I am looking for some simple 2D CAD symbols for a layout in a metal fabrication shop. I want things like press brake, shear, bandsaw etc. I want to try a changed layout and would like the items to be able to be identified as to what they are. I can just use rectangles but that makes it hard to visualize. The symbols do not have to be exact and I can rescale them to the proper size. Free would be great.
