Example: Creating an Arc using a Target
When you create a 3 Point/Tangent End Arc on an existing endpoint, Sketcher displays a target symbol attached to the endpoint. To create a 3 point arc, drag the cursor out of a quadrant perpendicular to the end of the entity. To create a tangent end arc, drag the cursor out of a quadrant tangent to the end of the entity.
