Apple Macintosh Claris CAD and Claris WORKS Files Converted to PDF

The staff is dedicated and easy to work with. My project was extremely challenging. Original files were created in the 80's using Apple Macintosh Claris CAD software that is no longer supported and existing copies had no Resource Forks. I had attempted for months to downgrade a MacIntosh Operating System so I could load Claris CAD software to open files and had no luck.

Howard was able to convert my files to functional PDF files and has made my project a huge success! I am eternally grateful!

Hello Barry,
Many thanks for choosing us to convert your Claris Cad files. The Mac files consist of 2 parts, a Data Fork and Resource Fork. Sometimes when the files are backed up on different systems like Windows, Unix etc, the Resource fork becomes separated lost.
The Resource Fork is a vital component for Classic Mac OS systems as it tells the Mac which application to use, along with some configuration options and icon for the file. Without it, the Mac Software cannot open the file.
So using a hex editor I manually rebuilt the Resource Fork for each file, then loaded them in to ClarisCad and Claris Works, finally printing them out into PDF, as well as converting to Microsft Word.
Microsoft Word allows easier editing of the file than PDF (PDF usually being a final printing format as opposed to a creation / editing format).
Thanks very much Barry for taking the time to review the work, and so glad you are enjoying editing the CAD files again.
Kind regards, Howard
