Add a Primary Beam

This function can be used to add a primary beam to the framing. The vertical position of the beam is determined by that of the framing. The beam is a separate profile that is not attached to the framing. The beam is only attached to the framing when you add it to the edge of the framing in such a way that the beam is inside the framing (not under it).

Select the cross section and add the primary beam as you would a normal beam, see Add a Beam. However, the parameters of a beam added under the framing are different from one added as a profile. You do not type a vertical position for a beam added under the framing, but its position is tied to the top or bottom surface of the framing.

1. Select the structure. The basic layer of the structure will be automatically selected. If necessary, you can select another layer which defines the height of the beam.

   • Perpendicularly to the Roof Plane

     

6. Select one of the following as the locating point for the cross section:
   • Beam Right Side
   • Beam Middle
   • Beam Left Side
   The left and right side are defined by viewing the cross section from the start point of the beam towards the end point.
7. Select the start point of the beam.
8. Select the end point of the beam.
