Compare › twyk vs Onshape
Onshape is professional parametric CAD: you sketch with dimensions and constraints, build up a feature history, and design whole mechanical assemblies. It's powerful, with a learning curve to match, and on the free plan your documents are public and for non-commercial use. twyk is for getting printable parts made quickly: build it from editable shapes, size it to the millimetre, and check it prints. Your models stay private.
| twyk | Onshape | |
|---|---|---|
| Best used for | Getting from “I need this” to a part that prints: build it from shapes, size it to the millimetre, check it prints | Precise mechanical parts and assemblies |
| How you build | Drag & drop shapes and holes; then Sculpt, Formula and Bend | Parametric: sketches with measurements and constraints, plus a feature history |
| Learning curve | Low | High |
| Cost | Free: no plans, payments or subscriptions | Free for hobbyists (non-commercial); paid plans for professional use |
| Privacy on the free plan | Your models are private until you share them | Documents are public |
| Parametric history and constraints | Shapes keep editable settings, but there is no constraint-driven feature history | Yes, full parametric history and constraints |
| Assemblies | Groups of named parts; no mates or motion | Full assemblies with mates |
| Print checks | Flex test (PLA, PETG, TPU), Gaps clearance check, Lay flat, Cut big models in two | General CAD analysis, not print-specific |
| Export | STL, 3MF (named, coloured parts) | STEP, STL and many CAD formats |
Compiled in October 2026 from Onshape’s own website and help pages, and twyk’s help guide (sources below). “Not built in” means we couldn’t find it as a standard feature. Onshape is made by PTC; twyk is not affiliated with it. Spot something out of date? Tell us.
Export a part from Onshape as STL and import it into twyk, for example to personalise it or add a mount. Onshape remains the better home for the parametric source. See importing and exporting, or how to bring in models from any site.
For many 3D printing projects, yes: twyk is easier, free and private, with print checks built in. For mechanical assemblies that need constraints and full parametric history, Onshape is the better tool.
Yes. Documents created on Onshape's free plan are publicly accessible, and the plan is for non-commercial use. twyk models are private until you choose to share them.
Partly. Every twyk shape keeps its own settings, such as size, radius or number of teeth, which you can change later. twyk doesn't have sketch constraints or a feature history.
