roundCorner

Creates a new shape, rounding a single corner. This assumes paths is defined, and contains a single list (i.e. is a simple polygon, with no holes).

NOTE, some operations (such as union, difference and intersection) do not guarantee a predictable ordering of the shape's points, and therefore the behaviour may depend on the version of Foocad. Therefore, it is safer to use roundCornerNear instead.

The number of sides used to construct the rounded corner uses a similar default to that used by Circle. But you may override the default by using roundCorner (Int,Double,Int).
