Command -  


The Purlin on top of Beam connection connects the purlin to a roof beam or rafter.


This command can also draw stays between the rafter and the purlin. The purlin can be a lipped channel or Z shaped.

Selection order

First select the rafter, then select the purlin on the side where the bracket is to be placed.


When selecting the profiles to be connected, Parabuild will automatically filter the proposed connections.

The filtering will not only be based on the profile types, but also their orientation with respect to each other. For example, Parabuild will recognize if a beam is connecting to a column flange or web. This information is used by this command to filter out the incompatible connections in the connection selection dialog.

Therefore, the presented options may differ from those illustrated here.
