Here’s a short summary of Home Design, Floorplan, Estimating softwares as well as some opinions:
Punch! (exclamation is part of the product name): website here is supposed to have a good floor plan builder with estimating built-in to the product. It has won numerous awards.
RS Means has an extensive collection of books on construction, including estimating software.
Broderbund 3D Home Architect: From personal experience: stay away from Broderbund Home Design. Rarely have I seen a product shipped with such poor quality. Check out the negative comments on Amazon.
Fast Plans: Link here I’ve never tried it, so let me know if you
Smart Draw: Link here. This is a free add-in module to Smart Draw for doing floorplans. It’s not bad.
Microsoft Visio: website diagram software has a floor-plan add in.
