4. Measurement & Onshape

TAS2O :: CAD

Measure before modelling

Use millimetres, rulers, and calipers to turn a physical requirement into dimensions and constraints.

Model with intent

Build sketches in Onshape, apply dimensions and geometric constraints, then extrude a manufacturable part. The goal is not simply to make a shape look correct on screen, but to define why it has that size and geometry.

Evaluate

Compare the finished model or part with the original measurements and design requirements.
