To Create an Intent Surface Using Datum Reference Features
1. Click
Model >
Datum >
Reference. The
Datum Reference dialog box opens.
2. Under
Type, select
Intent Surface.
3. Select one or more edges, intent chains, or surfaces to define the datum reference feature.
|  You can also select geometry to define the datum reference feature first, and then click Model > Datum > Reference to open the Datum Reference dialog box. Intent Surface appears in the Type box. |
4. To name the intent surface, select the Intent Name check box. The Intent and Instance boxes become available.
| If you do not select the Intent Name check box, the intent object does not receive a descriptive name or a default name. On the Properties tab, you can change the name that appears in the Model Tree, but you cannot use this name to search for intent objects or to automatically place user-defined features (UDFs). |
5. In the Intent box, type an intent name, for example, DRAFT_SURFACE, or accept the default name.
6. In the Instance box, accept the instance number or type a descriptive name, for example, MOUNTING_BOSS, or accept the number.
7. To limit the references defining the intent object to one:
◦ Select the Single Item check box.
◦ Select a surface, an edge, or an intent chain to define the datum reference feature.
| When you select the Single Item check box, your previous reference selection or selections are cleared. |
8. Select the Dynamic Preview check box to preview the intent surface in the graphics window.
9. Click OK.
