An image-based schematic can show traced strokes, unresolved crossings, and nearby text. A crossing does not prove a junction, and nearby text does not prove a connection to equipment. These traces add no physical quantity or price. Open the source locations, then use manual takeoff if the drawing does not support a verified measurement. This lesson uses a labeled synthetic fixture and the real review controls; it does not demonstrate customer-plan accuracy.
- Expand the raster schematic traces.
- Open a traced stroke on its source page.
- Inspect the unresolved crossing.
- Inspect nearby text without treating it as a confirmed connection.
- Open manual takeoff for unresolved physical quantities.
