Just checked on 'tinternet and XCAD designer is on CU Amiga disk 96. Click here and goto coverdisk 96 and download. Don't know if it's the final version though. Also XCAD 2000 is on Amiga magazine disk 144.
Scratch that XCAD 2000 is on CU Amiga coverdisk 144 and can be DL'd from same link as XCAD designer.
