ARCHLine.XP vs. SketchUp

Quick verdict

SketchUp is a superb, general-purpose 3D modeler with a huge ecosystem. 
GstarBIM is a full BIM authoring platform built for architecture/interiors that produces coordinated drawings, schedules and IFC exchanges out of the box. 
If your deliverables include BIM data (IFC), coordinated documentation, and quantities without bolt-on workflows, GstarBIM is the better fit.

What each tool is built to do

• SketchUp: fast, flexible surface/mesh modeler (edges/faces → groups/components) with optional BIM data via classifiers and extensions; 2D sheets are produced in LayOut; Studio bundles V-Ray.
• GstarBIM: discipline-aware BIM authoring (walls, slabs, doors, windows, stairs, etc.) with coordinated 2D/3D views, live schedules/quantities, plot layouts and IFC exchange.

BIM depth & data fidelity

• GstarBIM: buildingSMART-certified IFC exchange (IFC2x3 CV2.0 import/export), with options to retain original geometry or convert to native elements on import. Recent materials note IFC 4.x support across versions.
• SketchUp: provides IFC import/export and has recently improved IFC attribute mapping and performance (2025), but Trimble’s public materials emphasize improvements rather than certification. (As of Aug 28, 2025 we did not find SketchUp listed among buildingSMART’s certified participants.)

Why it matters: certified IFC helps prevent data loss when collaborating with Revit/ArchiCAD/Allplan/Tekla and is often required on openBIM projects.

Documentation workflow (drawings, sheets, change propagation)

• GstarBIM: coordinated floor plans, sections/elevations, automatic dimensioning, tags and live schedules that update with the model; plot/print layouts link back to model views.
• SketchUp: relies on LayOut for 2D documentation; sheets update from the 3D model but many annotation conventions depend on LayOut setup and user discipline.

Quantities, schedules & take-offs

• GstarBIM: schedules are native, model-linked spreadsheets (rooms, doors, walls, finishes, etc.) and can export to Excel.
• SketchUp: quantities typically require extensions/workflows; not a native architectural schedule system. (SketchUp can classify components, but components remain edge/face geometry.)

Interoperability & content

• GstarBIM: broad I/O (DWG/DXF, SKP, OBJ/FBX, PDF), RFA/RVT import for leveraging Revit families, 3D Warehouse access, and certified IFC.
• SketchUp: extensive ecosystem (3D/Extension Warehouses), Studio adds Revit Importer; IFC improved in 2025.

Visualization

• SketchUp Studio includes V-Ray (Windows) for photorealistic rendering.
• GstarBIM includes an integrated rendering engine (recent releases highlight rendering upgrades)

Learning curve & UX

• SketchUp is famously quick to pick up for conceptual massing; geometry is free-form, organized into components/groups.
• GstarBIM provides an interface tailored to architecture/interior/furniture workflows (Design Center, BIM Property Grid; axonometric/2D+3D combined views), easing transition from pure modeling to BIM.

Why choose GstarBIM (the case in a nutshell)

1. Deliverables-ready BIM: native walls/doors/windows, rooms/zones, phases, coordinated drawings, and live schedules reduce reliance on add-ons and manual spreadsheets.
2. OpenBIM confidence: buildingSMART-certified IFC 2x3 CV2.0 import/export, plus IFC4.x support across versions.
3. Interoperability with Revit ecosystems: RFA/RVT import lets you reuse manufacturer content and partner libraries.
4. Faster documentation: automatic dimensioning, tags, plot layouts that stay linked to the model.
5. Quantities without distortions: built-in, model-driven take-offs to Excel (rooms, materials, objects).

When SketchUp still shines

• Early concept and visualization with minimal setup;
• Ecosystem depth (extensions for anything from parametrics to rendering);
• Studio bundle with V-Ray, Revit Importer, Scan Essentials (Windows). sketchup.trimble.comhelp.sketchup.comsee-it-3d-webstore.co.uk

Simple chooser

If your workflow or clients expect BIM-grade models, certified IFC exchange, coordinated drawings, and quantity schedules without depending on a patchwork of extensions, GstarBIM is purpose-built for that reality. 
If you’re primarily doing concept models, quick iterations, or visualization and are happy to assemble your toolchain (LayOut + extensions + V-Ray/others), SketchUp remains an excellent modeling hub. technical.buildingsmart.orgsketchup.trimble.com

Decision-focused comparison for interior designers
with the lens on day-to-day tasks (kitchens, bathrooms, finishes, elevations, quantities, client packs) and why GstarBIM is often the better fit.

What you do, and how each tool handles it

1) Kitchens, wardrobes & custom cabinetry

• GstarBIM: Purpose-built cabinet editor (corpus, panels, dividers, fronts) and full kitchen workflow using catalog items or custom furniture—geared to interiors, not just generic solids.
• SketchUp: You can model anything and pull assets from 3D Warehouse; cabinet systems typically rely on extensions or manual component setups. SketchUp’s interior page highlights assets/moodboards but not a native cabinet system. sketchup.trimble.com

Why choose GstarBIM: Faster from brief → cabinet set with fewer plugins and less manual parametrics.

2) Tiles, finishes & interior elevations

• GstarBIM: Dedicated Tiling tools (herringbone, hex, fishbone, metro shifts, etc.), place on expanded wall/slab surfaces, then keep counts/areas; interior elevations/sections stay linked to the model.
• SketchUp: Patterns achievable, but via manual drafting, textures, or extensions; interior elevations are created through scenes and documented in LayOut. help.sketchup.com+1

Why choose GstarBIM: You get a tiling workflow that understands rooms and surfaces, plus elevations that update with design changes—ideal for bathrooms and feature walls.

3) Quantities, room books & procurement

• GstarBIM: Live schedules (rooms, doors, finishes, tiles, cabinets, lighting, etc.) placed on sheets; update automatically when the model changes; export to spreadsheets. Training materials also call out tiling consignment lists.
• SketchUp: Has Generate Report (CSV) for component attributes, useful for take-offs, but you assemble reporting logic around components/classifications yourself. help.sketchup.com+1

Why choose GstarBIM: Out-of-the-box, interiors-centric schedules cut spreadsheet work and reduce human error.

4) Dimensioned sheets & client deliverables

• GstarBIM: Coordinated documentation (plans, sections, elevations), automatic wall dimensioning and room internal dimensions; sheets remain linked to model views.
• SketchUp: Uses LayOut for 2D documentation; updates come through when model changes, but standards rely on LayOut templates and user discipline. help.sketchup.com+1

Why choose GstarBIM: Less setup to get “interior package” drawings (plan + elevations with dims) consistently out the door.

5) BIM collaboration & content

• GstarBIM: buildingSMART-certified IFC 2x3 CV2.0 import/export; can import RFA/RVT content and convert many RVT elements to native ones. Direct SKP/3D Warehouse intake keeps your asset pipeline open. technical.buildingsmart.orgarchlinexp.com
• SketchUp: IFC workflows exist and have improved (IFC4 export/import updates), classification tools + Generate Report; Revit Importer is available in SketchUp Studio (Windows). help.sketchup.com+3help.sketchup.com+3help.sketchup.com+3

Why choose GstarBIM: For interior firms that must exchange data with architects/GCs via IFC—or borrow Revit families—GstarBIM offers certified IFC and direct RFA/RVT pipelines without stitching together multiple add-ons. technical.buildingsmart.org

Practical takeaways for interior designers

• Bathroom & kitchen speed: Tiling tools + cabinet editor + automatic dimensions = fewer hours from concept to priced set.
• Less “plugin hunting”: Schedules, elevations, room books, and tiling lists are native—no fragile combo of third-party extensions.
• Cleaner change management: Plans/elevations, dimensions, and schedules are live-linked, so revisions propagate reliably.
• Open ecosystem anyway: Still tap 3D Warehouse, SKP models, and Revit libraries when needed.

When SketchUp still makes sense

• Concept + visualization first: unmatched modeling fluency and an enormous extension/library ecosystem; LayOut is powerful once templated. Studio adds Revit Importer. sketchup.trimble.comhelp.sketchup.com+1

Simple chooser (interiors-centric)

If your deliverables routinely include kitchen/wardrobe packages, tiled bathroom elevations, room books, and procurement-ready schedules, GstarBIM minimizes manual setup and plugin dependencies while giving you certified IFC exchange and direct RFA/RVT/SKP intake. 
That translates into faster interior documentation and fewer errors—exactly where interior designers spend the most time.
