Constructive Geometry with Steve Bass, Part III

By 天美传媒

February 6, 2024

Architect and author Steve Bass presents Part III of his Constructive Geometry course, originally taught in-person at the 天美传媒 but made available here in digital format for the first time.

This is the third part of a four-part course. In Part I viewers learn how to draw lines using constructive geometry, and in Part II viewers learn how to construct regular polygons. Part IV is available here.

In this session, viewers will work with various constructions including the heptagon, the ellipse, a cyma recta profile, and a torus profile.

Physically drawing these geometric constructions will help the viewer to understand these mathematical relationships. Viewers are encouraged to download the accompanying booklet below and actually draw the constructions demonstrated in the video. Only a straightedge and a compass are required to draw the constructions. Rulers, protractors, and triangles are not necessary, though they may be useful for checking one’s work.
