Getting started with Blender’s BMesh API

Salai Vedha Viradhan has published two articles that introduce the BMesh API, a module containing Blender’s internal mesh editing tools. The two-part crash course demonstrates how to use BMesh API to create a spiral staircase.

Part 1 focuses on an introduction to BMesh, understanding the geometry of a spiral staircase, and generating a single stair using various mesh operations. Part 2 covers replicating the stair and creating railing and balusters, using Matrix transforms and translations.
