Offsetting Polygon Contours

 
 
 

Offsetting contours expands or shrinks the outline of selected polygons. Each contour edge is shifted by a specified amount, and remains parallel to its original direction in the same plane as its polygon.

   

Offsetting by a positive value expands the contour.

Offsetting by a negative value shrinks the contour.

NoteUnlike Inset Polygons (which is a special case of duplicating or extruding polygons), Offset Polygon Contours does not modify the topology. In this respect, it is like a deformation that applies only to polygons.

To offset polygon contours

  1. Select one or more polygons or polygon clusters.

  2. Choose Modify Poly. Mesh Offset Polygons Contour from the Model toolbar.

    If you did not select any polygons or clusters in step 1, you are prompted to pick them now.

    The picking session defaults to Rectangle Polygon selection, but you can change the selection tool using the commands on the Select Tools menu or the keyboard equivalent (for example, F10 for the Raycast tool).

    The outline of the selection is offset and the Offset Polygons Op property editor opens.

  3. Adjust the Offset as desired. Values are in Softimage units. Positive values expand the outline and negative values shrink the outline. A value of 0 has no effect.
