Does anyone know what the values for the parameter ifc_StairType are? I know it is an integer, and is now par of any object that is a Stair Type. I want to know what value to place there for the custom stair I have created, but this appears to be undocumented.
With door type objects there is a similar parameter; ifc_optype. Luckily the built in doors have a another more descriptive parameter ifc_optypestr that give a description to the integer value. No such luck on the stair though.
