I have a .rvt file in which I can extract 3D objects and metadata properties that belongs to floors.
The images contain the floor 2D design

I want to extract from any floor, for example, the one selected in red, the shape of the floor itself or its object.
The selected floor has this metadata

that allows me to identify in the json file, that correspond to its metadata, the properties of this component(externalId and objectId)

How can I do this with the forge API Endpoints?
Is there is any endpoint that allows me to do this?
