# Drag away from the focal point and left-click a second time to set the desired Offset.
# Drag and left-click a third time to complete the Parabolic Curve.

NOTES, SPECIAL CASES OR EXCEPTIONS: The parameters '''Axial Length''' and '''Aperture''' adjust the size of the opening of the parabola. Changing the value of either one automatically adjusts the value of the other. Checking the box labeled '''Create Half''' bisects the parabola and removes its bottom half. You can revolve the resulting half-curve to create a paraboloid.
