# Drag the mouse away from the origin to establish the desired X-radius. Left-click a second time.
# To establish the Y-radius and the hyperbola's leg length, drag the mouse to the desired location and left-click to complete the Hyperbola.
Â
NOTES, SPECIAL CASES OR EXCEPTIONS: Checking the box labeled '''Neg. Branch''' creates the opposite branch of the hyperbola curve. Checking the box labeled '''Create Half''' bisects the hyperbola and removes its bottom half. You can revolve the resulting curve to create a hyperboloid.

The diagram on the left provides a reference of the parameters controlled by the resize (RED) edit handles. Edit handles turn blue when the mouse cursor hovers on top of them. This color change indicates that the handle is active.
