The information in this article applies to:

 Softimage 3D for IRIX, versions 3.51, 3.7 == Softimage 3D for Windows NT, versions 3.51, 3.7 == 

= SYMPTOMS =

A scene containing Trim NURBS elements with modeling relations is loaded over another scene that contains Trim NURBS with modeling relations. The Trim NURBS elements in each respective scene are part of the same hierarchy and when the hierarchy is translated, the modeling relations are lost.

= CAUSE =

The Trim NURBS elements with modeling relations were part of the same hierarchy; this is considered an illegal operation in SOFTIMAGE 3D. When there is a modeling relation involved, you cannot include the Trim curve, the original Trim surface, or the Trim result in the same hierarchy or branch.

= RESOLUTION =

Leave both the Trim curve and the original Trim surface at the default 0,0,0 world coordinates (the modeling relation is Global and not Local). Now you can select the Trim result only, and when you transform the Trim result, the modeling relations are not lost. You can then load a second scene containing Trim NURBS with modeling relations. As long as you respect the conditions listed above, you will not lose the modeling relations in your scene. The Trim results can also become children of other branches or hierarchies without causing problems.
