Can I control 'Feedback Mode'?

The display conduit doc page says:

  1. DrawOverlay : If Rhino is in a feedback mode, the draw overlay call lets temporary geometry be drawn on top of everything in the scene. This is similar to the dynamic draw routine that occurs with custom get point.

Can I turn on some sort of feedback mode (without using a Get()), so DrawOverlay updates without adding to the doc?



Just calling Views.Redraw() after updating conduit geometry seems to work and is fast enough. I didn’t realize Redraw() could be used to update conduits only.
