Hello! I hope this isn't too terribly annoying. I have recently discovered the Sketch Designer, and I love it, but I have one serious problem-- Why does the Sketch Designer draw the inside bits of a model, like the teeth and the eyeballs? Is there any way to stop it doing this? I have tried to discover this on my own, but on a soooo slooooow machine it's a bear and a half, so I turn to you good people: how, please? Also If anyone can point me to tutorials on the Sketch Designer, I'd appreciate that very much. Thanks!
