The 3D DXF contains the rebar cage as extruded prisms on separate layers. The 2D DXF is the dimensioned fabrication sheet with bar marks and BBS.

Cost-drivenSection options
Same loads, optimised reinforcementSections are searched downwards from the entered size in 25–200 mm steps, not below 300 mm (IS 13920 Cl. 7.1.1). Moments are held constant, which is conservative: a smaller, less stiff column normally attracts smaller analysis moments. Re-run the frame to confirm.
