# Yet another simple 3D mechanical object. This one whas taken from
# PC MAGAZINE volume 8 number 2, January 31, 1989, page 34. This was example
# that was implemented under AutoCAD ver 10, and it looked nice so I tried
# it... It took me about an hour to complete.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
