I'm new to the stair tool. I've been trying to use it in landmark for external steps.
If the tool can only offer basic functionality in terms of two elevations and calculating riser heights and tread depths, please can you add a feature that allows you to calculate a fall across each tread.
If it could be all singing and dancing, it would be great if you could specify tread make up a bit like a slab, and risers as a wall, so you can put a section through and get the construction...
