For the moment only a few parameters are schedulable. However as Autodesk continues to fail in implementing proper material take-off for stairs, one needs to resort to using parameters. Alas, here Autodesk fails again.
Sure you can conjure up some formules using Riser Height, Tread Depth and Run Width. But this doesn't take into account any overlaps, and is pretty useless when modelling a winder staircase.
We need to be able to schedule ALL parameters of a Run/Landing so we can derive the quantities using formules.
Even better would be the ability to get proper material take off from stairs/run/landing, this Idea already exists.
