I need to build a girder truss; some of the intermediate members are HSS at 45 degrees. How do I creat that kind of steel section - the beam tool allows for changing the plane off of vertical but I cannot use it to get a 3D object that looks like a 4x4 HSS.
Of course you can if you use a complex profile for the beam. Or you can create a complex profile column/beam/wall (you choose) and convert to a morph and spin them any way you need. Or you can create the whole thing with walls in plan and turn to a morph or an object. Or find or make an object(s) that allows for what you need. There are many many ways to accomplish this.
