Hello,
The Tool Options that pop up with this icon look straight forward:
1-Either enter a Radius and that is what you control,
2-Or enter an Angle and that is what you control.
Well, it does not quite work that way. By default the radius is 1, if you change it and then specify a Base Entity it automatically goes back to 1. The only way is to first select the Base Entity, then change the radius to the desired value, that works.
If you first select an angle, as soon as you specify the Base Entity it reverts back to Radius 1. The only way I found to define the angle is first to specify the Base Entity, then select the angle wanted...but it will not accept more than 179°. With 180° it will only draw an arc determined by the last position of the mouse on the drawing, should you want to enter a higher value, it reverts back to 180°.

Help needed please.

Christian
