This Wizard allows you to scan your drawings for a specific text string, and report all occurences of that text to a text file.
The Search string is Case Sensitive, and you can use wildcards like * and ?.
Less fuss with Tornado:Tornado DWG Scanner's Full text dump check lists every text string with its layer for every drawing in a folder, in one spreadsheet. Set Contains to a word or wildcard and only the matches come back. No script to write.
