Source. The controlling document starts the record.
The wood surface is an illustrative reference. Native geometry is an undimensioned illustration; quantities come from these records. Symbolic groups are not piece counts. A stated groove does not establish its dimensions.

Annotations are reviewer-created evidence links. They do not verify quantities, drawing scale or an extracted requirement. Select a highlighted region to return to its takeoff row.

REVISION REVIEW
A new revision.
A different material list.
Compare the requirements, then inspect what changed. Quantity changes stay separate from profile changes. Nothing is silently merged into your takeoff.
Illustration: two fictional schedules, with values stated for this exercise. Upload both revisions to compare your own lists. This compares stated records, not drawing geometry or automatic PDF extraction.
Watch the material record change.

Not present → Square edge
The change labels and values come from the record comparison below. Drawn groups are symbolic; a board does not represent one LF. Profile cuts are undimensioned schematics only when stated in the record.

Explicit
Written in a source. Check the document and revision.
Inferred
A reasoned interpretation. It is not a specification.
Suggested
A planning recommendation, kept separate from requirements.
