uMake vs SketchUp: which 3D app is right for you?
Updated October 5, 2026
The short answerPick uMake if you want to sketch and shape curved forms in 3D with Apple Pencil, use AI that builds editable models, and keep a project on one board on iPad, iPhone or Mac. Pick SketchUp if you model buildings and interiors in an established desktop workflow, need construction documents, DWG or IFC files, or rely on its extensions and model library. uMake opens SketchUp files, so you can use both.
Two different kinds of 3D app
SketchUp, from Trimble, is a 3D modeler for architecture, construction, interior design, landscape architecture and urban planning. It runs on Windows and Mac desktops, in a web browser and on iPad. Around it sit LayOut for 2D design documentation, the Extension Warehouse of add-ons, and 3D Warehouse, a large library of ready-made models and materials.
uMake is a 3D design app for sketching and shaping ideas. You draw curves with Apple Pencil, a finger or a trackpad, lift them into NURBS surfaces and solids to real dimensions, and present the result with renders, scenes and AR. It runs on iPad, iPhone (including iPhone Duo with iOS 27.1) and Mac with Apple silicon.
At a glance
| uMake | SketchUp | |
|---|---|---|
| Platforms | iPad, iPhone (including iPhone Duo) and Mac with Apple silicon | Windows and Mac desktops, web browser and iPad |
| Best at | Sketching and shaping forms in 3D, especially curved ones; concept design and presentation | Buildings, interiors and sites, with an established professional workflow |
| Modeling approach | Curves lifted into NURBS surfaces and solids; Extrude, Revolve, Loft, Combine, Project Shape | Drawn edges and faces turned into 3D with tools such as Push/Pull |
| Documentation | Not for construction drawings; no DWG or DXF | LayOut for 2D design documentation; DWG and DXF import and export |
| AI tools | AI Design Partner builds and edits editable 3D geometry, including floor plans from a plan image; Live AI Preview renders as you model | AI Render turns the viewport into a rendered image; AI Assistant answers questions and generates objects |
| Boards/ideation | Spaces: an infinite board for sketches, notes, photos and live 3D designs | No equivalent listed on SketchUp’s site |
| Extensions and content | A built-in content library of models and materials | Extension Warehouse and 3D Warehouse |
| File exchange | Imports SketchUp (SKP), STEP, IGES, OBJ, STL, USDZ, GLB, DAE, SVG; exports STEP, IGES, OBJ, STL, USDZ | Native SKP; DWG, DXF, IFC, OBJ, STL, DAE, FBX, USDZ, glTF and more, depending on the subscription |
| Getting started free | Free to download; opening and viewing 3D files, including SketchUp, is free; drawing, editing and export need a plan | SketchUp Free runs in a web browser |
When to choose uMake
- You think by sketching. Freestyle strokes with ink, pencil, marker, charcoal and chalk brushes land in 3D space, Pen lays down smooth curves, and Precision chains exact lines and arcs. On iPad, Apple Pencil Mode lets the Pencil draw while a finger orbits the view.
- Your forms are curved. NURBS surfaces you reshape by their control points, Loft and Revolve, and Project Shape to wrap a pattern onto a curved body suit furniture, products and sculptural architecture.
- You want AI that builds geometry. AI Design Partner builds and edits editable 3D geometry from words or a reference image, and builds a floor plan from a plan image, up to three stories with stairs. Live AI Preview renders your model beside it as you work (AI in uMake).
- You want the project on one board. Spaces holds sketches, notes, photos, videos and live 3D designs, with layers, an underlay for tracing plans, and AI image tools such as Variations and Compose a Scene (Spaces).
- You work away from a desk. The same designs on iPad, iPhone and Mac, offline, with View in AR on iPhone and iPad to check a design at real size in the room.
- You need CAD exchange. With a plan, uMake exports STEP and IGES for other CAD tools (uMake vs Shapr3D).
When to choose SketchUp
- Your office already works in SketchUp. Shared files, templates and habits are worth a lot, and switching tools has a real cost.
- You need construction documents. LayOut turns models into 2D documentation, and SketchUp imports and exports DWG and DXF. uMake doesn’t read or write DWG or DXF.
- You work with BIM. SketchUp imports and exports IFC. uMake doesn’t.
- You rely on extensions and ready-made models. The Extension Warehouse and 3D Warehouse are a big part of many SketchUp workflows.
- You need Windows or a browser. uMake runs on iPad, iPhone and Mac with Apple silicon only.
For an architecture or interiors practice that documents projects as drawings and exchanges DWG or IFC files with consultants, SketchUp is the better choice.
Using both together
uMake opens SketchUp (SKP) files for free; they’re converted online, so the import needs a connection. That makes it easy to bring a SketchUp model into uMake to sketch over it, render it with Live AI Preview, stage it in Scene Studio or pin it in a Space next to references.
Going the other way, export a form you’ve shaped in uMake as OBJ, STL or USDZ, which SketchUp imports, and place it in the building model. uMake doesn’t export SKP.
OBJ, STL and USDZ arrive in SketchUp as meshes, so keep the uMake file as the master for curved pieces and re-export when the form changes.
Can uMake open SketchUp files?
Yes, for free, on iPad, iPhone and Mac. SketchUp files are converted online, so the import needs a connection. uMake doesn’t export SKP.
Is uMake a SketchUp alternative for architects?
For early design, massing, sketching over plans and presenting ideas, it can be. For construction documents, DWG and IFC exchange, and extension-based workflows, SketchUp is the better tool.
Which is better on iPad?
Both run on iPad. uMake is built around drawing in 3D with Apple Pencil or a finger, with AI and a project board alongside. SketchUp for iPad brings SketchUp’s modeling, including Push/Pull, and its own file format to the tablet.
Do both have AI?
Yes. SketchUp’s AI Render makes images from your model and its AI Assistant can generate objects. uMake’s AI Design Partner builds and edits editable 3D geometry on your canvas, and Live AI Preview renders the model as you work.
Can I get a uMake model into SketchUp?
Yes. With a plan, export OBJ, STL or USDZ from uMake and import it into SketchUp.
Try it in uMake.
uMake is free to download for iPad, iPhone and Mac.
