Circular Stair Construction

GFBArchitect

When I build stairs, the part that checks the stairs by adding two risers and one tread to let you know if you are "out of range" doesn't let me build a legitimate stair. On a circular stair, the treads need to be 10" min along a circular path, 12" in from the inside of the circle. The risers can be no more than 7.75". The narrowest end of the tread has to be at least 6" deep. But when I input the numbers correctly, it says "out of range" and stops me from building it. Can this feature be overridden somehow? It would be a better stair builder if it were left to the Architect to make sure it meets code as codes are often revised. Thanks for any help.

You should be able to change the value in that weird two and one parameter so that it doesn't constrain you from doing what you want. It's been a long time since I've used the stair tool though so my memory may be a bit fuzzy.

Thank you. It does work if you mess with it enough.
