In most cases, you do not need to update polylines with CONVERT. By default,
the
PLINETYPE (page 1437) system variable specifies that polylines are updated
automatically when you open an older drawing. Polylines may be created in
the old format by third-party applications, and they may be contained in an
older drawing that was inserted as a block and then exploded.
NOTE Polylines containing curve-fit or splined segments always retain the old
format, as do polylines that store extended object data on their vertices. Editing
commands make no distinction between the two formats.
