Playbook (Interiors: Kitchens & Baths)
Audience: Interior designers moving day-to-day kitchen/bath workflows from SketchUp/LayOut to GstarBIM.
Outcome: Deliver faster, more reliable interior packages (plans, elevations with tiling and dimensions, room books, take‑offs) using GstarBIM’s native tools.
0) Success criteria (define before you start)
- 1 kitchen + 2 bathrooms documented to office standards in ≤ 2 iterations.
- Interior elevations auto-dimensioned; tiled surfaces patterned with counts.
- Schedules generated natively (rooms, tiling, cabinets, fittings) → Excel.
- One IFC exchange to architect/GC with no rework.
1) Pre‑flight inventory (from your SketchUp stack)
Gather the following so you can map them 1:1 into GstarBIM:
- SKP content: components for cabinets, appliances, sanitary, lighting; material swatches.
- LayOut assets: title blocks, page templates, scrapbooks (symbols, tags, notes).
- Extensions (note what they did): e.g., cabinet generators, reporting tools, pattern/tiling helpers, parametrics.
- Layer/Tag conventions: names, colors, lineweights. - Scenes: standard interior elevations, axons, 2D plans.
- Reports: CSV columns you rely on for quantities.
Create a 2‑column spreadsheet: “What we did in SketchUp” → “Target in GstarBIM”. Use the mapping table in 10. Migration cheat‑sheet ...
2) GstarBIM environment setup
- Project template (.TPL)
- Units, precision, project north.
- Stories/levels (e.g., Finished Floor, Ceiling Height presets).
- Dimension styles, text styles, arrowheads, hatch patterns.
- Default Layer Manager: walls/doors/windows, furniture, sanitary, lighting, annotations, tiling, construction.
- Libraries
- Cabinet templates (base, tall, wall; common widths/hinges/handles). Save as styles.
- Material & finish catalogs: tiles (size, pattern sets, grout), paints, veneers, worktops.
- Fixture content: import RFA/RVT or SKP for appliances/sanitary; standardize naming.
- Rooms/Zones
- Room categories (Kitchen, Bath, WC, Laundry) with finish schemas (wall/slab default finishes).
- Tiling styles
- Pattern presets (herringbone, 1/2, 1/3, hex, chevron), joint widths, starting points; waste factors.
- Title blocks & sheet sets
- Import/trace your LayOut title blocks; set fields (project, sheet no., revision, scale, drawn by). Save as templates.
3) Modeling workflow (kitchen)
- Shell & rooms
- Model walls/doors/windows as BIM elements; place Room objects for each interior space.
- Cabinetry
- Use Cabinet Editor: pick corpus, fronts, panels, plinths, worktops, hardware.
- Save common units as styles (B600 drawer stack, W900 corner, Tall600 oven tower, etc.).
- Place appliances as objects; align with cabinet fronts.
- Finishes
- Assign materials to fronts, carcasses, worktops. Parameterize thickness and overhangs.
- Lighting & power
- Place ceiling/wall lights and sockets as objects; ensure plan symbols map to schedules.
Deliverables
- Plan with automatic room/internal dimensions, furniture, and MEP symbols.
- Interior elevations (see §6) per wall run (A/B/C/D) with cabinet tags.
- Schedules: cabinet list, appliance list, lighting count, room finish schedule.
4) Modeling workflow (bathroom)
- Base modeling: walls/door, shower niche/bench as wall modifiers or objects.
- Sanitaryware: WC, basin, bath, mixers; keep naming consistent for schedules.
- Tiling
- Use Tiling on wall/slab faces: choose pattern, direction, start point, borders.
- Define accent walls/bands; per-surface offsets around openings.
- Apply different patterns per wall; mirror patterns when required.
- Accessories: mirrors, towel rails, cabinets as objects/cabinets.
Deliverables
- Interior elevations with tile patterns visible and dimensions to fittings.
- Tiling take‑off with counts/areas per room and per wall face.
5) Views, elevations & annotation
- Interior Elevation tool: generate elevations for a room with one command; name views (K-01‑A … K‑01‑D).
- Automatic dimensions
- Wall chains (overall + openings), internal room dims, cabinet widths, worktop heights.
- Tags/labels
- Room tags (area & finish key), cabinet tags (type/width), fixture tags, tile keys.
- Graphics
- View templates (lineweights, hatches, shadows); keep a clean monochrome doc style.
6) Sheets & revision management
- Place model views (plans, elevations, sections) on sheets; lock scale.
- Add schedules on the same sheets (live-linked): cabinet list, room finishes, tiling.
- Title block fields auto‑populate from project data.
- Revisions: duplicate sheet set per issue (A, B, C); bump revision/date in title block fields.
7) Quantities & schedules (out of the box)
- Rooms: name, area, perimeter, ceiling height, finish key.
- Cabinets: code, type, width, height, depth, finish, handle.
- Appliances/Sanitary: type, model, count, supplier.
- Tiling: tile code, size, area, pieces, waste %, grout color.
- Lighting: type, lumen class, count, circuit.
Tip: Create schedule styles with fixed column order and filters (e.g., by room category). Export to Excel for pricing.
8) Collaboration & exchange
- IFC to architects/General Contractors (walls/doors/windows/rooms).
- SKP/OBJ/FBX for visualization or vendor collaboration.
- RFA/RVT import to leverage manufacturer content; convert to native where helpful.
9) QA, standards, and model hygiene
- Naming: SpaceCode-RoomName (e.g., K‑01 Kitchen), CAB-B600-3DR, TILE-Hex-100.
- Layers: prefix by category (ANNO-, FURN-, SAN-, TILE-).
- Color by layer for quick visual audits.
- Pre‑issue checklist:
All rooms placed & named; elevations generated & titled. - Dimensions regenerate without warnings; no duplicate tags.
- Schedules populated; row counts match expected inventory.
- Sheet list complete; title blocks filled; revision/date correct.
10) Migration cheat‑sheet (SketchUp → GstarBIM)
| SketchUp concept | GstarBIM equivalent |
|---|---|
| Components / Groups | Objects / BIM elements / Cabinet assemblies |
| Dynamic Components | Parametric object styles / Cabinet parameters |
| Tags (Layers) | Layer Manager categories |
| Materials (textures) | Materials & Finish catalogs (with physical props) |
| Scenes (elevations, plans) | Saved Views (plans/sections/elevations/IE sets) |
| LayOut Sheets | Sheets with linked model views & live schedules |
| Scrapbooks (symbols) | Annotation libraries (tags, labels, symbols) |
| Generate Report | Built‑in Schedules (rooms, objects, tiling, cabinets) |
| Tiling via textures/extensions | Tiling tool with patterns/joints/waste |
| Cabinet extensions | Cabinet Editor + saved cabinet styles |
11) Pilot project recipe (2–3 days of focused work)
- Build your TPL: levels, layers, styles, title block (§2).
- Import 10–20 must‑have objects (appliances, sanitary, lights) as RFA/RVT/SKP.
- Create 5 cabinet styles (B300, B600 drawers, W900 corner, Tall600 oven, Tall600 pantry).
- Create 5 tiling presets (subway 1/2, 1/3, herringbone, hex, chevron) with standard joints.
- Model one kitchen + two baths.
- Generate room interior elevations and auto dimensions.
- Place schedules (rooms, cabinets, tiling, fixtures) on sheets.
- Export Excel and a coordinated IFC.
- Issue PDF set to your office standard.
- Retrospective: note bottlenecks and update the TPL/styles.
12) Common pitfalls & fixes
- Free‑form modeling instead of BIM elements → Use walls/doors/windows/rooms; keep objects for furniture/fixtures only.
- Forgetting Room objects → You’ll miss room tags and finish schedules; place Rooms early.
- Uncontrolled layers → Enforce layer prefixes; lock annotation on separate layers.
- Manual tile textures → Use the Tiling tool so counts & schedules update.
- Schedules off‑sheet → Place all key schedules on drawing sheets so clients see live data.
13) Starter assets you can standardize
- Title blocks (A1/A3 portrait/landscape, metric scales).
- Arrowheads, dimension/text styles (ISO‑like).
- Cabinet library (10–15 base units; 5 tall; 5 wall).
- Tiling presets (5–8 patterns) with standard grout colors.
- Annotation: room tags, cabinet tags, fixture tags, tile legends.
14) Optional: Cross‑software handoffs
- Send IFC to architects; receive structural shells back.
- Give subcontractors Excel take‑offs; attach PDFs of elevations with tile keys.
- Export SKP or FBX for visualization partners.
Next steps
- Duplicate this playbook per project and update your TPL as you refine standards.
- If you share your current LayOut templates and top extensions, we can tailor the layer naming, cabinet codes, and schedule columns to match your office language exactly.
