Truss Builder
Creates and builds trusses
and roofs. Place only one truss at a time, or place trusses for a complete
roof, including gutters, attic floor, and gables.
Use the Truss Builder dialog to choose a truss configuration and enter the appropriate values for Span, Wall Height, Eaves Height, and Pitch. Values can also be set for a number of options including Floor, Facing Brick, Gable, Inside Wall, Truss Nose and Thickness.

Current Settings | Displays the name of the settings file that is currently loaded. |
Type | Sets the truss type to be built and placed: |
Span | The horizontal distance between outside edges of the outermost supports. Also known as the nominal span. |
Wall Height | The height at which the truss is placed relative to the data point or active ACS plane. |
Height AGL | The ridge (peak) height above ground level. The height measured from the bottom of the wall to the top of the truss ridge (peak). |
Left/Right | The variables pertaining to the left/right top chord of truss. Left/right values can be automatically synchronized by toggling the lock icon. |
Pitch | T he slope of left/right top chords in degrees. |
Eaves Overhang | The length by which the truss extends past the outside edge of the outermost support. |
Lowered | The amount by which the bottom chord is lowered.
Keep in mind, the elevation of the bottom chord will still be relative to the
wall height.
Note: If the
Lowered value is too small, a red circle displays below the Lowered text
fields. Red circles indicate an invalid structural engineering truss design. By
entering a higher value in the Lowered text fields, the overhang results in a
valid solution and green circles display.
Green circles indicate valid Lowered values.
