If you have invisible items in an IRRICAD Link design:-
Download the zip file from http://www.irricad.com/Irricad/Download ... howLSP.zip and save the file to your hard-drive. Double-click on the zip file and then copy the Show.lsp into your Irricad Link folder.
In IRRICAD Link APPLOAD the Show.lsp and action the SHOWENTS command. This will make the hidden items visible and you can then delete them.
