ChiefJoelJ Posted February 6, 2023 Share Posted February 6, 2023 I am trying to create a clear-span building that has girder trusses that support the roof. These girder trusses support a 3-piece truss-set perpendicular to the girder. I have no problem creating the girder truss, I just do not know how to make the top of the girder truss level with the top plate of the wall so the perpendicular roof trusses sits on the top plate of the wall and on the top of the girder. I have attached some drawings that I did in another CAD program just to illustrate the problem. Does someone know how to move the top of a girder truss down to the level of the top plate on a wall? I'm wanting to use Chief generated trusses if possible and not just polyline solid or something like that. Thanks in advance!!

Chopsaw Posted February 6, 2023 Share Posted February 6, 2023 Trusses require a ceiling and roof plane to build so you will need to provide those for the girder. Not really sure I understand the design concept or the reason for the 3 part truss but you can certainly draw it that way with Chief. Link to comment Share on other sites More sharing options...
joey_martin Posted February 6, 2023 Share Posted February 6, 2023 I would make the girder truss a symbol so that you can position it accordingly without needed to create extra ceiling planes. Open a blank plan and create the girder, turn it into a symbol if you can and bring it into your plan. Link to comment Share on other sites More sharing options...
AvoyeDesign Posted February 6, 2023 Share Posted February 6, 2023 You can edit a truss profile in a cross section view. Draw the truss, create a cross section, and then pull the bottom cord of the truss down to the top of the jack stud. Link to comment Share on other sites More sharing options...
GeneDavis Posted February 6, 2023 Share Posted February 6, 2023 Call me stupid, but why can't your girders be up in the attic with the other trusses, which are then hung to its bottom chord with appropriate connectors? I'd suggest you consult with a truss engineer before going further. Link to comment Share on other sites More sharing options...
