This Revit software tutorial shows how to array a series of voids to create a changing truss system. Rather than thinking of the modeling in components what we are doing here is modeling a solid and using Revit's cut geometry tool to slice a solid into stick members. The only catch to this techniques is that each truss has a slight slant on the top and bottom. This is something we can look past since it will be lost in the line weight. Once this model needs to transfer to a higher lever of precision one should consider another modeling technique. As a design tool this technique allows for quick iteration while maintaining the design intent. Learn how to build a parametric canopy truss system in this intermediate level Revit tutorial.
