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.
  4. Enter the Begin Angle in degrees. This angle is measured counter-clockwise from horizontal.
  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.
  7. When you have finished creating arcs, exit arc mode.
