>>5794220if you want to do shit like that you NEED CATIA
I only know two surface design (that's what you need) programs and Simens NX sucks dick
with catia doing that vaza would be pretty easy and it would be probably impossible in Inventor
you can also read a book about catia's functions
it tells you how the program creates even the most complicated surfaces using only liens, points and planes
it helped me a lot
also do you know how to designate the beginning of the radius? that's the most useful shit ever
