Summary: Ability to have a true center line.

Description: In sketch mode, provide a "Centerline" option in addition to "line" and "spline".

How Used: Currently, a centerline is really just a line with a different linetype applied. When creating a centerline, without using the "Fix" constraint, it's difficult to make centerlines appear like a crosshair (like one draws centerlines in 2D design). If you use an implied constraint to the centerpoint when creating a line, it is NOT fixed in that location (hence requiring "Fix" constraint).

Using ProENGINEER as an example, it has a centerline tool. It snaps to a point you select and then allows you to place it horizontally, vertically, or at an angle. It also extends infinitely, to some degree, without zooming out infinitely.
