Hi,
Unfortunately, as I know there is no API function that you can simply check touch/cross/near between elements.
You can use ACAPI_Element_GetRalations() to check between beams but not work for beam to object, for example.
Using solid operation functions can be a workaround for different types.
But for checking 'near', the only idea come to my mind is to get 3D element polygons and check the distance between polygons one by one by yourself.
