That's cool.  You can import several types of drawing formats into OnShape as well. 

I have not looked at any YouTube videos but that is at least partly because I have used their free self paced courses quite a bit.  If you have not used them, they can be pretty helpful and there are a bunch of them from basic to advanced topics.  My problem is that I can do certain things in Sketchup so quickly, especially related to woodworking, that I do not often try those things in OnShape first.
