Field notes
The homepage says measurements can be entered as feet and inches, decimals, or metric, with units following the browser unless changed. It describes copyable results for messages or materials orders and lists examples such as editable deck costs, roof bundles, and stair risers. These are presented as planning estimates, with a warning to verify relevant work against local building requirements.
