Convert 3mx to Esri Arcmap multipatch

I created a 3mx file and would like to convert it into an ESRI multipatch feature,  I know that you can output a  scene layer package but as far as I know this is for loading into ArcGis Online

I wanted to create a multi-patch in a file geodatabase.  Arcmap will convert an obj or Collada dae file but both of these have no spatial reference when exported from Context Capture. Any suggestions would be appreciated
