This reference and textbook on vectors and coordinates focuses on mathematics and programming solutions. As an easy-to-read work, it forms a practical collection on CAD faces, vectors, angles, normals, projections, rotations and more. Code fragments are written in CAD Lisp and therefore usable in programmes such as BricsCAD and AutoCAD.

The PDF can be opened or downloaded here.
