i have been designing carts made of structural steel, but when i use my weldments the only thing i have to choose from is 2 x 2 x .25, and 3 x 3 and 4 x 4, but i have a need for 1 x 1 x .125, and 3 x 6 x .25 and a few others where can i get the info to create these parts and put them into the library where i can access them along with the other parts that i use. not sure if it is clear what im trying to do but i hope. i have the 3d sketch jsut need the to get the right call outs on the cutlist and others.SolidworksWeldments
