I am building templates for a fellow who would like to work in a CAD environment like his old office. He saved .dwgs from that office, and so I have the layers he is used to using. But he never saved the .ctb files to go with them.
Is there any way I can build a .ctb file from the .dwg? The dwg shows lineweights bylayer (default) and plot styles bycolor, so I can't simply test each layer for lineweight. Do I have anyplace to go with this?
