Command -  


The Purlin on Beam 3-base connection joins 2 purlins or siderails at the center of the supporting beam or rafter.
It can also draw sleeves for the purlins and siderails, either solo sleeves or sleeves combined with brackets.

Selection order

First select the beam, then select the purlin 1 and then purlin 2.


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.
