i know this is not possible right now, but I tested Alias and they have some nice tools to use a tablet to draw out plans by hand. Has anyone ever seen a plug in? It would be slick to be able to mock up concepts with a tablet and model them after, without having to import photoshop.
I noticed alias has some really advanced stuff for that that actually somehow works with the model. just can not wrap my head around it enough to understand what is involved.
