Scaling using Fixed Size scaling constraints

The following example shows you how to scale the body of a wine glass, while keeping the stem of the glass the same length.

1. Define the stem surfaces as a user-defined feature.
2. Using the Set Constraints for feature dialog, add a Fixed Size constraint on the user-defined feature in X, Y and Z direction, moving the Z coordinate of the origin of the Constraint Plane to -33.72899.

   

3. Scale the wine glass uniformly by a factor of 1.2

   

   The body of the wine glass is scaled, but the stem of the glass is the same size as the original.
