The manual has some cool tutorials which are easy to follow but they take time. The easiest I think is to use the spline modeler. Say hand, spline modeler, front view, click on pen, make points for shape of hand, then click curve tool and drag the handles to make the finger tips and so on. The geometry sym in plane, add point at halve way point then curve tool again and you should have something that resembles a hand. I made the pot for the tree using the spline, making the outline for the outer part of the pot and then used the torus and then stretched it out to make it oval. Hope this makes sense what I am trying to say. Try it. Dave
