simple stair winders

[Anonymous]

I'm a new user trying to create a simple stair as shown in the attachment using stairmaker but I haven't found any combination of settings that does the trick - the winders always continue around the square landing area and won't meet at a single point.

I found an old post that indicated stairmaker just wasn't able to do this but since it was from 2004 I wanted to check in case there was an improvment made since then that would help.

I'll get archistair if needed but I was hoping to put it off a little longer as I just spent a good deal of money to by AC...

any help appreciated!

Here in NZ the going or tread is measured at the walking line,which is 450mm out from the stringer. So that stair is legal here. Makes sence as you cant walk hard up against the handrail any way.

Does the Stair still have to have a Minimum Walking width that does not include the 450mm?

The tread depth shall be measured horizontally between the vertical planes of the foremost projection of adjacent treads and at a right angle to the tread's leading edge. The greatest tread depth within any flight of stairs shall not exceed the smallest by more than 3/8 inch (9.5 mm). Winder treads shall have a minimum tread depth of 10 inches (254 mm) measured as above at a point 12 inches (305) mm from the side where the treads are narrower. Winder treads shall have a minimum tread depth of 6 inches (152 mm) at any point. Within any flight of stairs, the greatest winder tread depth at the 12 inch (305 mm) walk line shall not exceed the smallest by more than 3/8 inch (9.5 mm).
