Sorry to bring this up again but I can't get it to work. I now have winrar opened the file, removed the txt file extention, loaded the lisp and i get the same error.
"Write analysis to a file? [Yes/No] : y Enter file name <>
CRASHES AGAIN SAVE THESE\3DMASS.mpr>: c:/acadmass
"C:\acadmass.mpr": Can't open file
Command: ; error: bad argument type: FILE nil"
I'm not sure if its me loading the code, my version of acad(2006), or loosing some thing in the transfer of the code. If you could email me the txt file that you used that might fix my problem. thankx a million.
