Autocad Mechanical 2005 (Inventor Series 9) on Win2k, SP 4. I use stb's for plotting, but everyone else still uses ctb's. I know I can create a new stb from the ctb used in a drawing, but thats dumb. What I want is to switch a ctb drawing to the stb I normally use, not some new stb created by convertctb. Is there a way?
