3. Measurement & Onshape

TTJ3C / TTJ4C :: METROLOGY & CAD

Learn the inch system deliberately

Work with inch fractions, decimal inches, millimetres, and conversions. Automotive work often requires moving comfortably between systems.

Use real measuring tools

Measure thickness, diameter, centre-to-centre distance, fasteners, badges, bearings, hose, and other real objects with rulers and calipers.

Model from measurements

Use Onshape to turn measurements and constraints into a manufacturable part such as a personal marque badge.
