I was writing last time about precision. Let’s be more precise!

I like working to scale, in meters, I want my doors, windows, story heights and main elements in exact size and all objects aligned with snapping methods, no “invisible” overlaps or gaps to generate lighting artifacts or selection headaches and I can do this with Blender using the following tools (this is my list so far, I keep discovering new stuff)

• grid snap
• object snap
• constraints
• manipulators
• keyboard numeric input
• show edge lenghts
• the transform properties toolbox
• cursor placing
• object center placing
• transform orientations
• align rotation with the snapping target
