Toolbox Icon:

Draws a circle which is tangent to three lines. The three lines must lie in the same plane unless you are currently in 2D Mode.

Point 1: First line tangent to circle

Point 2: Second line tangent to circle

Point 3: Third line tangent to circle

There are three choices for how you want to save the circle:

Circle: Stored as an actual circle in the drawing plane circles can be shaded.

Line: Stored as a line entity. This makes it possible to scale the circle or treat it as a line entity with other commands.

Set a point on each of the three lines. A circle is drawn tangent to the three lines.

NOTE: If the three lines do not lie in the same plane, and the circle is drawn tangent to the three lines while in 2D Mode, the circle is drawn at the Z coordinate the cursor was on before the switch to 2D Mode. This will be apparent when you switch back to 3D Mode.

N Segments: When saved as a plane or line, this is the number of segments, into which the object will be divided.
