Howto - spiral stair with center column?

[Mats_Knutsson]

Like any Weland fire escape stair for example...
How do we do it with 21?
Cheers,

I once made a spiral stair out off morphs with a handrail (spiral) from the library.

I just watched an interesting video by Eric Bobrow the other day where he made a custom spiral staircase.

Using non-custom components will be a bit easier.
It really is as easy as getting the settings you want then placing a stair using one of the arc options in the pet palette.
A couple of clicks and I had this (no centre post - that is just a column).
