Managing HTML Templates in the <Windchill>/codebase/templates/ Directory
The HTML template files are located in the <Windchill>/codebase/templates directory. These files must be in this directory at runtime. If you want to modify any of the files in this directory, be sure to put a copy of the corresponding PTC files (before you make any changes) in the <Windchill>/wtSafeArea/ptcOrig/codebase/templates directory. Then modify the files and put a copy of your customized files in the <Windchill>/wtSafeArea/siteMod/codebase/templates directory. For details on using the <Windchill>/wtSafeArea directory, see Setting Up a Directory Structure for Managing Customized Files and Text Tailoring.
