The units in TestFit need to have an underlay image. ![unit plan in testfit](https://support.testfit.io/hs-fs/hubfs/CS%20-%20Customer%20Success/CS%20-%20Knowledge%20Base/CS%20-%20Knowledge%20Base/Features/unit%20plan%20in%20testfit.png?width=688&height=751&name=unit%20plan%20in%20testfit.png) 2. The model group ***does not*** include the exterior walls of the unit. ![interior walls](https://support.testfit.io/hs-fs/hubfs/CS%20-%20Customer%20Success/CS%20-%20Knowledge%20Base/CS%20-%20Knowledge%20Base/Features/interior%20walls.png?width=450&height=524&name=interior%20walls.png) 3. In Revit, the name of the model group needs to match the name of the unit in TestFit. ![group name](https://support.testfit.io/hs-fs/hubfs/CS%20-%20Customer%20Success/CS%20-%20Knowledge%20Base/CS%20-%20Knowledge%20Base/Features/group%20name.png?width=450&height=244&name=group%20name.png) 4. The anchor point of the model group is at the intersection of the walls in the bottom left corner of the unit. ![model group anchor](https://support.testfit.io/hs-fs/hubfs/CS%20-%20Customer%20Success/CS%20-%20Knowledge%20Base/CS%20-%20Knowledge%20Base/Features/model%20group%20anchor.png?width=688&height=330&name=model%20group%20anchor.png) --- ### TestFit In TestFit, you'll need to insert an image as an underlay. ![unlderlay image](https://support.testfit.io/hs-fs/hubfs/CS%20-%20Customer%20Success/CS%20-%20Knowledge%20Base/CS%20-%20Knowledge%20Base/Features/unlderlay%20image.gif?width=688&height=389&name=unlderlay%20image.gif) --- ### Revit 1.
