FilletCorners is a great time-saver for rounding corners of polylines. Now I wanted to use ChamferCorners, but it’s not there. 
For now, just call ChangeDegree to 1 on the result of FilletCorners.
This does not work that well on polycurves where some segments are not linear. I’d like ChamferCorners added as well… thanks.

@chuck Just tried it. First I used FilletCorners with radius 1, then I did ChangeDegree to 1, and that gave me a chamfer with distances 1, 1.
Thanks for the suggestion!
