^ In any case, a big thank you! I'll complete my list with yours as well.
@flegendre: Your tutorial is very good => rated and commented!
And as I do Frenchy, American, aluminum for chassis I was tired of spending 2 days associating pieces of tube with a family of parts. So imagine when you make small chassis, big chassis, aluminum chassis.... etc
Now a chassis is a 3D sketch and 15 min (coffee included) to have the right size and the right positions.
And you get your speeds out in the same way.
On the other hand, big problems with solidworks if you make several chassis in an assembly you don't know how to bring out the total flow (cf a colleague who makes balconies)
