How detailed does it need to be?

You could always model a elevating slab array and yank them into place....... the 3D profiler would make a handrail, nore-or-less.......

Thanks for responding. I'm not quite sure how to do what you just suggested. Could you walk me through it? The height of the stairs needs to be +12'-6" from project zero, width of the stair 4', rise" 6" run 12".

three phases:

The layout:
- work out the plan array of the stairs - use lines arrayed from the centroid of an ellipse - this is plain drafting.

The vertical displacement:
- make a tread from a slab to your thickness and multiply the slab with vertical displacement equal to your needs - make a straight run - spin them around the center of the ellipse in a circle....whatever.

Put them together:
-- drag the stepped slabs into the array one at a time, and resize them.

Do the flights as one stair each, landing as a slab, group.

Or, when finished, save as a lib part. That is, if you expect no changes (ha!).

Also, try ArchiStair ...
