There are currently 3 commands for Crash.

Join a Multi-User model

Open up Rhino, Ensure you’re in an empty new model. You can save it, but this is not required*, and then run the **JoinSharedModel** Command

Release your changes

When you have finished working in your model and you want everyone else to have the changes you can release them by using the Release or the Release Selected command. This will force-bake the changes for everyone else automatically.

Close a Multi-User model

Use the **LeaveSharedModel** command and you can empty the model and choose to release all your final changes, or leave them as temporary.


Creating Geometry for a model

You can create geometry as usual and it will be sent to others in your model. Check out the ‣ & Known issues for unsupported features at this time.

Warnings and Errors

Crash is still WIP so you’re likely to see these from time to time.

I see red boxes and got a message about Changes not being sent!

Below shows an example project. The Red Boxes indicate geometry that could not be sent for one or more reasons. Other users will not see this geometry or the boxes. The most likely reason is that it is too big and complex! Crash can be configured for larger geometry, but for now this geometry will need to be broken up to be sent.
