Creating Beams
You should add grids and columns before creating beams.
When adding a beam to a plan view, you must set the bottom clip plane below the current level; otherwise,
the beam is not visible in the view.
Add beams using one of the following methods:
■ Sketch individual beams.
■ Create a chain of beams.
■
Select grid lines that lie between structural elements.
■ Create a beam system. For more information, see Beam Systems on page 807.
Sketching Individual Beams
The Beam tool is the primary means with which you sketch individual instances of beams.
To sketch individual beams
1 On the Structural tab of the Design Bar, click Beam.
2 Load a structural beam family, if one has not been previously loaded.
3 In the Type Selector, select a beam type.
4 On the Options Bar,
■ click to set beam parameters.
■ click a value on the Usage menu to set the structural usage of the beam or leave it set to
Automatic
5 Sketch the beam by clicking the start and end point.
The cursor snaps to other structural elements, such as the centroid of a column or the centerline
of a wall, when you sketch a beam. The status bar displays where the cursor is snapping.
