You can clear the print settings in a Vectorworks document by opening the document and by running the Clear Print Settings.vss VectorScript. To run the script, unstuff the file listed under the "Attachments" category below, and drop the script on the Vectorworks icon in the Dock. A VectorScript Message window will appear, stating "Script Complete." to indicate success. You can also run the script by selecting the Organize/Scripts/Run VectorScript... menu, and choosing the script file.
