Archicad 25 Stair


I am creating a custom stair on a project and was wondering if there is any way I can start the stair with a custom shaped landing. The stair is coming off a deck and and I would like to know if I can edit the shape of the first step. Any help is appreciated. I am attaching a screen shot and like you can see there is part that is overlapping the deck and I would like to eliminate that by customizing the shape. (Highlighted the shape I want it to be)


If you solution includes creating a slab as the first step and then starting the stairs, sorry but that is not what i am looking for. 


Thank You

A small box with the label Edit should pop up near your stair when you select it. When in Edit Mode you can select the landing and change it's shape much like you would a Fill. Do note though that this does not change the shape of the structure. In your case, the excess structure could be SEO'd away.

This is probably not the perfect solution that you want, but it gets you what you want with the one stair.



You must start your landing at right angles to your decking as the starting nodes of the stair can only be made wider/narrower.

Then select the boundary of the stair (not the baseline), and you can stretch the nodes to form any shape you want.
