I recently bought Pro-E "WildFire", the version sold the first quarter of 2005. The PTC salesperson promised a feature known as ISDX, interactive surface design or something like that. I am told that its features are accessible via the "style" pick on the "insert" menu. So far, no dice. It's not working. Neither the VAR nor PTC sales have returned an email or a phone call about getting ISDX working on my machine. The other features appear to work all right. I'm finishing the second run throught the cell-phone tutorial. I'm curious why it is so difficult for PTC and the VAR to deliver on something so simple. What are other people's experience with getting this feature to work ? Thanks.
