Re: CAD experiment idea

My suggestion would be that everyone start with the dimensions already written down so there is
taken in figuring out what exactly you are modeling.

As far as machining goes, this is a CAD model of a finished part we are shooting for. How to machine
it has no bearing.

Planning your steps in the CAD is part of drawing the model so that all counts for time.

Regarding threads, cosmetic threads not needed. Just put them in the CAD model the way you would if
you are going to use the model for your CAM program.

Regarding fillets and chamfers, as I posted separately I would suggest only fillets or chamfers on
the vertical edges of the flange and a chamfer on the top of the threaded hole.

Hmmm...
How long it takes to draw depends on how much you want to go into details such as filleting and
especially the exact shape of the threads. It also depends on how much of the pre-cad work you count
in the time--just as you have to plan machining steps, you also have to plan drawing steps in the
CAD program.
