TOPIC:

There are some spiral staircase objects in the object catalogue Objects / Component / Stairs/

With Visual Building Professional/ Premium, you could construct a spirial staircase using the same methods as described in the Training Course and in this topic . The spiral staircase would be easier because all steps would be the same size.

With Visual Building Professional/ Premium, you could also import a 3ds model of a spiral staircase. This includes any object created in Sketchup, which can be converted to 3ds.

How can I add a spiral staircase?
