Our company is frustrated as well with the lack of being able to get a resolution to some very basic issues with Creo.
There are some real weakness with sketching in Creo.
I've submitted 1 idea submission in specific that we would like resolved. Nothing at all gets done. I talked to Brian Martin about this specific issue and he brought this issue directly in front of the PTC developers. They said it already was fixed, and he explained how it was not fixed. Even though they said they would look at the issue nothing was done. Fresh this year I submitted essentially the same issue as an idea because I couldn't locate my original submission.
Every once in a while in a forum thread you see a developer come into the discussion and they suggest it gets submitted as an idea to get the issue acted on. Evidently this process is just a mirage.
