Prices are US list prices checked 18 October 2026, before tax; regional prices can differ. Annual subscriptions are billed yearly. Add-ons and future upgrades can cost extra. Macadam is free during alpha; later pricing is not set.
Free options: Fusion Personal is restricted to qualifying non-commercial use; Shapr3D Basic allows two projects and limited exports; Onshape Free requires public, non-commercial documents. Plasticity offers a 30-day trial. Onshape CAM and Render Studio need Professional or above; CAM Studio Advanced is a separate offering.
Macadam native Windows, Linux and iPad apps, plus support for iPhone Duo, are coming soon. The web version already runs on iPhone; its touch workflow is still being improved. Mobile viewers are labelled separately from modelling apps. Onshape desktop access is through a browser; its mobile apps are native. Onshape provides 3D curve features rather than a general free-space 3D sketch editor; FeatureScript is code-based.
¹ Fusion browser access is streamed and requires a commercial or verified education entitlement; it is distinct from its browser-based file viewer.
² Rhino's developable-surface unrolling is useful for fabrication, but is distinct from a dedicated sheet-metal bend/flat-pattern workflow.
³ Macadam migration uses its Fusion export bundle and supported feature types; imported STEP files do not preserve a modelling timeline.
⁴ Hosted viewing is supported, but is not a downloadable self-contained viewer package. Macadam's package is read-only.
Macadam is alpha software. Availability does not imply the same geometry coverage, maturity or reliability across products. Macadam's GraphHopper editor remains a preview.
Paid plans may be needed. Extensions and plug-ins can add cost and may be platform-specific. A dash means not documented as an included capability. Last checked 18 October 2026.

A few things
to know.
Is Macadam free?
Macadam is free with full features during alpha. Future free and paid plans are still being defined; pricing and availability may change after alpha.
Where can I use it?
Try the web version now, on desktop or iPhone. The mobile web experience is still being improved. Native macOS, Windows and Linux versions are coming soon, along with apps for iPad and iPhone Duo. The Mac app is currently available in alpha.
Can I bring a model from Fusion?
Yes. The Macadam Fusion exporter creates a package Macadam can import. Supported features and known limitations are documented in the feature catalogue. The Stratocaster at the top of this page is imported with its Fusion feature history, then rendered and exported with Macadam.
Is the alpha ready for every project?
It is active software in development, with known limitations and bugs. Keep backups of important work and check geometry and machining output before using it.
