6 Specify offsets:
Then… If you want to…
enter a value for Start offset. A positive value shortens the
beam on its axis, while a negative value lengthens the beam
on its axis. offset the beam on its extruded axis at the start point of the
beam
enter a value for End offset. A positive value lengthens the
beam on its axis, while a negative value shortens the beam
on its axis. offset the beam on its extruded axis at the endpoint of the
beam
7 Enter a value for Roll.
This value specifies the orientation of the beam relative to its extruded axis in terms of degrees of roll. A
positive value rolls the beam counterclockwise when viewed from its end to its start.
8 Specify the beam justification, which positions the beam shape in relation to its extruded axis when you
draw the beam:
Then… If you want to…
select Baseline for Justify.
NOTE This applies to members created with styles from the
Structural Member Catalog only.
position the axis of the beam along the centroid of the beam
shape
select one of the 9 positions for Justify.
NOTE These positions are defined at a roll of zero, viewing
the beam from the end to the start.
position the axis of the beam along one of 9 positions on the
beam shape
