Re: get conection type and geometry between two elements from the model

Hi, 

What's your API problem to achieve your request? 

Revit API provides geometry related API to retrieve solid, face, edges and vertexes of element geometry:

Regarding connection of elements, for example, you can use BooleanOperationsUtils API to get the connection solid of wall and column and then use the geometry API to retrieve your desired geometric information.

Do you think this is helpful?
