You can run clash detections between two models as well as within a single model. You can also use the Autodesk BIM 360 Glue Clash PinPoint feature. Clash PinPoint allows you to isolate clashing elements from BIM 360 Glue in both Revit and AutoCAD.
In View options, you can use Reveal Hidden Elements to view the objects in context.
For more information, see Running Clash Detections.
