Description
Rectangular Hollow Section (RHS) steel profiles built as a single AutoCAD dynamic block covering the full size range – a Section dropdown switches between every standard Australian RHS from 50 × 20 × 3 up through 150 × 100 and beyond, redrawing the profile with true wall thickness and corner radii at each selection.
One block replaces a folder of section drawings: set the size, place it in the connection detail, and the geometry is right. The UB, UC, PFC, EA and purlin blocks on this site complete the steel library. A free AutoCAD DWG download.
