I am having problems with the location of .ctb files in different drawings. I can open one drawing for printing and it show a list of .ctb files, then when I open a seperate drawing it shows a completly different list of .ctb files. Is it just a matter of setting the options settings correctly so they all read to the same place? Why would there be multiple locations of files?
to add to Murphs comment, you can use the CONVERTPSTYLES command to flip a drawing from looking for .stb files to a drawing that will look for .ctb files.
