11 Specify a value for Trim automatically:
Then… If you want…
select Yes. the geometry of the beam to be automatically trimmed to
any other structural members, other architectural objects, or
linework to which it is logically connected
select No. prevent the geometry of the beam from being trimmed
automatically
select By Style. use the trim setting from the beam style
NOTE This setting affects only the structural member being added. Adding a new structural member will not
change the geometry of an existing structural member, regardless of the setting for Trim automatically.
12 Expand Dimensions.
13 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
14 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.
15 If Layout type is Fill, and you want beams to be added to the selected edge of a column grid, slab, roof slab,
or wall at an angle other than the default of 90 degrees, enter a value for Angle relative to selected object.
16 Select a Layout type to specify how a beam is positioned in relation to a highlighted edge of a column grid,
slab, roof slab, or wall:
Then… If you want to position the beam…
select Edge for Layout type. along the highlighted edge of the object
select Fill for Layout type. within the boundaries of the object (from one edge to an
opposite edge or edges)
17 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
