Inserting an external feature into a part file

 

Insertin, using the library, copy paste and all other attempts have failed. I have a plastic doghouse I want to use in multiple places in my frame. As a kind of side poject i though i would do it using a library item. Any suggestions on how this can work would be most appreciated. Attache dimage is the way i started to do it and id probsbly the way I will finish.
