Hi @kabochow ,

Unfortunately, the level of feature recognition you are describing is not provided with the HOOPS Communicator SDK.

Regarding getting the surface area of a face with Communicator, it looks like @tino was able to to provide some guidance in [this post](https://forum.techsoft3d.com/t/is-there-a-way-to-get-the-surface-area-of-the-face/3838/4). I would just add that you may also be able to calculate it if you are using [HOOPS Exchange](https://docs.techsoft3d.com/exchange/latest/api/group __a3d__ physical__properties.html#_CPPv418A3DComputeFaceAreaPK11A3DTopoFacePK14A3DTopoContextP9A3DDouble) (which is part of [HOOPS Web Platform](https://www.techsoft3d.com/products/hoops/web-platform)). In this case, you’d be working with an additional API and need to [link your Communicator and Exchange data](https://forum.techsoft3d.com/t/how-to-one-to-one-correspondence-between-the-nodes-fetched-in-the-hoopsexchange-code-and-the-scs-node-ids-generated-by-the-hoopscommunicator-converter/2640/2).
