Dave, I do believe that's the one I'm looking for. You don't know how much time you've just saved me. Many many thanks Grant

A significant, and to me valuable, feature Pro has is the response of the Google QA team to bug input. The latest ones I have logged have all had very fast responses from them. They have been very good about chasing things down. Not quite as good as Lemkesoft but good none the less.

Hi Grant, There are lots of woodworkers around here who will be able to help you out with any design issues related to SU. As for rendering, there are a whole bunch of external rendering softwares - some more or less integrated into SU, some free, some cost a bit of money, some extremely expensive. Here is a link to a list of rendering applications. I myself have only tried out Podium (which is a not expensive, nicely integrated and easy to use renderer) and Kerkythea (which is also integrated, a bit more complex but free renderer) so far. There are people however with much more experience than me. Welcome to the forums, by the way...
