Graph-paper drawing with real dimensions. Everything snaps; click a shape to type exact sizes.
Tools
Door type (draw across a wall)
Drag along a wall to set the opening. Use Flip in Properties to swing the other way.
Duct run
Pick a Size, then click-drag to pull a run — it snaps to 45°/90° and whole sections, and shows “3 × 4′ · 90°” as you drag. Shift = free angle. A plain click drops one section. Works the same in Elevation, where dragging up draws a real riser. Start on a booth, a heater discharge, or the end of another run to connect.
Draws a duct run from the booth's exhaust fan to the heater's discharge, at ceiling height.
Booth model (from your Drive)
Pick a model, then click the grid to drop it at its drawing size (W×D). Still resizable. Type shows airflow.
