Changing materials

[Anonymous]

Hi, I´ve built a spiral staircase. I need to change the material but ArchiCAD doesn´t allow me to change these materials (it is set to wood but I need a concrete).

My second question is: Can I build a curved handrail? I didn´t find it in basic ArchiCAD 16 library.

Thanks for help

You've built the stair using the fill conversion method?

See the attached for stair parameter settings.

For a curved handrail not associated with a stair, try a ramp object.
