can't import sketchup symbol into X1

[lighthouse]

Hi,
Having read the forum, it says you can drag an skp file into an X1 plan and the symbol will appear. When I do this nothing happens (no symbol). Also, under the file menu (import) there does not seem to be anything to suggest importing a model (as opposed to a dxf, dwg, etc). Can I import skp files into X1, and if so, how? Thanks much!
