Have an agent find or make an object

You willAsk the connector for an item to a requirement and get one that fits, never a near miss passed off as a match.

Time3 min

Why it mattersAn agent can search, compare and build a custom item in one go, and tells you what it changed.

You needA connected agent.

Try it in Plotlay → Opens Plotlay with this lesson beside it. Nothing to install.

Steps

Give the requirement and the hard numbers: “a bathroom vanity 1800 ±10 wide, 460 deep, 850 high, 2 drawers and a 600 open shelf”.
The agent uses find_or_create_object. 1 Search: the Library and your objects. 2 Compare: each item is built and measured (size, drawers, doors, the open section, how it mounts, its finish). 3 Use it if exact. 4 Otherwise adjust a copy of the closest one whose own settings can meet it. 5 Otherwise build it from parts.
It reports close items with what differs (“width 900 vs 1800; no open shelf”) and what it made, measured again. Anything still missing a constraint is said plainly and not placed unless you agree.
What it makes is saved to your library (or the project) and placed with add_item. Open it in the app under My objects to adjust it by hand in the builder.

The same works by hand: Find or make in the Library tab.
An agent can also build an object from a parts list in one call (create_object), copy and adjust a Library item (copy_library_item), import a model file and change versions everywhere or for new placements only.

Leaving out the numbers that matter: without them any vanity is “a vanity”. Give sizes with a tolerance.

Check yourself

Nothing in the Library meets the size and drawers you asked for. What does the agent do with create on?

Places the closest vanity Copies and adjusts the closest adjustable item, else builds one, and says if anything still misses Gives up

Joinery (bench run): Built-in cabinetry along a wall, such as a kitchen or laundry bench with base cupboards, drawers and handles. Plotlay draws it on plans, elevations and in 3D.
Library: Real-sized things to place, by category and subcategory: kitchen, bathroom, furniture, lighting, power, heating, stairs, outdoor, site, commercial, vehicles, plants. Search in your own words (GPO, countertop), filter, and star favourites.
Elevation and section: An elevation is a side of the house, or a wall from inside, drawn straight on. A section is a cut through the building along a line you place.
Tolerance: How far a value may miss a rule’s limit and still show WARN rather than FAIL: a 6000 mm setback with a 200 mm tolerance accepts 5800 mm as WARN. A warn band does the reverse for a pass close to the limit.
