MEP Space class Room property returns null with linked models

grahamcook — Mon, 08 Oct 2012 13:29:25 GMT

All of our projects use a separate MEP model that has the Architectural model linked. We need to copy through and manage some of the custom room parameters stored in the Architectural model for which I'm writing an Addin.

The first task would be to establish what room a space is associated with for which the Space class has a Room property. This however returns null if the room is located in a linked model. So I need to establish another more cumbersome method of matching up a Space with a Room, maybe comparing their geometry's? Any suggestions would be greatly appreciated.

Forgot to mention that the company i'm working with don't use the built in room number parameter, they use their own. So i wouldn't be able to match the room numbers.

Hi grahamcook,

What about Document.GetRoomAtPoint((space.location as LocationPoint).Point) ?

Or Document.GetSpaceAtPoint((room.location as LocationPoint).Point) ?

Hope it helps with linked files...

Cheers,

Yes, I would suggest using the methods mentioned by Revitalizer, *in the linked document*.

So you may have to translate the coordinate values from the container project to the linked project.
