Roof design in Revit®, whether steel or timber, poses certain difficulties to this day. It’s a process requiring high precision from the designing, drawing, and manufacturing points of view. On top of that, mistakes can easily sweep into the project at any stage. The continual advancement of modeling software brings much-needed speed and efficiency for architects and structural engineers. But how can we ensure smooth sailing right from the concept stage through to technical documentation and manufacturing? The key in every BIM or standalone project is to lay a solid foundation, i.e. to produce a rigid geometry using proper modeling techniques and have sufficient understanding of Revit’s functionality.
In the case of roof design, it’s important to model the roof in line with native Revit rules and constraints. For example, modeling a roof by picking already-existing walls is the best way to go (if possible – sometimes it's not).
