Custom Weldment issues

All,

    I am trying to build my first custom weldment profile and I am getting some issues.  When I go to use the weldment I am getting an error that states the library feature is empty.  When I open up the SLDLPF file it is not empty.  I have constructed it in a sketch, saved it from the sketch to the library, but I still get this error.  I have attached the sketch here to this thread.  I have watched several youtube videos on how to do it, but it is still not working and at this point I am not sure what I am doing wrong...I would greatly appreciate some pointers as to what I am doing wrong...

Thank you everyone...

Keith
