You can also right click in the Graphics window, select References, and select one or more surfaces as references.
 | You can also first select the surfaces and then click > or > to create a mold or die volume. |

| | You can specify negative values if one of the selected surfaces exists inside the volume. |
8. On the Options tab, in Overall Dimensions, specify overall dimensions for each direction, if required. The overall dimension is symmetrically applied in the respective direction. Any change in the overall dimensions alters the linear offset values that are set in the previous step.
9. Click the Envelope check box to modify the dimensions of the mold volume so that no offset is applied to the volume.
| | If you click this check box, the specified linear offset values are reset and are not available. Clear the Envelope check box so that the linear offset values are available. |
