WELDMENT IN SOLIDWORKS
Weldments functionality enables you to design a weldment structure as a single multi-body parts. You have different structure member ( rectangle tube, c channel, sb beam, pipe, square tube) You can use 2D and 3D sketches to define the basic framework in weldment. Then you create structural members containing groups of sketch segments.
Now with your weldment in the assembly and the other components attached, you need a Bill of Materials (BOM). It’s possibly to show the cut list for all the structural members in an assembly BOM. You will need to choose a BOM Type of Indented in the Property Manager.
