Description
A span symbol – the Z-shaped span break with long diagonal strokes used on structural drawings to indicate member spans and direction. Drawn as a block so every span mark on the framing plan is identical in weight and angle.
Use it on framing plans and roof layouts to mark joist, rafter and sheet spans, paired with the span direction text convention your office uses. It joins the structural symbols and annotation families on this site. A free DWG format download for AutoCAD and compatible software.
