The Associated Elevation Planes dialog specifies where grid lines appear in the model. You can place grid lines only where grid planes intersect elevation planes. Therefore, you must place at least one elevation plane and one grid plane before you can successfully use this dialog.
Grid lines displayed on
Specifies how you want to choose the elevation planes that the grid planes intersect. The selected elevation planes will display a grid line.
If you select All Planes, all elevation planes that the grid plane intersects will display a grid line. In addition, if you add another elevation plane that intersects the grid plane, that elevation plane will automatically display a grid line without having to select that elevation plane in this dialog.
If you select Selected Elevation Planes, only the elevation planes that you specify in the Selected Elevation Planes list will display a grid line.
Available Elevation Planes
Displays all elevation planes that intersect the active grid plane. Elevation planes in this list will not have a grid line.
Selected Elevation Planes
Displays all elevation planes that you have selected to have a grid line.
Add
Moves the selected plane from the Available Elevation Planes list to the Selected Elevation Planes list.
Remove
Deletes the selected plane from the Selected Elevation Planes list. When a plane is removed, it appears in the Available Elevation Planes list.
