Spiral Stairs Video By Yusuf

Yusuf,

I've got a stair that has eleven, 30 degree segments or 330 degrees total.  I can get it to work, but making minor changes can be disastrous.  I'll play with it more, but is easier and more reliable to use Joe's method for now.

 

It would be good to be able to specify the degrees of rotation, and the diameter and have them lock.  The segment and the total degree rotation are controlled by the tread depth at the walk line, the stair width, and the number of treads.  It's quite difficult to keep all of the variable under control.

 Bill I suggest your base line for this should be a cad circle having the diameter of your spiral stair changed to a polygon having twelve sides. Since chief is calculating the thread depth around the centre no need to consider, just fix your number of threads and snap the edge of your 12 sided polygon.

I am not sure I exactly understood your point.
