Not sure what your skeleton contains, but we use ours to create 2d or 3d surfaces with all the details (i.e. holes, bend, rounds). This way you can see your "assembly" of parts before you actually create the .prt or .asm files. To create a part just insert copy geom surface quilt) from skel at the default location. If the quilt is 2d you can thicken it. If it's a sheet metal part you can then assign your first wall and flatten it. If it's 3d just solidify it. Then in your assembly simply insert all your parts one by one at the default location. Simple, no dependency btw parts... Good luck
