I have an octagonal shaped room (silo, 3 stories tall) and I need to build a stair case along the outer wall, following the shape of the octagon, with winders in the corners. What is the best way to go about doing this? I can't seem to figure out how to get the angles correct, the railings to work, get it to create winders on the corners, or get it tight to the wall.

I'd do some layout with CAD lines first.


I've posted a tutorial on stairs in Tips & Techniques that may help.


Easier to do in a larger space, I think.

I would also add that what you have done, at a glance is not workable. I have done lots of stairs but not exactly what you are now trying to do. You need to reduce the number of treads between winders so they geometrically fit together more symmetrically. You have set yourself a difficult task but I believe it is doable. Laying out with CAD as Eric has suggested will tend to show you what they should look like to use as a guide to edit the actual stair objects. This will have to be precisely done in order to control the winders. I think if I were to attempt this, I would NOT use the automatic winders but just make all of my winders manually and manually set their heights (I can control what I do manually but auto-winders are not precisely controllable).

      1) Finished floor for this existing building is 36". The driveway in back is level with finish floor also. I cannot get the landscape all around to fill in under building and driveway. The drive slopes up to flat across as much as I have flat. The exist. H.C. ramp goes into a concrete porch. This is as-built plan and then I will design a restaurant on the first floor. 
      2) I cannot get u shaped stairs to work and land on the 2nd floor by the entry door.
      I would appreciate any help in accomplishing what i need to do.

      Hello, I need help creating this specific balaced stair in chief architect premier x12. 
      The only thing i could think of was to manually create every step from slabs. I still need to corect some steps from plan view but at least the height and length are good - now how can i add the rails on the inside and outside walls?
      Or maybe is wrongfully thought from the start; what is the simplest, smartest way to create this type of stairs?
