All tools that require the sketcher should zoom in on the centerpoint being used to complete the feature.
An example would be when making a sweep surface. After choosing the trajectory, and entering the sketcher to build the sweep section, the center of the sketcher is in some unknown place. Sometimes the model is not even visible. This requires panning and zooming to find the centerlines and centerpoint. If the centerpoint was automatically centered on the screen it would save a great deal of time. Oddly, sometimes when editing the sketch the centerpoint is automatically centered onscreen.
