Modeling a spiral stair for architecture with Blender
In my classes about architectural modeling, one of the exercises that challenge most of the students is the creation of a spiral stair. No matter what software you use to create the 3d model, it takes some practice to figure out how to create this type of stairs. In Blender, we can use a mix of tools to create a spiral stair. In the tutorial below you will get to know how to create a spiral stair using an Array modifier and even create some railings for this model.
