DXF to VRML97 is a utility that enables you to convert DXF files to VRML97 by simply dragging them onto the application icon. It is based on the dxf2vrml example program in Systems in Motion's open source DIME library. I have modified dxf2vrml to generate VRML97 code (instead of VRML 1.0), to handle multiple files, and to place new files (appropriately renamed) in the same folder as the originals. The DropUnix library from Zen Spider Software has been used to provide a more Mac-like user interface
