get ceiling material in room

CADdaddy.com — Tue, 14 Feb 2017 01:30:04 GMT

Hi all,

I'm using the SpatialElementGeometryCalculator to access the 3D faces within a room. It finds the walls, floor, and the floor above but the ceiling 3D face seems to be completely ignored. Anybody know how to acquire the ceiling(s) in a room? Better yet, is there a way to acquire everything that is in a room using the boundries provided by the SpatialElementGeometryCalculator?

Dear James,

Thank you for your query.

Have you taken a look at the RoofsRooms SDK sample?

It detects whether a room has a roof.

You may be able to adapt it for ceilings also.

Alternatively, you should be able to shoot a ray upwards from the floor of the room using a ReferenceIntersector, and the ceiling should be the first element you hit.

I hope this helps.

Best regards,

Jeremy

Dear James,

To address your second question how to "acquire everything that is in a room":

The ElementIntersectsSolidFilter class should help with that:

You could create a solid representing the room shape and retrieve all elements intersecting that solid.

I hope this helps.

Best regards,

Jeremy
