No Rhino, no plugins, no install. Free forever for the whole toolset — pay only when you need exact geometry, more sharing, or the formats that go into other tools.
Nothing is deleted and nothing locks. Every project you already have keeps opening, saving and exporting. You just cannot create new ones past the free limit until you delete something or resubscribe.
No. It is free permanently, with the full drawing and parametric toolset, the graph editor, and the engine running in your browser. The limits are on volume and on the formats other software needs, not on what you can build.
Any time, from your account page. You keep Pro until the end of the period you already paid for — we do not cut you off the day you click cancel. In the EU and UK you also have 14 days to change your mind entirely and get your money back.
Its headline feature — protected shares, where the definition never reaches the viewer — is not built yet. We would rather show you where this is going than sell you something that does not exist.
