3D Home Architect... $10 at Walmart.
Don't laugh! It does eveything I need it to do: Print out electrical plans to submit with proposals along with materials lists to spell out
exactly what I'm bidding for...
My shanty:
Floor plans, electrical plans, etc...
And 3D View too!
(Old hat and repeat material for some...)
There's a new version available for $50 that does more... Maybe even shows luminaires and devices in 3D View!
This is good for residential only, and cannot convert to CAD format for file sharing.
