I like how easy it is for anyone who knows nothing about computers or building codes etc.,to use this program without having all these experts around you! It's really great that there are people out here with no experience in construction/building code stuff but can still figure everything they need themselves using virtual property architect!! The only thing i don't think would be useful if more options were added as far as exterior lighting fixtures go (like some programs have). Other than anything else though its pretty good.
