Copy and adapt free form rebar from the source host to destination hosts. The bars are adapted by matching the rebar constraints.
If some constraint targets are not matching (for example, faces of the original and destination hosts are not parallel), those constraints are not applied, and some bar segments will stay in place and not adapt.
When you propagate rebar from a source host to destination hosts, you can choose to align by face or by host using the new commands in the ribbon.
To propagate rebar
Reinforcement panel, click
(Propagate Rebar) .
Propagate Rebar panel, click either

Show Tooltip panel, click

(Finish) to save or
