After over 30 years in the CAD business there are a few things I've learned:
1: Keeping things SIMPLE is always the best bet.
2. Just because you CAN does not mean you SHOULD.
3. Nobody ever knows it all
4. Whenever the hype seems too good to be true, it's not true.
5. Nothing worthwhile is easy no matter how much "they" tell you it is.
6. There is always more than one way to model the same thing,
7. Cheating in modeling techniques will ALWAYS come back to bite you in the behind.
8. No CAD software is truly "better" than another. It's the Driver behind the mouse that makes it great or a POS.
9. Every "enhancement" hyped by the "Man" is simply the spit shined version of the blood, sweat and tears methods us "Geezers" figured out long ago.
10. Be true, honorable, truthful, teachable and willing to pay forward the skills you have attained.
