Google has released a free version of SketchUp, an excellent 3D modeling package they acquired in the @Last Software acquisition awhile back. While not really a drawing and inking tool, the program does work well in some early testing on a Tablet PC using the pen to manipulate the various functions and create objects.
"The new Google SketchUp is for the do-it-yourselfer, the hobbyist — really anyone who wants to build 3D models for use in Google Earth. Go ahead and model that new kitchen, or deck, landscape your virtual garden, or impress your teacher with a roller coaster or medieval castle. When you’re finished, place your model in Google Earth. There! The beginning of a virtual world. Warning: don’t start messing with this stuff after dinner because your first experience could be an all-nighter… making an idea come to life in 3D can be very addicting"
There is also a Pro version for sale.
