In my project, I need to create a steel roof like the roof in the picture below, as you said, I created a base with the roof object, how do I provide the beam end joints, purlins (2,3 beam ends together), do I have to enter one by one with the stability beam while creating the rafter? When I do it, the top level of each rafter is different, so the same slope is not provided) How can I do it easily?
