How to draw an area boundary for a linked file?

[parkside125]

Hi everyone,

I am trying to draw an area boundary of a linked file which has curves. I'll need to use 'pick lines' in order to draw the overall shape of this building.  Revit doesn't allow me to select the walls of the linked file. Does anyone know a way around this or is it something I have to do in the host file?  Thank you
