Steel cross and purlin problem

[mert_01]

Good work. I can't throw steel cross and purlin between the scissors. When I want to cross it, the element is formed in a different way. I am also open to different modeling methods for the project.

Hello there; 1- The ridge area and heights of your truss located on E - 2 axes are incompatible with other trusses. Therefore, it is normal that your cross and lovers do not form correctly. If you need to use the scissors in this way, you should use the single purlin and single cross commands. However, since it does not make sense to use it in this way in terms of the continuity of the structure, it is arranged in accordance with the ridge area and height of your other trusses. 2- In crosses that must be entered with the multiple cross command you use in the roof, V or Inverted V is not used as a type. You need to edit as type X. 3- Since the total length of your scissors has changed, you must enter the purlin as a group for the regions similar to the purlin command, and then enter the data with a single purlin for the remaining regions. Good work.
