When using a coordination model as a reference for your Revit model, you can manage the link to the coordination model as needed.
Unload a coordination model to temporarily remove it from the Revit model. For example, you may want to unload the coordination model when you finish an interference check, and you don't want it to be visible in views while you continue to work on the Revit model. Unloading the coordination model can also improve performance.
When you close and re-open the Revit model, the coordination model automatically reloads with updates, if any. To update it without closing the Revit model, use Reload or Reload From.
When reloaded, the coordination model retains its position and orientation in relation to the Revit model.
If the coordination model has been moved to a new folder or you want to reload it using a different edition of the file, click Reload From, and navigate to the target model. To avoid broken links in the future, change its Path Type from Absolute to Relative.
When you link a coordination model to the host Revit model, the dialog displays its absolute path.
Specify a relative path to avoid broken links if you later move the coordination model and its host model to a different location. For more information, see About Directory Paths for Linked Models.
For example, the models may reside in the same folder, or the coordination model may reside in a subfolder of the host model.
To delete the coordination model from the Revit model, use Remove. To restore the coordination model, insert it as a new link.
