Collaboration
Cadre lets you share a model and get suggestions back — without handing over your file. Collaboration is built around presence and asynchronous review, not a shared live document.
What it is (and is not)
Collaboration in Cadre is host-authoritative presence plus asynchronous suggestions. One person owns the model; others see it, fork a copy, and send suggestions that the owner accepts or discards.
It is not live, simultaneous, two-people-editing-one-model co-editing. Two people do not type into the same model at once. The pattern is “share a link, get suggestions back,” and the owner always stays in control of what lands.
Share a link
A saved model gets a stable share link. Open it and, if the owner is online, you see their presence — cursors and avatars — updating live as they work; if they are offline, you see the latest saved snapshot. One link, either way.
Fork, suggest, accept
- A viewer forks the model into their own local copy.
- They edit freely and submit a suggestion.
- The suggestion lands in the owner’s review inbox with a visual diff of what changed.
- The owner accepts or discards it.
For a parametric part, a suggestion is a typed parameter change that applies as a single, reversible history entry — the same path an AI suggestion takes.
Comments and checkpoints
- Pinned comments — double-click any surface to attach a comment anchored to that point in 3D. Comments sync to everyone viewing.
- Named checkpoints — save a snapshot of the model at a moment worth returning to, with a thumbnail.
Why this shape
Presence tells you who is looking; the suggestion inbox keeps every change reviewable and reversible; host-authority means your model is never edited out from under you. Human review and AI review share one pipeline, so feedback from a person and feedback from the reviewer are handled with the same care.
