Propagate rebar in Revit

00:03

In Revit, you can copy and adapt shape-driven and free-form rebar from a source host to destination hosts.

00:10

The bars are adapted by matching the rebar constraints.

00:15

The bars are aligned automatically by host, or manually by the source and destination faces.

00:21

To begin this exercise, select a host with rebar inside.

00:26

Then, on the Modify | Structural Framing contextual tab, in the Reinforcement panel, select Propagate Rebar.

00:34

With this tool, you can align the rebar automatically by host, or manually by the source and destination faces.

00:42

For this example, use the manual method.

00:45

In the Propagate Rebar panel, select Align by Face.

00:50

Select a face from the source host that already contains rebar.

00:54

Note that the rebar is aligned with respect to this face.

00:58

Then, select the destination face on the target host.

01:02

The rebar appears as a preview for the faces you selected.

01:06

Finally, click Finish to save the propagated rebar, or click Cancel to discard your changes and exit the Propagate Rebar command.

01:15

Be aware that after rebar elements have been propagated, there is no connection between the original and propagated rebar sets.

01:25

Also, if some constraint targets are not matching, such as the faces of the original and destination hosts not being parallel,

01:33

then those constraints are not applied, and some bar segments will stay in place and not adapt.

Knowing how to propagate rebar from the source host to destination hosts in Revit helps with the success of every building project.
