I don't undertand why the problem of cutting ramps in plan haven't been fixed yet! We are tryinf our best to use Revit and we`re hopping Autodesk is doing their best! The Ramp problem is a HUGE problem and is a old problem! Please Autodesk!! What are you waitting for? Deffendig Revit is a hard task with problems like that! I'm dealing with these problem since the 8.1 version! Come on!! We need ramps to be cutted in plans lust like stairs!
