Hi there,
I'm struggling with modelling an external spiral staircase with three landings (ground level, upper floor, roof).
โโ
Any idea how to approach it? Multistory doesn't work for with level differences (+0,000; +5,600; 12,000).
Thanks ๐
You can do 3 different spiral stairs stacked on top of each other. For the intermediate landings, one option is a floor thickness of the metal grate and have it supported by beams like your image shows. Or if it doesn't have to be that detailed you can just use a generic floor.
You might have an easier go it by modeling the first spiral flight (e.g. Level 1 to Level 2) by starting with a Center-End Spiral and then converting it to Sketch-Based and "fine-tuning" the sketch. Afterwards, you can Copy/Paste to Levels.
The logic is simple: a 5'-6" height and a 6'-6" height can only share a common riser height of 6". If your stair riser height is not 6" then one stair will not work. Just create two stairs and add a top landing by sketch for each.
