A plan-library approach for firms that want generated layouts to start from their own repeatable design knowledge.
Available · vendor documentedDocumentation review · not tested
Where it fits
Repeated housing layouts or unit families where a firm already knows what should be reused and what must remain editable.
What goes in
A Plan Library assembled from past projects, with the firm’s design rules and constraints.
What comes out
Generated layouts and BIM geometry; Finch lists Rhino, Revit and Grasshopper interoperability.
How to read the capability
Finch positions its library as the starting point for generation, with its Archie agent handling repetitive adjustments. The important procurement question is therefore how well your own standards can be encoded, updated and inspected—not merely how attractive a demonstration plan looks.
Limits to keep in view
Claims about code alignment and coordinated exports are vendor assertions, not GAD test results. An outdated library can reproduce outdated assumptions. Local approval, detailed coordination and exported object quality require independent review.
A practical evaluation checklist
01
Load one accepted and one deliberately unsuitable unit; see whether the library distinguishes their permitted uses.
02
Alter a door or corridor rule and inspect every affected linked unit for missed changes.
03
Open an exported model in your actual BIM template; inspect levels, categories, parameters and editability.
Read the output, not just the promise. These profiles summarize official documentation, not hands-on product reviews. Evaluation checklists are GAD editorial recommendations. Availability is scoped to the named feature; an experimental feature does not make the entire platform experimental. No paid placement determines this selection.
Finch: decide what a housing plan is allowed to change
English study · Chinese summary · · Study dated 2026-10-07
A reusable housing plan contains decisions about everyday life: where a resident enters, which rooms meet the facade and how a bathroom shares a service zone. Adapting that plan to a different outline should preserve the decisions that matter while exposing the ones that change. Finch's adaptive library makes this a concrete review problem. The useful question is what a plan may stretch, and what must remain fixed.
The official Adaptive Plan Library guide describes a stretch preview and wall constraints. A locked wall resists stretching; an extendable constraint permits stretching but prevents shrinking. These are useful controls for a repeatable unit, but an office must decide which architectural requirement each control represents. A minimum room dimension, a retained service position and a preferred proportion are different instructions, even when they appear together in one drawing.
Start a library review with one accepted unit and a short schedule of its reasons. Record the entry side, the rooms requiring external frontage, the service connections and the dimensions that cannot reduce. Give preferences their own status. If a generous dining area may shrink while a particular doorway must remain unchanged, that distinction should survive both the stored plan and the review conversation. Record the source project and the circumstances under which its approval was given.
Finch's assignment documentation distinguishes pasting a plan as it stands from adapting it with rotation and stretching constraints. It also describes an Adaptivity Score expressing compatibility with the receiving unit. Treat that score as a reason to inspect a candidate. It cannot tell the team whether the new elevation, structure or building services support the same residential arrangement.
A useful office exercise would compare three receiving outlines: a close match, a narrower version and a unit with a different entry relationship. Keep the original plan visible beside each result. Measure which room absorbed the change, whether the route through the dwelling became awkward and whether storage or furniture now occupies useful circulation space. Record any manual repair against the rule that failed to protect the design. These are proposed evaluation cases, not results from a GAD software test.
The unit-plan tutorial describes room-level fit information, facade-related daylight checks and linked mirrored units. That last capability deserves a separate review. Identical outlines do not necessarily share the same outlook, neighboring obstruction or service condition. After a linked edit, inspect a typical unit and every location whose external conditions differ. A facade-contact indicator should not be presented as a project daylight assessment.
The resulting library should function as maintained design knowledge. Keep a revision, a responsible reviewer and a record of permitted uses with each accepted plan. When a requirement changes, review the affected family before reusing it again. Finch can help a practice explore how known plans occupy new envelopes; the architectural value depends on making the limits of that reuse legible.
