Lay the phone FLAT on the roof plane you’re reading — any direction. Hold still.
Nominal G-rib covers 36" (3′). Measure center-rib to center-rib across your first panels — it works out the real coverage for THIS job so the cuts come out exact. The permanent panel size lives in Settings.
Leave Bottom empty if there’s no bottom edge.
Tape it and check the grey number — a match means the valley’s square. Leave it blank to build as measured.
The rise you read straight off the valley for one 15⅝ run.
The straight measurement up the valley line. Must be longer than Length.
| # | Length | Rise/pc | Machine |

Full pieces fill the straight bottom run (green line), then the cut table steps down into the valley. Length steps on the total panel width; Short pt is the other end of the same diagonal cut. Machine = length + net adjustment (notch − machine offset), in machine tenths. Change machine numbers under the gear ⚙.
From the under-rib reference of the last piece before the apex, over to the apex. Pre-filled with the calculated number — edit it to what you actually measure and everything from the apex on updates.
Measure the diagonal off the previous piece; get the flat run and the rise where the cut starts.
