SE PMI is pretty darn good. It just needs a couple of enhancements to bring it home.
1. We need to be able to associate mulitple features to a feature contol frame like a pattern of holes and postion. And surfaces for profile.
2. The JT font could use improvement. But what we really need is the appropriate highlighting of features.
3. It would be nice if the principal views in SE agreed with the principal views in TCV.
