Dear Community:

I try to make a chamfering toolpath with Profile Contouring strategy, 

1. is only profile contouring strategy support chamfering machining? i had tried Curve Following and Point to Point, but the toolpath are not so good.
2. in chamfering machining, we usually extend the toolpath in axis and radial direction so that the tool tip will not touch the part, which make a better tool life. in profile contouring strategy, i can set the precise parameters to adjust the toolpath, is there any more convince way to get this.

3. and for close feature like this ,how can we change the start point in any place we want? i tried First/Second Relimiting Element parameter, it not works.

Thanks in advanced.
