The Reshape tool can manipulate NURBS surface control points and reshape NURBS surfaces. For example, a dome or bell-curve effect can be created by manipulating the vertices.

This tool can potentially create surfaces which cannot be further manipulated.

To reshape a NURBS surface:

1.      Select the NURBS surface to reshape.

2.Click the tool and the appropriate mode.

Mode

Description

Move NURBS Surface Vertex

Changes the position of the selected vertex or vertices only

Move NURBS Surface U Vertices

Changes the position of all vertices in a row in the U direction

Move NURBS Surface V Vertices

Changes the position of all vertices in a row in the V direction

Working Plane Constrain

Moves the selected vertex or vertices on a working plane

X-axis Constrain

Moves the selected vertex or vertices along the X axis

Y-axis Constrain

Moves the selected vertex or vertices along the Y axis

Z-axis Constrain

Moves the selected vertex or vertices along the Z axis

To select one vertex or row of vertices, position the cursor over one of the NURBS surface vertices. When the cursor is over a vertex, the standard arrow cursor changes to an unfilled, four-way arrow.

To select several vertices at one time, click with the Shift key pressed or click and drag to create a marquee around the desired vertices.

If several vertices are selected, position the cursor over one of them.

3.Click-drag the mouse to move the vertex or vertices.

4.Release the mouse at the desired location.
