All buildings have roofs and roofs with big spans are not so rare. To cover such roofs, we usually use trusses. They are easy to assemble, require less material and solve problem of big gaps between structural supports.
While engineers work with Autodesk® Revit® they have a possibility to insert Truss families, but this process is not the best thing you can experience in your life. Sample truss families can help you in only very standard situations, but if you need to model different shapes of trusses with different top and bottom chord lines, then you’ll have to work many hours on preparations of new parametric families which will also be a big headache unless you don’t need to do this every day.
That’s why we create special tools for roof framing- to reduce stress and improve efficiency of engineers’ work. In our framing packages for wood and light steel gauge structures, we have BIM solutions Wood Framing Truss+ RT and Metal Framing Truss+ for truss modeling. Our applications support engineers with a pack of tools to automatically create/update roof truss systems, adjust them to the roof shape, cut/cope elements, create assemble drawings etc.
Within our solutions for wood and steel truss modeling we have one powerful tool Truss Builder, which should be discussed separately. Truss Builder lets you create new truss type using model lines and roofs. Procedures are as follows:
