Really basic stairwell absolutely refuses to make right angle

Stairs tool won't under any circumstances let me make a third right angle here. I've changed the settings in every way I can think of with no change.

Hi cetempleton,

Just to note, you may want to only set the bottom and top linked story, width, and the rise and run to get a good result. I ran a stair with your overall measures at 5' wide and approximate 38' total rise in my test building (vs your approx 40'), using 7" max rise and 10" max run treads. I used your max footprint (see as trace in snip) and started at the bottom and went up.  Came up with just over 45 treads with an included intermediate landing as Barry suggested.  Seemed to work fine without overlap, so you may want to adjust your parameters and hopefully it will work out better.

 

If it helps, it took me some time with the stair tool back in 2021 to get predictable results.  So much so, for exit stairs, I keep a Favorite of a basic footprint graphic, a stair design with settings, and one of the railing design with settings.

Looks like your last landing snap is too short to make the 90d turn work.

It looks like you have locked your stair at 75 risers which means the end will overlap with the start, which Archicad will not allow.

If you can do the other 90° corners, there is no problem with your settings, it is just one stair can not overlap with itself.

You would have to break up that stair into 2 or more parts.

Also check regulations as you probably need a landing in the long flight on the right.
