Fiorini- I always "work" with perspective turned off, I think it looks like it might be turned on bc there are angles to some of the parts. For whatever reason my mouse still jumps back while finishing a relationship.
Mark- I am editing the definition to finish the three relationships using flash fit. I find this easier than going to home tab, assemble group and individually selecting a relationship.
*on a positive note, I contacted GTAC and they helped me with my driver/texture issue. Long story short I had to re-install solid edge.
One thing that has helped me with this is to get the view I want on screen before I start adding relations. I believe (just by the way the software behaves) that the pick window for an object is calculate based on what is displaying at the time the command starts. Thinking this way have saved me some frustration.
