Insert Valley Set Grid

• Select a truss system grid (which doesn’t belong to the main roof)

• Select Insert Valley Set Grid directly from Truss+ menu

• A valley set grid will be automatically created

Note: Roof with a lower ridge is not the main roof

• It’s not possible to insert the valley set grid to the main roof, as the main roof doesn’t need the valley set grid

• If the selected grid belongs to the main roof, an error message will occur

• To change a parameter of the main roof:

• Click OK to close the error message

• Select the truss system grid and go to Modify Truss System Grid

• Uncheck the option Valley trusses will not be used and click OK
