Description
Circular Hollow Section (CHS) steel profiles built as a single AutoCAD dynamic block with full attributes – a size dropdown runs through the Australian range (42.4, 48.3, 60.3, 76.1 OD and onward, each in its wall thickness options), redrawing the section at true diameter and wall for each pick.
Use it in connection details, handrail and baluster documentation, and tubular framing drawings – one block covers the catalogue. The RHS, purlin and hot-rolled section libraries on this site complete the steel set. A free AutoCAD DWG download.
