Cut planning groups pieces that fit stock lengths, allowing for saw kerf. Reserve is added after cutting. The map is an estimate preview; check joint and installation rules.Worked example
Worked example using the form's default values.
Enter consumption, coverage, dimensions and pack sizes from the product label or data sheet. A preset fills editable fields; the calculation uses the values you enter.
The requirement includes your allowance. Purchase quantities round up to whole pieces or packages; purchase surplus is not another allowance to add.
The result estimates quantities. Check structural layout, system compatibility and installation in the design and manufacturer documentation.
Yes. Additional surfaces or sections are summed within the chosen scope. Do not enter the same element twice. Purchase different colours and products separately.
No. Amounts come from your inputs. Enter your supplier quote; a zero price omits the cost estimate and does not mean free material.
Calculate board rows, full boards and running metres including gaps and allowance. The deterministic model uses only explicit inputs and documented constants.
