A few words about getting started...
Have
fun with the software and try not to get bummed out when the sketch or
model doesn't turn out exactly like you thought it would. Often, you
can learn as much from a mistake as you can from "getting it right".
When
your constructions don't turn out exactly as planned, pause to observe
the sketch. Ask yourself, "What is going on in this sketch? Do I notice
anything interesting? Is any part of the sketch the way I wanted it to
look?" Learn as much as you can from it, then back up and try again.
