In Inventor when you wanted to sketch inside a part, you could create a plane and then press F7 and the model would split and hide half the part along the sketch plane. This made it easier to see what and where you were sketching.
When you had finished sketching you pressed F7 again and the hiden half would come back.
Is this function or something similar in SolidWorks, or is it not needed.
