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). <BR /> <BR /> My second question is: Can I build a curved handrail? I didn´t find it in basic ArchiCAD 16 library.<BR /> <BR /> Thanks for help</T></DIV> Thu, 31 Jan 2013 19:50:55 GMT Anonymous 2013-01-31T19:50:55Z https://community.graphisoft.com/t5/Libraries-objects/Changing-materials/m-p/218236#M14005 <DIV class="actalk-migrated-content"><T>Hi, I´ve built a spiral staircase.
