Cool and good luckl!
I've been playing with FreeCad, thought I'd do that before I spent $$$ on a printer. So far, I've drawn a box and a cylinder with a hole in it 
(and I was a draftsman back in the 70s).
Maybe if I had never been a pencil and paper type this would come to me easier, but so far this is kicking my butt. I've watched multiple videos (numerous times) to no avail. May be because I don't see myself wanting to sit in front of a computer all day trying to learn it at 69yrs old.
I haven't given up yet, hopefully the light bulb will come on before too long.
