Creating Contours

Contours are intersections of a solid or surface with a plane passing through the line specified with the Create Contours tool. This tool creates contours at specified intervals, which can then be used to create a loft surface in order to re-create a solid shape.

 

To create contours:

1.	Click the Create Contours tool from the 3D Modeling tool set, and then select Preferences on the Tool bar to specify the contour interval.

To create a single contour, specify a Contour Increment of zero.

2.	Click and drag to indicate the position of the intersecting plane.

The contours, a group of NURBS curves, are drawn in red.
