What the product does
It converts pitch representations, solves supported right triangles, calculates common-rafter line geometry, converts compatible plan area to sloping area and applies visitor-controlled material assumptions.
Every result exposes inputs, formula, units, assumptions, rounding and safety boundaries. Core tools work without an account.
What it does not do
These calculations describe geometry only. They do not size rafters or trusses, assess loads, approve a design, interpret building codes, specify cuts or fasteners, or guarantee material quantities.
