Transform Axis to Axis

The Transform feature is a type of feature modifier. This capability modifies a set of functional features of the active body by applying a transformation to them individually. The affected features retain their full functional behavior.

 

  • The command allows you to define four types of transformations:
    • Translation - Translates one or more features.
    • Rotation - Rotates one or more features about an axis.
    • Scaling - Resizes one or more features based on a ratio factor.
    • Symmetry - Applies a Symmetry transformation by reflection.
    • Affinity - Transforms the absolute size by multiplying a scale ratio.
    • Axis to Axis - Transposes the geometry from one reference axis system to another.

    An “Axis to Axis” transformation transposes all the geometries of the selected features from one reference axis system to another. The transformation that is applied to the geometry is the delta transformation from the reference axis to the target axis.

    • Reference and Target Axes are required:

  • Reference: The axis system to map the geometry from.
  • Target: The axis system to map the geometry into.

This scenario illustrates an Axis to Axis transform applied to a functional feature (Pocket).
