• namo.qty_runRuns a Quick or Zone Takeoff configuration and shows its result window: shared by the two takeoff buttons and Takeoff Templates.
• namo.qty_uiForms and windows of the Quantities panel (Quick Takeoff, Zone Takeoff, Takeoff Templates, COG Calculator), built on namo.ui.
• namo.reportsThe registry of automation-ready reports, and the helpers every report shares.
• namo.takeoffQuantity takeoff: measures from properties (and geometry), grouping, zones, workbooks.
• namo.uiWPF building blocks for Playground tools, themed from the pyNavis design system.
