Claris Corp's CAD Technical drawing application, "ClarisCAD 2.0v3".
This archive contains the original installer set of ClarisCAD 2.0v3
(floppy disk image files).

There is also a non-install disk image as an alternative (Top DL):
? clariscad.sit

Below this are five 800k Disk Copy 4.2 files making up the installer
set for ClarisCAD 2.0v3:
? Claris_CAD_program 1.image.sit
? Claris_CAD_program 2.image.sit
? Claris_CAD_Help.image.sit
? CAD_2.0_Tutorial_Files.image.sit
? Claris_CAD_Utilities.image.sit

An extra filter that supplied by Claris is included that export EPS
files for other DTP applications:
? Claris_CAD_EPSF Filter.sit

Finally, two 800 Disk Copy 4.2 files making up the CGT installer set:
? CGT_Program.image.sit
? CGT_Utilities.image.sit

All the above disk images are 'clean' as in they have not been
registered with a name, you can fill in your details etc. A serial
number is not required either.

If you don't have a floppy drive on your mac, download the (Top DL) CD
image, it contains all the files above and is drag and drop into the
relevant folder locations - instructions are in the disk image.
Don't forget to change the memory allocation via get info on the
closed program.
I hope this has been of help to someone.

Compatibility
Architecture: 68k

Tested on Mac OS 7 but probably works in Mac OS 6

ClarisCad 2.0v3 will run in 9.2.2 provided that it runs from and files
are saved in a partition no greater than 2Gb and the program memory
requirements (via get info on a closed program) are set to more than
4Mb - 4096k. If not the message about needing 1byte will display. It
will also run quite happily in classic mode in OSX but double clicking
a Claris file will not open it, you must use File / Open.
