3. Click the start point of the arc.
4. Click the second point on the arc.
5. Click the third point on the arc.
   • The third point can be the end point of the arc and can be located between two points.
   
   If you select the first point from the end point of a line, the program draws an arc tangential to this line by default.

   • In this case, you only click the end point of the arc.

     

   • You can enable or disable the tangential feature by using a button on the mini toolbar. The button is displayed, when you slightly move the cursor up and to the right from the start point.

     

   • When the feature is off, you click the arc with three radius points.
