Is it better to link or import CAD into Revit?

What is the difference between import CAD and Link CAD in Revit?

What is the difference between “link CAD files” and “import CAD files” in Revit? Linked files retain the reference to the external files and will update when the Revit model is reopened or the linked file is reloaded. Imported files become a part of the Revit model and lose any connection to the source.

Link a CAD file to a Revit model when you want to maintain a connection between the file and the model, so you can use the file as an underlay or include it in the construction documentation set. Open the Revit model. If you want the linked file to display only in a particular view, open that view.

How do you tell if a CAD file is linked or imported in Revit?

To confirm that the file was linked and not imported, click Manage tab Manage Projects panel Manage Links. In the Manage Links dialog, the CAD Formats tab lists all linked files. It does not list files that are imported. Therefore, if the file is not listed here, then it was imported.
