In the image below, notice how the beams were added between all columns, walls, and other
supporting beams. The pre-existing beam was not cut by the beam perpendicular to it.
When Revit Architecture places beams along a grid line, it uses the following conditions:
■ All the possible supports that intersect the grid line, such as columns, walls, or beams, are scanned.
■ If a wall is on the grid line, a beam is not placed in the wall. The ends of the wall are used as support.
■ If a beam intersects and crosses the grid line, that beam is considered to be an intermediate support,
because this beam supports new beams created on the grid line.
■
If a beam intersects but does not cross the grid line, this beam is supported by a new beam created on
the grid line.
For more information about beam structural usage, based on which elements are being created, see Structural
Usage of Beams on page 770.
Sketching Beams with the Chain Option
When the chain option is selected, Revit Architecture supplies the endpoint of the last beam as the start
point of the next beam.
To sketch beams using the chain option
1 On the Structural tab of the Design Bar, click Beam.
2 On the Options Bar, check Chain.
3 Place the first beam in the chain, see Sketching Individual Beams on page 772.
4 Place each additional beam(s) by clicking the end point(s) of the beam.
