The biggest problem IMO with Creo is the UI sucks. So because it’s so bad, if you don’t have someone to tell you many of the little secrets, (like hotkeys and mouse shortcuts that don’t otherwise exist in any logical format) then you might also develop bad habits.
Unlike Rhino or Alias which are much more free-flowing and “dumb”, working in parametrics even for a surface model still requires a good foundational understanding of the feature tree, references, etc to make your workflow better and reduce the misery downstream. In Alias if I don’t like something in the history tree I can blow it away and start fresh or ignore it. In Pro E that one feature may be critical to 300 other features, meaning model structure and best practices are still important.
