When creating a transform into an FDM type, it is necessary to provide the externalId of the instance. Does the value of externalId need to be unique across all instances of all types in the model or only across instances of the given type?

Best answer by Anders Hafreager

The externalId is the id of an instance (a node) which may have multiple types attached to it. A node can both be Equipment and Pump. In FDM, nodes exist in a space, and all externalId’s have to be unique within a space.
