JTB DST Tool can merge, purge and convert Sheet Set DST files for AutoCAD, BricsCAD and any other CAD software using Sheet Set DST files. For example, if an item that is one inch long were inserted into a drawing set to millimeters, this setting would scale the item to 25.4 mm in length when enabled.
