2. Click Add. The Custom Property dialog appears.
3. Enter a descriptive name for the user-defined field in the Name field, then click OK to return to the Custom Properties dialog. You must enter a unique name for each user-defined field: the name must not be shared with any other properties that are displayed on the IFC Properties pane.
