Hi Todd!

I believe I answered your question on Discord already. I’ll paste the response from over there right here.

Have a look at this part of our documentation for how to detect planes: [https://lightship.dev/docs/ardk/ar\_world\_tracking/plane\_detection.html](https://lightship.dev/docs/ardk/ar_world_tracking/plane_detection.html)

You can see that when Anchors are being added, they are being referenced as an IARPlaneAnchor which has the following fields: [https://lightship.dev/docs/ardk/api-documentation/interface\_Niantic\_ARDK\_AR\_Anchors\_IARPlaneAnchor.html#index-0](https://lightship.dev/docs/ardk/api-documentation/interface_Niantic_ARDK_AR_Anchors_IARPlaneAnchor.html#index-0)

A plane anchor contains a Vector3 center and Vector3 extent which an estimation of how long and wide it is. Using these two you can either place content without the need of a user’s touch right in the center of the plane or using the approximations in the extent, place an object somewhere random
