Use this procedure to define the offsets of the net, usable, and gross boundaries of a space from the base boundary in the space style. Space boundary offsets can also be set manually. When the net, usable, and gross boundaries of a space are determined manually, they can be grip-edited. When they are determined from the space style, they cannot be grip-edited.

Space boundaries by style
- Click

- Expand Architectural Objects
Space Styles.
- Select the space style that you want to change.
- Click the Design Rules tab.
- Specify the distance to offset the net, usable, and gross boundaries from the base boundary:
If you want to… Then… offset the net boundary from the base boundary enter a value for Net Offset. Note: In many calculations, the net boundary is identical to the base boundary. If you enter 0 for the Net Offset, the net boundary is not offset from the base boundary.offset the usable boundary from the base boundary enter a value for Usable Offset. offset the gross boundary from the base boundary enter a value for Gross Offset. - Click OK.
