4. Chord Tolerances:
   • Horizontal arc tolerance: This is the horizontal chord to arc tolerance used when converting arc data and linearising segments to straight lines.
   • Vertical arc Tolerance: This is the vertical chord to arc tolerance used when converting arc data and linearising segments to straight lines
5.  Polygon Properties:
   • Elevation – Check this box to set the polygons to a constant elevation, if unchecked it will use the elevations of the original line.
   • Name – Check this box to set the polygons to a new name, if unchecked it will use the name of the original line.
   • Layer – Check this box to set the polygons to a new layer, if unchecked it will use the layer of the original line.
   • Color – Check this box to set the polygons to a new colour, if unchecked it will use the colour of the original line.

6. Do either of the following:
   • Click Apply to convert the lines and keep the Convert to Polygon command pane open.
