Follow the cut through the building

A section is a cut through a building, taken at the line shown on another view. Open Banksia S two zero one when you are ready to study the drawings. Find the A to A cutting line, then open the A to A section, C one A three zero one. Check both identities and revisions. The written overall dimension is sixteen thousand millimetres. The section labels finished floor at ninety-nine point four zero and ridge at one hundred and four point two zero, on a fictional local datum. The difference is four point eight metres. Pause and make that comparison yourself. Then read the limitations. The section does not provide a connection design. The footing teaching image uses the same discipline: references lead you to schedules and other drawings. If those sources are absent, explain what remains unknown. A convincing picture is not a complete specification.
