What this workbench does
Find a uniform scale factor and predict all three output dimensions from one target dimension.
It combines an editable calculator, baseline comparison, one-input sensitivity chart, transparent formulas, worked examples and a printable measurement sheet.
How to assess the result
Measure the feature that matters for fit and recheck tolerances after scaling, especially holes and snap-fit details.
The calculations implement the stated geometric or arithmetic model. They are estimates where real materials, equipment or processes differ from that model. The specific assumptions are listed on the calculator and reference pages.
