Engineering guides

Engineering fundamentals & practical design

Where college theory meets real design work: drawings, tolerances, assemblies and getting parts made.

How to read an engineering drawing

A practical guide to reading a mechanical drawing: projection and views, line types, dimensions and symbols, the title block, and a step-by-step method with a worked example.5 min read

Tolerances, fits and GD&T basics

Why every dimension needs a tolerance, how ISO fits such as H7/g6 work, how tolerances stack up in an assembly, and how to read the basic GD&T symbols.6 min read

Design for manufacturability (DFM): rules that cut cost

Most of a part's cost is fixed by its design. These are the DFM and assembly rules for machined, sheet-metal, moulded and printed parts, with a worked sheet-metal example.5 min read

Assemblies and bills of materials (BOM) explained

How CAD assemblies are built from parts and mates, how assembly drawings and exploded views are laid out, and how a bill of materials is structured and used.5 min read

How a CAD model becomes a physical component

The full route from a 3D CAD model to a finished part: checks and analysis, drawings and export files, CAM and manufacturing, inspection and release, with a worked example.5 min read

From engineering drawing to 3D CAD model: a practical guide

A step-by-step method for turning a 2D engineering drawing into a clean, accurate 3D CAD model: reading the views, planning the features, sketching and checking.5 min read
