Getting Path Profile to recognise obstruction vector data

I know how to use obstruction vector data when running a View Shed.  But when I then attempt to run a path profile using the same data to look at the path to a specific point, the loaded obstruction vector data (representing a building) does not appear.  What am I doing wrong?
