How to make beam as room boundary

[Anonymous]

Beam also have attribute "WALL_ATTR_ROOM_BOUNDING" like Wall or Column,why beam can't be set as room boundary?

when I use code:

bool a= beam.get_Parameter(BuiltInParameter.WALL_ATTR_ROOM_BOUNDING).Set(1);

the parameter is not read-only,return a is false.

but,when I set wall or column,return true.

So,is there anyway to make it successful?

Have you tested whether that really works at all?

Try it out manually in the user interface first, before trying to program anything.

If it is not supported in the UI, the API will not support it either.

Cheers,

First,it doesn't show in attribute column,so I can't try it out manually in the user interface.Some attribute doesn't show in attribute column,but I can still make it work by programming. However,the attribute is not.Maybe the attribute is just a invalid parameter ,I think.
