Collar beam
It’s been developed to define collar beams between rafters. Collar beams can be
defined as single or double. To define collar beam:
Click Draw/Roof/Collar Beam.
Left-click on one of the rafters that the collar beam will be drawn in between.
Left-click on the other rafter that the collar beam will be drawn in between.
The Collar Beam dialog will appear on the screen. Do the necessary settings here and click OK.
The collar beam drawing will be completed.
Right-click and click Repeat Last Command from the appearing menu.
The program will re-enter the collar beam drawing mode.
Generate the other collar beams applying the procedure above.
The parameter in the collar beam dialog are the following:
Width: The width of the collar beam cross-section (m).
Height: The height of the collar beam cross-section (m).
Elevation: Enter the elevation (m) that the collar beam will be placed. The distance of
the collar beam from the eaves is determined automatically.
Distance: The distance (m) between two collar beams in case of double collar.
Trim Distance: Determines the distance (m) of the diagonal trims to be applied to the ends
of collars. Negative or positive value can be entered.
Create Left/Right Collar: If double collar is wanted check both choices. If you want single collar
check only one choice.
