DWG Cataloger is a small utility that will help you create HTML catalog of your DWG files, allows you to to extract thumbnail images from DWG's and generate an HTML page of those thumbnails with links to the DWG.
You can generate an HTML page to display the thumbnail previews in a grid from 1 to 5 columns. The links to the images and DWG files can use relative paths and so the HTML page can be easily transferred on CD-ROM. This can be a really useful way of creating an index for a backup set or electronic issue.
