To Create a Datum Plane and Adjust Its Display by Reference
You can size datum planes to visually fit a part, feature, surface, edge, axis, radius, point, or vertex.
1. Click Model > Plane. The Datum Plane dialog box opens.
2. Click the References collector, and in the graphics window, select placement references for the new datum plane.
* 
To add multiple references, hold down the CTRL key while you select.
3. Select the required constraint option from the constraint list in the References collector.
4. Repeat Steps 2 and 3 until you have selected enough constraints. You might have to select additional references to make the datum fully constrained.
5. Click the Display tab.
6. Select the Use display reference check box, and then perform one of the following actions:
To use an item within the model as a size reference for the datum plane display, click the reference collector, and then select a part, feature, surface, edge, axis, radius, point, or vertex as a size reference.
To set the default for new datum planes to use an item within the model as the size reference, set the datum_display_default configuration option to referencesize.
To use the entire model as a size reference for the datum plane display, do not select a size reference.
To set the default for new datum planes to use the entire model as the size reference, set the datum_display_default configuration option to modeloutline.
7. Click OK.
