To link an AutoCAD file in Revit:
Go to the "Insert" tab.
Click "Link CAD."
Select the AutoCAD file (.dwg or .dxf).
Choose the desired options (e.g., scale, unit, layer).
Click "Open" to link the file.
The linked AutoCAD file will be displayed in Revit, allowing you to use it as a reference or for further development. Any changes to the original AutoCAD file will be reflected in Revit when reloading the link.
