MapInfo Pro: How to smooth a polyline permanently

MapInfo Pro's Fix/Clean > Smooth Lines (64-bit) or Object > Smooth (32-bit) only smooths a polyline for display.

To permanently smooth a polyline, in MapInfo Pro 64-bit, use
  •  SPATIAL > Modify > Spline (ensuring MapCAD is loaded first via HOME > Tools > Running)
  •  if Discover add-on is available, use MODIFY > Lines > Smooth Lines
in MapInfo Pro 32-bit, use
  • MapCAD > Spline (Load MapCAD from Tools > Tool Manager)
  • if Discover add-on is available, Discover > Object Editing > Polyline Smoother
