Converts a specified DGN reference into a block, making it a permanent part of the
drawing. The DGN-dependent named objects (such as layer names) of the former DGN reference
are added to your drawing. In each DGN-dependent named object, the vertical bar (|)
is replaced with three new characters: a number (usually 0) between two dollar signs
($). The number is increased if the same name already exists in the current drawing.
