Curve driven pattern

I am a university professor in process of converting my freshmen CAD class from SolidWorks to Onshape. One assignment teaches students about curve-driven patterns. I have them model a cogged v-belt. The cog is an extruded subtraction and SolidWorks has no problem patterning it around the perimeter. The attached graphic shows that Onshape is struggling and only creates patterns along the straight sections but not around the curves. Any ideas?
Thanks,
Aaron

You might also need to make sure the "tooth" cut sketch extends in the empty space past the edge like this to avoid causing "zero thickness" geometry as it goes around the corners.
The best way to do this is actually to pattern a body instead of a feature, it will regen faster (in this case about 3x faster in a quick test case I did). i.e make the tooth a new part, and curve pattern that with the "remove" option. The tooth extending past the inner edge of the belt is also required here.
