To Specify UDF Placement Options
1. Create a UDF.
2. Click Model > User-Defined Feature. The Open dialog box opens.
3. Select a UDF group file and click Open. The Insert User-Defined Feature dialog box opens.
4. Click OK. The User Defined Feature Placement dialog box opens to the Placement tab.
5. Define placement references and click Options.
6. Specify the placement scale by selecting one of the following options:
Keep dimension values (default)—Keep the same numeric value for all dimension values, regardless of any difference in units for the model and the group. For example, the dimension 25 inches becomes 25 millimeters.
Keep feature sizes—Keep the size of the features and convert the dimension values according to the target model units (for example, millimeters to inches). This option is available only for models and groups that do not share the same measurement units.
Scale by value—Scale all dimensions by a specified scale factor. Group units are not changed. Enter a value in the Scaling factor text box.
7. Specify how non-variable dimensions are treated by selecting one of the following options:
Unlock—Visible and can be modified
Lock—Read only
Hide—Not visible
8. Add or remove features from the Redefine these features list to specify which features will be redefined during UDF placement. Features with variable elements are checked for redefinition by default.

10. To remove all the redefinition done during UDF placement, click Undo All.
