Add Valley Trusses

You can use this function to define a valley truss area, and add trusses to it with even intervals. In order to define the shape of the valley trusses, select the upper and lower structures limiting them, for example the slopes of the crossing roof and the main roof.

1. Select Trusses > Special Trusses > Valley Trusses.
2. Select the truss parameters. The previously selected parameters are the default parameters. You can reselect the parameters by using the function Edit truss parameters on the contextual toolbar.

3. Select the upper limiting structures. Select several slopes with the Ctrl key pressed down or by using area selection.
   
4. If necessary, edit the truss area by adding or removing sections of roof slopes. You can select following auxiliary functions from the contextual toolbar:
   • Add Slope Extension
   • Set Slope Shape
   • Cut Slope Shape
   • Define Limiting Plane
   • Deleting Slope Shape
   • Editing Slope Shapes
5. Select Confirm.
6. Select the lower limiting structures, for example the slope of the main roof.
   
7. Select Confirm.
8. From the contextual toolbar, select the location method, which will determine the point from which the positioning of the trusses will be started.
   • From Left to Right
   • From Right to Left
   • From Both Ends to the Center
   • From a Selected Point in Both Directions
   • Center Point of the Interval in the Point Selected
9. If necessary, select the truss adjustment for gable trusses. When you select the adjustment, the truss edge will be positioned in the selected truss line point.
   • Adjusting First Truss
   • Adjusting Last Truss
10. Click the truss line points, or the first and last truss position. The centers of the trusses are positioned in the selected points, unless you have selected the truss adjustment for the gable trusses. Please note, that the trusses are created perpendicularly to the line between the selected points.
    

    The program adds the trusses.

    

Note

• If a truss would be positioned on a chimney, it is not added.
• You can later edit the truss area using the following functions:
  • Edit a Truss Area - editing involves the exact same steps as adding a truss area.
  • Update Truss Shapes - you can reselect trusses' upper and lower structures. In addition, you can define the distance between the top or bottom chord of the truss and the limiting structure.
  • Generate Trusses - you can reselect truss parameters.
