I tried using "Find Intersection" on a drawing to dimension to a virtual sharp on a radius. In one case, two extension lines extended from the part edges to show the intersection. In another case, no extension lines appeared. Instead, a very long line appeared to the side of the drawing paper. What am I missing here? Does it make a difference if the part shown in the drawing has a fillet from a fillet feature rather than from a fillet created in a sketch?
