Each formula is linked to the standard and clause that governs it, visible inside the calculation.
Built-in materials and sections
Steel, timber and concrete properties are built in and tied to the applicable standards.
Change material in one click
Swap timber for steel, concrete or cold-formed steel with the same inputs and design criteria.
