HOW FACTORYSPEC WORKS · UPDATED 10 OCTOBER 2026
Cut lengths and panel sizes from finished dimensions
Common made-to-measure mistakes are simple ones: a deduction applied twice, a size measured to the wrong edge, or a rounding nobody agreed. FactorySpec makes each of them explicit.
Name every kind of size
Ordered, finished and cut sizes are separate, named values in the model. A deduction turns one into another in one place, and the model is checked so that it cannot be applied twice.
A worked example
“Horizontal rails are the finished width less 40 mm.”
An 800 mm wide frame gets two rails cut at 760.0 mm. When release 2 changes the deduction to 42 mm, new units get 758.0 mm, and units accepted under release 1 keep 760.0 mm.
Exact units and precision
Inputs can be entered in millimetres, centimetres, metres or inches, converted at exact factors. Each input has a precision, such as 0.1 mm. A value more precise than that is refused, with the original shown, never rounded to fit.
Rounding only where you say
Calculations are exact. Rounding happens only at a step your model declares, to a stated increment, half away from zero, down or up, and the trace keeps the value before rounding.
What the result carries
- Linear parts: a cut length in millimetres.
- Sheet and panel parts: width and height in millimetres.
- Counted parts: a whole count, with no size.
Lines combine only when the part, revision and size are identical. Two rails of different lengths stay on separate lines, even with the same part code.
What it does not do
- Nesting or optimising cuts from stock lengths or sheets.
- Turning panels into area, or parts into weight.
- Producing machine files for saws or routers.
Those stay with your cutting and machine software, which can work from the sizes FactorySpec calculates.
