Prior to Inventor 2013 I could down load a STEP or SAT file from a suppliers website that has a stupid amount of detail in it. Once I opened the file in inventor I could right cick on the base feature and enter Solid Editing and delete the feature I do not want slowing down my model.
With 2013 Solid Editing opens Inventor Fusion or trys to open Invnetor Fusion to allow me to remove the features i do not want in my model. I have been weighting for 10minutes for Fusion to open to remove some threads on a dowel pin I down loaded. Unfortunatly I could have modeled this pin in about 1 minute...
The old method of solid editing actually worked! Invnetor Fusion is slower then Inventor R4 and is just about as useful.
If it isn't broke, DON'T FIX IT!
Wish list item: Dump Inventor Fusion, Bring back Solid Editing.
PS still weighting for Fusion to open.
