Calculation reference / 30 tools
Follow the measurements through the calculation.
Each tool links to its standalone formula record or its own method and limits section. Shared arithmetic records cover more than one tool where the calculation actually overlaps.
Formula versions and change history →Railing layout
Work from a clear opening, post-centre runs, or the complete guard outline.
Deck surfaces and finishes
Plan walking boards, exposed edges, grade-following skirting, and wood finish coverage. The finish tool also handles fence components.
Fences and gates
Choose a material system, then check post layout or a measured gate opening separately.
Concrete and aggregate
Take off supplied hole or slab geometry, compare fill orders, or count products for prescribed joints.
Yard and landscape
Measure a footprint, count patio or bed materials, transcribe wall courses, or take off an already-designed ordinary yard drain.
Shed and roof
Compare shed support paths, check equipment entry geometry, or count covering across measured roof planes.
Interior finishes and insulation
Lay out drywall on measured surfaces or plan an insulation layer from climate and existing R.
Stair layout
Reconcile whole risers, treads, and a reviewed stringer profile before planning stock.
Construction measurement
Measure surface coverage and bulk layers before choosing material orders.
