Not a bad idea Mark. I don't think any one person has ultimate knowledge of the elusive and cryptic Profile Modeler. If nothing else, we could just start a general profile modeler thread where everyone plays with it and posts their results/observations. We would be able to flesh out some bugs that need to be addressed at least. We've spent many many hours over the past week or two trying to get it to behave predictably for this simple mitering job, and only managed to get the job done by trying to fool the PM into behaving.
