Are you an Industrial or educational user?
I am a UK educational trainer and we normally give support to those we train.
I was also trained, industrially with Solidworks as well as being about to complete training as an Inventor eduactional trainer. I am still finding features in one piece of software that I like, so I go back to one of the others, particularly Creo and I find how to do the same in that software.
One thing I do wonder about with CAD trainer is that many move too quickly onto complex methods rather than fully investigating the basics. In schools I feel the earlier they are introduced to the software the better their grasp of it. Very early usage could be likened to play - no worries just see what you can do, problems just put it in the bin and have another go.
In the 70's Art School lecturers had a day when they had to work on their own stuff, perhaps CAD users would benefit from some play time in their week or possibly month.
Try to find time to have a play yourselves, and share the results
Perhaps we need a site where we can share ideas and finds and not, as I have been doing bitch about particular software - rather like a good news program with no bad news allowed!
