AV Routing Mapper

Cases: add one from the toolbar, then set its name, size in U, and whether U1 is at the bottom (rack standard) or the top. Drag a case by its title bar to move it; you can have as many as you need.
Gear: drag from the left palette into a case, or click to drop it into the first free slot. Each item has a U height you can change, and moving it snaps to whole rack units. Occupied slots are refused, and the drop marker turns red when it won't fit.
Moving between cases: drag a unit across to another case, or pick a different case from its properties panel.
Front / Rear: Front view is your elevation drawing. Flip to Rear view to see each unit's connectors and drag between them to patch the rack internally — the cable types and colours are shared with the routing page.
Capacity: each case header shows used and free U, and "Pack gear to the top" closes up any gaps.
From Routing Page: click an item in that sidebar list to drop it into a case with its ports already set up, instead of entering it twice.
Export: rack elevation PDF (drawn to scale, with the patch list), rack build list CSV, and rear patch list CSV.
