Re: [CAD_CAM_EDM_DRO] Re: CAD experiment entry

I forgot to talk about draft angle. I have used this for some time as I
make foundry pattern that must include draft.

I first started using planes to make angles when I was studying for my
CSWA exam. (Certified Solidworks Associate). That is the lowest level of
certification offered by Solidworks. I am now boning up for the next
level, where parametrics is king. Most of that test has equation driven
models that must be changed quickly to have enough time to finish the test.

1. This is what I have done...
2. This is what I think...
Be aware of the difference!
