unequal pitch · cuts only
Use like any calculator: check before you cut. Setout is a calculation aid for conventional equal-pitch cut roofs. It does not size members — spans and sizes are per AS 1684, your engineer or your truss designer. Verify all dimensions against the job before cutting; no responsibility is accepted for reliance on the output. Complex multi-wing shapes are beta — eyeball the 3D for completeness before trusting the cut sheet.
