Does anyonew know where I can find an add-on application for AutoCAD 2000, or AutoCAD 2000 LT, that draws Sheetmetal Ductwork and fittings?? I'm used to drawing with the Quickpen 3D CAD Sheetmetal program and drawing in AutoCAD is just like the old days of drafting boards and 2H pencils -- VERY time consuming. A shareware program would be great, or one that doesn't cost too much. I've searched and searched and am at a loss. I did find MECH-Q, but it had bugs and wouldn't work. Any help or ideas would be greatly appreciated. Oh and not metric, but...
