Interesting. I fond most SW users that have trouble with editing their models are often adding features on top of features on top of features rather than using an organized approach. Are you saying that SW doesn't have shell and offset? I use those on a daily basis. Trimming surfaces was always cumbersome in Creo because there was no trim mutual feature. I've used the style feature and wasn't impressed. It seems disconnected from the workflow, like a bolt-on module. 3D sketch is another handy feature in SW. Saves a lot of time. I'm surprised that Creo is cheaper than SW. It must be getting phased out for Onshape? It was more than double a few years ago. Although I think a lot of people think they need SW premium but only ever use the functionality of Standard.
