Turn On Tracing for MapTool

MKa

I would like my drawing tool to default to Snapping to Vertices and to Enable Tracing mode on Activate.  I have easily figure out how to enable Snapping, but i am not able to enable Tracing mode.  In arcobjects I was able to do this with the TraceConstructor/ShapeConstructor.  How can i do this in the new version so that the tool defaults to the trace mode.  Here is what I want to do so far.  I create a polylie that snaps, but i also want it to trace using the standard trace option.

Yes, executing the constructor command is the best way to do this.
