The Draw | Tools | Break Apart command is used to separate a metafile into its component parts. The Break Apart command allows you to manipulate a .WMF or an .EMF object if the Break apart metafile option in the Windows Enhanced Metafile Import Options dialog or Clipboard Formats dialog was not selected. After selecting Draw | Tools | Break Apart the image is represented as a group of drawn objects, such as polylines, polygons, points, and text. The Break Apart command is also available by right-clicking the metafile and selecting Break Apart Metafile.
