I'm not convinced that it's Creo_Pro-E that is to blame for your difficulty with this. Different CAD systems have different capabilities, methodologies as well as strengths and weaknesses. I think the real issue is that your methods were developed using whatever CAD system you've been using and probably learned on. The approach taken with one CAD system isn't necessarily appropriate for another one. Sure, your basic extrudes and revolves are the same...... You could reverse the entire situation and give someone who knows Creo and tell him to do the same thing with another CAD system and he'll have difficulties as well.
This is very similar reasoning as a lot of new people use, they want to try to force the CAD system to do what they think it should do rather than realizing that you have to learn how to learn and leverage what it does do. More often than not, the people who have been creating these programs know a whole lot more about it than a newby does, no matter how smart the believe they are. The biggest problem I've seen is people who think remembering the training course material is all there is to learning to utilize a CAD system, it really is just a starting point and nothing more.
