- 01
Draw Once.
Draw the plan, press 2D→3D. Walls miter, rooms close, slab and roof arrive. No push/pull, no holes cut by hand.
- 02
Change Anytime.
Move a wall with SketchUp's own Move tool. 150 ms later corners, openings, slab, roof and skirting rebuild — inside one Ctrl+Z.
- 03
Measure Automatically.
Walls, doors, windows, rooms, slab, roof, columns and curtains leave the model as a CSV take-off — concrete m³ included.

The technical bit

- Version

- Interface languages
- tr · en
- Reactive engine: an EntitiesObserver collects the dirty entity ids, waits out a 150 ms debounce, then rebuilds inside one transaction with observers suspended - so re-mitering, neighbour drag, opening re-cut, dimensions, room detection, slab, top plate, roof, skirting and furniture all fold into a single Ctrl+Z.
- Walls: corners mitered where they meet, alignment cycled centre / left face / right face with Tab, typed lengths, angle lock, curved (arc/bulge) walls, a sloped top stored as a wall property, and 25 / 20 / 13.5 / 10 cm thickness chips.
- Openings belong to the wall, not the model: a door or window is stored on its owning wall and re-cut whenever that wall moves, stretches or changes thickness. Two-click door placement sets hinge side and swing; the window head defaults to storey height minus a 60 cm beam. Quick Change swaps a placed opening for a catalogue model - one opening, or every opening in the model at once, with thumbnails.
- Analytic room detection from a planar graph: node welding on a spatial grid, T-point splitting, directed edge traversal, 15 cm open-corner tolerance, curved walls included as facet polylines.
- Slab per building from the closed outer wall outline with doorway gaps bridged, then a top plate with a 50 cm default projection for the roof eave to sit on. The roof engine covers five types - gable, hip, half-hip, shed, flat - with an analytic closed plate, ridge direction and slope, purlins and rafters under the covering, gutter, ridge cap, terrace parapet and roof-from-selection.
- Columns land exactly on SketchUp's own inferred point (endpoint, midpoint, intersection, edge, face - height included), rectangular or L section, Tab to rotate, Shift+Tab to cycle the held point, Ctrl for the wall magnet, plus a columns-at-every-corner command. Beams take their drop and width measured inwards from the outer face, miter against neighbouring beams at corners, drop the wall top beneath them and let it return when the beam is deleted.
- Five plugins compiled in, not required as installs: Dynamic Skirting 1.3.1 (skirting and cornice appear when a room closes, skip door gaps, follow wall edits), WindowFun Studio 2.5.0 (56 windows), Kapi Studyosu 1.6.0 (63 doors), PerdeNese Studio 2.2.1 (19 curtain systems) and StairFun Studio 1.0.12 (8 stair types, rebuilt in place when you change the type). Rule-based furnishing runs off data/rules.json plus your own .skp library, with a Rearrange re-seed and a collision re-check when walls move.
- Magic Wand: click any object and its own editor opens - wall properties, quick change, column, beam, roof, stair, curtain and skirting boxes - mirrored in the right-click menu, with a "What is this?" identifier alongside. The whole interface is driven from lang/*.json, and one TR|EN button relabels toolbar, panel, manual and the embedded studios in a single step; the in-extension manual ships in both languages with its own Markdown viewer.
- Output: a take-off of walls, doors, windows, rooms, slabs, roof, skirting, columns and curtains - column count and concrete m3 included - exportable as CSV; a solid plan section at 1.20 m and a two-click vertical section; and Export Component Copy (SKP), a duplicate of the model with every object converted to a named component for 3ds Max and other downstream tools, leaving the working model untouched.
- Built to be checkable: the pure-math cores (geom2, wall_math, opening_math, room_math, roof_math, stair_math, furnish_math, takeoff_math) run headless, so 1627 assertions across 31 test files pass without SketchUp open, and test_compat scans the source for Ruby 3-only syntax, non-ES5 JS and modern CSS so 2021-2023 keeps working. Nothing fails silently either: message box, Error Console panel, archiflow_log.txt and a single-file diagnostic report covering environment, settings, model summary, checks, errors and log.
Still being built
Shipped, and what is next.
Shipped
- v1.51-1.56: five studios embedded - skirting, curtains, doors, windows and stairs now live inside ArchiFlow, so no feature depends on a plugin you have to install separately
- v1.57.0: roof engine - gable, hip, half-hip, shed and flat, with an analytic closed plate, ridge direction and slope, purlins and rafters, gutter, ridge cap and roof-from-selection
- v1.59.0: full English interface - every string a user reads comes from lang/*.json, guarded by test_i18n so no Turkish leaks through
- v1.61.0: one labelled toolbar with the TR|EN switch and the user manual in the title bar, the native toolbar retired, and 1627 assertions green across 31 test files
- Export Component Copy (SKP): a duplicate of the model with every object converted to a named component for 3ds Max and other downstream tools, leaving the working model untouched
Next
- Plan Reader and the extension's own Ruby DXF reader out from behind Commands::DEV_FEATURES - open an existing plan, with its units, layers, text, arcs and blocks, and trace it straight into walls
- Key activation replacing the non-enforcing license stub, so the 16-hour trial becomes a real trial and a purchase becomes a real key
- The manual SketchUp pass the 1.55-1.61 features are waiting on, together with the open items: 3D railings on L, U and spiral stairs, skirting that wraps a free-standing column, and 10 cm wall thickness fixed
Before you ask
It installs as an .rbz into SketchUp 2021 through 2026. The Ruby is written to 2.7, the panel JavaScript to ES5 and the CSS to the old Chromium in 2021-2023, and test_compat scans the source on every build to keep it that way. Nothing else is needed: skirting, curtains, stairs and the door and window catalogues are five separate plugins compiled into this one, so a fresh machine gets the whole set from a single file. The honest caveat is that day-to-day development runs on 2024-2026 and 2021-2023 has not been hand-tested yet.
None of those today. The build ships with a license stub that enforces nothing: it counts a 16-hour usage trial and then keeps working, and there is no key server live yet, so the extension does not phone home and cannot expire in the middle of a project. The $45 is a suggested price, not a confirmed one. Key activation is on the roadmap; when it arrives it replaces the stub, not the way you model.
Three gaps worth knowing before you buy. First, the visual Plan Reader and the extension's own Ruby DXF reader are written but switched off behind the Commands::DEV_FEATURES flag until a later release, so today you draw the plan in SketchUp rather than importing one. Second, the open issues: 3D railings are generated only on straight stairs, skirting does not wrap a free-standing column standing inside a room, and one user plan produced thickness errors on 10 cm walls. Third, much of the 1.55-1.61 work - embedded skirting and curtains, quick change, the top plate, the new labelled toolbar - is written and green in the headless suite but still waiting on a manual pass inside SketchUp.

Why Use Plugins in SketchUp at All?
You do not need forty of them. But it helps to know what a .rbz really is, whether it is safe, what it costs you at startup, and the two jobs SketchUp will never do on its own.
