Step 7 : create the truss beam
In a new sketch created in the YZ plane, and after making the "SketchRoof" master sketch visible, create a carbon copy of this master sketch, then fit it to the outline of the truss beam.
Create a symmetrical extrusion with a length equal to the thickness
of the truss beam

In a new sketch created in the YZ plane, create the geometry
of the
tenons of the truss beam.
Create a symmetrical extrusion with a length equal to the thickness of the tenons
(30 mm)
