Hey BlenderNation & Fans,
This video seems to be popular and getting a positive response so if your interested in or are continually creating architectural scenes then the latest version of Archimesh has some great features and I packed ALL of them into this video. Check it out if you've never used Archimesh by Antonioya before or are considering installing it which is available from github.
