Here are some new findings about modeling for architecture, with the objective of creating a spiral staircase in 3d. This time the tutorials use the polygon modeling tools of Maya, which just looks like other tools available in Blender.

There are two videos created by an artist called Hacobo covering the creation of two types of stairs. In the first one we have a spiral staircase, and on the second a regular staircase, with

Since this is the third tutorial about spiral staircases that I post here, and I believe that none of them were made specifically for Blender, it is time to create a tutorial about that for Blender. So, expect a tutorial on modeling spiral staircases with Blender this week.
