A metal railing that could be used as safety barrier.
A complex picket fence assembly.
Here is a great rail line assembly shared by Garth Kay-Hards complete with materials.
This is one of several great assemblies recently shared by Pippa C. The assembly includes a 2×4 chamfered timber top rail, 1″ metal rod for mid bars, posts with timber accents and bolts.
It is so easy to share an assembly on the 3D Warehouse. Just build an assembly in SketchUp, make it a component, and then right-click 3D Warehouse->Share Component. To help other PB2 users find it, be sure to tag the model with the words ‘profile builder’ and ‘assembly’.
