A look inside the app
Why professionals use it
The formula stays visible
Weight results show the expression they came from, so you can check the section dimensions rather than trusting a number.
Joints, not just sections
Weld, bolt and rivet strength calculations for fifteen joint types — the part most weight calculators leave out.
Custom materials
Add any alloy with its density and it behaves like a built-in material across every shape.
