■ Square grip. Reshapes the selected object by moving the base point or
changing the tangent direction at the base point. Use the three axes to
restrict the movement option to a specified axis. Similarly, the three squares
that touch the square grip restrict the movement option to the specified
planes.
■ Tangent arrow grip. Changes the magnitude of the tangent at the base point.
For example, lengthening the tangent arrow grip flattens the curvature of
the surface at the point of tangency. The tangent arrow points in the
direction of one of the surface’s U, V, or W axes, depending on the tangent
direction specified in
