CAD Foundations: Spatial Thinking and Drawings

Before you open any CAD software, you need to think in three dimensions and read the language engineers use to describe parts. This primer builds the spatial-reasoning and engineering-drawing fundamentals every FRC designer needs: coordinate systems and views, orthographic projection, and how dimensions, tolerances, and units turn a sketch into a part the machine shop can actually make.

CAD Foundations: Spatial Thinking and Drawings is the prerequisite module of the CAD & Design guide — the ground the 7 numbered modules after it assume you already have, and Getting Started: CAD Software and the Design Process follows it. It holds 3 of the guide's lessons.
