Arc from center, radius, begin, and end points

This selection constructs an arc with a specific center and radius with the starting and ending points determined by angles.

1. Select Construct tab > Geometry panel > Arc > Center Radius Start End to enter arc-creation mode.
2. Enter the radius in the R field.
3. Pick or enter the location of the center point.

5. Enter the End Angle in degrees.

   If the Relative option is deselected, the angle is absolute measured counter-clockwise from horizontal. If the Relative option is selected, the angle is measured relative to the Begin Angle.

6. Click Create to create the arc.
