Measurement and purchase guides
- Apply banding cut allowance to every selected edge
- A reproducible two-stock cut plan can still cost more than another plan
- Keep first-emitter offset in a specified dripline takeoff
- Purchased stock length is not installed finished length
- Do not pool ridge lengths without checking cap cuts and overlaps
- Count visible coffer surfaces without doubling horizontal area
