AS/NZS 3679.1 Grade 300 · I without fillets. Mill tables govern.
Dimensioned drawing
310UB46.2 · 45.7 kg/m · I without fillets
STEP is a 1000 mm faceted prism of the mill outline, including the flange-to-web radius (8 points per 90°). I and A are still without fillets — mill tables govern. DXF is the same 2D polyline.
