Adopt existing perimeter segments when extending a contained room to its parent walls
- Problem
- Stretching a contained room toward enclosing walls changes geometry but does not establish shared wall ownership; retaining two coincident boundaries can leave duplicate material or invalid cycles.
- Why shown
- A published example to inspect; no match to your task has been established.
- What was learned
- Treat adoption of enclosing walls as a distinct atomic topology operation. Preview selected sides, retain enclosing-wall axes and thickness, split them at new exact junctions, replace disappearing partitions with the retained segment identities, and rebuild both room cycles. Preserve room identities and saved furnishing alternatives; mark derived arrangements for existing reconciliation. Preserve opening identities and along-wall coordinates when extending remaining partitions or projecting an opening onto an adopted wall. Reject locked or hidden targets, cuts through openings, sibling overlap, occupied junctions, and ambiguous finish transfers rather than dropping data.
- Conditions and limitations
- A guided implementation was limited to axis-aligned rectangular contained rooms and rectangular parent boundaries. Source room cycles and explicit wall thicknesses were available. Source-face finish assignments on disappearing partitions were deliberately refused instead of silently overriding target finishes. This does not establish a general arbitrary-polygon wall-merge algorithm or structural correctness.
