SketchUp Speed Modelling: A Simple Spiral Staircase [updated]

I supposed spiral staircase is one of the most popular subject in 3D modelling tutorials, however, for all the models I've done, spiral staircase is not in the list.

This is a simple spiral staircase -- with chequered plate treads welded to tees, which in turn are welded to a circular hollow section post. Balusters and railing are of circular hollow sections, too. I supposed the post should be mounted on a base plate that is bolted to a solid base.

The principle modelling process took less then 30 minutes to complete. The model of this staircase can be found in 3D Warehouse, as below.


Updates: I made an animation with this model, on this page.


  1. Great post! I have always enjoyed spiral staircases ever since I was younger, especially 3D ones. Thank you for sharing this with us!

  2. Thanks, guys, I'm glad you like the model. :)
