Tutorial: Creating UDFs Using On-Surface Coordinate Systems

Creating UDFs Using On-Surface Coordinate Systems


Creating UDFs Using On-Surface Coordinate Systems Theory

The placement of a User-Defined Feature (UDF) gains some capabilities when the features used to create the UDF reference an on-surface coordinate system. Upon placement, the UDF will appear in a dynamic preview that can be dragged to locate the UDF. You can also specify an additional rotation angle for the UDF.

Keep in mind the following regarding the on-surface Csys and UDFs:

- The features comprising the UDF should reference ONLY the on-surface Csys. They should not have any parents other than the on-surface Csys in the model from which the UDF is created. To simplify this, create three orthogonal datum planes through the on-surface Csys to act as a set of "default datum planes."

- If an on-surface Csys is included in the UDF features, the UDF setup will require prompt creation only for the references of the Csys.

  • When placing the UDF in this case, you can select references to place the on-surface Csys in the destination model.

- If an on-surface Csys is NOT included in the UDF features, the UDF setup will require the creation of one prompt for the selection of a coordinate system.

  • When placing the UDF in this case, you have the option to create an on-surface Csys on-the-fly.
