You can use Weldments to create a structure as a single multibody part.

You use 2D or 3D sketches to define the framework, and then create structural members containing groups of sketch segments.

You can use other Weldments tools to add objects such as gussets and end caps.

You can add weld gaps and beads to the model.

You can create drawings to document the design, including tables of cut materials, cut length, and weld bead totals.
