Sketch Fillets and Chamfers - Toolkit

Hi everyone.

I searched in the toolkit manual, forums and examples, and i didn't see nothing that allows me to do fillets and chamfers in sketch environment.

In this moment i can get the entities, such as lines  and points, but after that i can't find any functionalities that allows me to do the fillet or chamfer.

Anyone knows how to do a thing like that?

Best Regards.
