3 The steps of an arc definition with its start, end point and tangent:
4
5 1. Define the start point of the arc by giving coordinates or [[image:1584703466987-640.png]] mouse-clicking.
6 1. Define the end point of the arc by giving coordinates or [[image:1584703467770-405.png]] mouse-clicking.
7 1. Set the tangent side with [[image:1584703474122-637.png]] mouse-clicking. Define the tangent direction from the start point with a third point (e.g. a point on a tangentially connected line) by giving coordinates or [[image:1584703469324-692.png]] mouse-clicking.
