BUG: Modelling Relations Can Cause Movement in an Object
Last reviewed: April 19, 1996

Article ID: Q149730

The information in this article applies to:


 * Softimage 3D for IRIX, version 3.0

SYMPTOMS
Extrusion modelling relations can cause exaggerated movement to occur in the generated object.

After you create an extrusion modelling relationship, plot the shape to the generated object, and then cancel, the generated object displays exaggerated movement whenever the generator is moved, however slightly.

CAUSE
This bug may have to do with having reset cancelable operations whereby canceling the outer operation (freeze) does not also cancel the inner one (plot shapes).

RESOLUTION
This behavior does not occur if, in the Freeze Modelling Relation dialog box, you click Okay instead of Cancel.

STATUS
Softimage has confirmed this to be a bug in the Softimage product listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

Steps to Reproduce Problem
To reproduce this bug, complete the following steps:

 In the Preferences->Create Modelling Relation menu, select Get->Primitive->Circle. Select Surface->Extrusion. Click Okay. Select Effect->Freeze->Modelling Relation. Click the Plot Shape button that opens the Plot Shape dialog box. Click Okay. Click Cancel. Change the D window to Schematic mode.</li> Select circle1.</li> Press the v key to highlight the TransXYZ buttons.</li>  In the C window, drag the circle a little to the right. Note that the extruded object moves way off and up to the right. </li></ol>
