User Guide

A curve point and its BCPs lie on the same segment. Each
BCP (and its curved segment) is affected by the movement
of the other BCP. Dragging one of a curve point’s BCPs in
any direction will result in the other BCP moving to maintain
the straight line.
Dragging a corner point’s BCPs
A corner point’s BCPs generally lie on top of that same
corner point.
To select an incoming or outgoing BCP:
1. Hold down the Option or Alt key before clicking on
the control point.
Moving or adjusting one of the corner point’s BCPs does
not move the other BCP or its attached segment.
2. Hold down the Option or Alt key, click on the point,
and drag out from the control point.
Dragging a tangent point’s BCPs
A tangent point’s BCPs always constrains to the tangent
(that is why they are named tangent points). Consequently,
a tangent point’s BCPs can never be moved away from the
tangent line. Moving the BCP will not change the slope of
the curve. The Option or Alt key can be used to select the
BCPs that lie on top of a tangent point.
