I have been tasked to design a network for my church and right now the only diagrams that exist is hand drawn so I'd like to computerize the layout. I'd like to do it not only for presentation of where I'd like to place network ports but eventually electrical & telephone lines. So I need something fairly simple to use for a person who has never used a cad program, but with reasonable accuracy. Also, free and/or cheap. I found Archimedes on SourceForge, but I don't know of its capabilities or how well it works. Can someone give any suggestions/opinions? TIA
