You can use the Part-Editor for many reasons. In this Tutorial, we add sketch-loops for Profile/Extrusions. However, the Part-Editor is not as powerful as you might find in your solid modeling software. If you add many sketch-elements and sketch-constraints, the Part-Editor may slow down as you edit or add even more constraints. Out request is that you do not add complex sketches to a Part.

For speed:

•Break down a complex sketch into smaller, simpler, separate sketch-loops.

•To specify the position of each sketch-loop, add dimensions from the X-axis or Y-axis for at least one Point in the sketch-loop, and then dimension sketch-elements relative to each other.
