It's very tricky to use if you try to do complex projects. I try to keep things simple put a box in, then apply the texture, save it - and export it to Bryce to construct the building. I find the wireframes go crazy if you try to do too much - adding other primitives and glueing them - I spent alot of time trying to work it out, but decided that keep it simple is the best way. Now my problems are solved with the skewing of the imported model - I should be able to build with out the problems I was having. There is a website dedicated to Canoma at http://www.canoma.com/ Peter
