i made this tutorial, it's in a competition so if anyone here has an instructables account and finds the tutorial useful please vote for it. it is generally aimed at beginners with both programs so many of you will have advanced far beyond what it explains but for anyone new to 3d it could be helpful.

it also includes details on a sketchup to blender conversion method which seems to work every time, is absolutely free and preserves texture positioning(in my experience).
