Good afternoon. I'm a watchmaker by trade but the current state of the world has left me in something of an employment corner. Watch work is a fantastic job if you can get it but there are only so many positions available. That said, I'm making myself step into the 3d CAD world. I have 0 knowledge, no good or bad habits. I'm downloading the personal/hobby version of the program as I write this. I'm going to start researching beginner and introduction videos on youtube and I may look into skillshare as well in good time.

My question is this: What are some genuinely basic things I should know, what are some of the traps or mistakes that new users make, and what can I expect or not expect out of the free version? I realize this is a very broad question so any and all information is highly appreciated. Any suggestions on particular users who have good education videos, websites or related content would also be deeply appreciated. Thank you!
