i can quickly edit 2d and 3d faces and vectors with autocad. you just have to know what your doing witch just takes practice. at work i draw all parts that we make with CNC 3d in Autocad and then import them to mastercam to program the machine.

in my experience with any program buttons are great for beginning because you don't know the software that great but when you get better they just slow you down because you have to switch your brain from tracking the geometry of your part to tracking your mouse pointer to click a button and then back again. With autocad you have buttons and you can customize them so you can do everything with buttons or you can use the command line you can also repeat your last command by just hitting enter.

Anyways... I mean to say autocad is wikid fast. although some geometry like spirals helix's i forgot the word for this one but its the shape you make with a spirograph. and some more advanced calculus related curves and such. the programing for them just isn't there in autocad. But on the bright side you can download these little LSP. files with have math in them and you can do those things.

in the end. I'm still waiting for a cad program that i can do everything in and has a command line.
