Hi Paul;
I work in AutoCAD 2010 so have a lot of model plans drawn in that format. Any of these plans can be exported as a dxf file which usually can be read and edited by most, if not all of the cad programs. If you have AutoCAD just tell me what version so I can send you a file in a version your program can read (anything prior to 2010 can not read the fie while anything later than 2010 can read the 2010 file). If you are working in something like Corel Draw I have a program that can convert my AutoCAD files into pdf files so that would also work for you.
Drop me an e mail to clflyer1943@gmail.com or call me at 951-409-1277 (Pacific Time Zone) if I can help.
Eric
