Attaching External Files
Using the referenceAttachment node in OpenBuildingsā¢ GenerativeComponents is the most integrated way to import an external geometry file into your model. This node is restricted to attaching MicroStation design files (*.DGN) only. After creating a new model attachment, the new node is recorded in the transaction file and can be played and edited like all other OpenBuildingsā¢ GenerativeComponents nodes.
When the original attached model is changed or edited in MicroStation, replaying the transaction updates the file to its current state.
