Uniform load added. Snow load could be added at the same way.

Want to add wind load, but have no idea how to caculate it.

Trusses to cover an area, both ends are gable end. All trusses are the same.

I'm wanting to build some steel trusses in FreeCAD and ensure the design will not fail. The designs I like are the attic truss and the three-piece raised centre bay truss. If I design these in FreeCAD, can it calculate moments, stress, etc. and solve like other tools?

Frame3DD can do the calculation.
