Fast way to make purlins and creating untypical roof layer

[Anonymous]

Hi guys, is there any fast way to make purlins like I marked on picture and later, how to creat roof layer? (some sheet, insulations and cover)

My way in doing these elements is using Roof by Extrusion and walls as helpers for beams and purlins :

1. In a floor plane draw a vertical Reference Plane and name it , so to can be used as Work Plane
2. In an Elevation View , paralel with the Reference Plane created in step 1 , make a Roof by Extrusion, drawing an open curved profile - adjust the length of the extrusion
3. in the Level below the Roof , draw walls at a distance you want to place the curved beams ( you can use array in order to be able to play with the distances) - these walls are use only as helpers and can be later errased.
4. attach the walls to Roof : select wall >Attach Top/Base - attach Top....
5. create curved Beams: Structure > Beam (Load one if it is not already loaded)> activate 3D Snapping and Pick Lines  - pick on the curved intersection line between the wall and the roof underside
6. as for the purlins , use Structure > Beam System > check in Properties >Costraints >3D and Pick Supports -pick the curved Beams made in step 5
7. Finally you can errase the walls...

The method Constantin shows is the best way, here is a screencast i done last month for the same issue.

And as Constantin said, use a "Roof by Extrusion" for the curved roof, drawn in an Elevation/section

Hope this helsp

I am facing issue in aligning the purlins according to the curved beam. How can i resolve it
