Convert to Polygon
Convert to Polygon (in Linework > Convert > To Linestring drop-down arrow) enables you to convert closed CAD polylines and Linestrings into Polygons. This command converts horizontal and vertical arc data to straight line segments in the process.
- Click in the Entity selection field and then in a graphic view select the data you want to convert. Click Options button for additional options.
- Optionally, check the Delete existing box to delete the source lines once they have been converted into polygons. Any lines not converted will remain.
- Optionally, check the Automatically close open strings box to use lines that are not closed to create a polygon.
- Under Chord Tolerances, select the following:
- Horizontal arc tolerance: The horizontal chord to arc tolerance used when converting arc data and linearising segments to straight lines.
- Vertical arc Tolerance: The vertical chord to arc tolerance used when converting arc data and linearising segments to straight lines.
- Under Polygon Properties, select one or more of the following:
- Elevation – Check this box to set the polygons to a constant elevation, if unchecked it uses the elevations of the original line.
- Name – Check this box to set the polygons to a new name, if unchecked it uses the name of the original line.
- Layer – Check this box to set the polygons to a new layer, if unchecked it uses the layer of the original line.
- Color – Check this box to set the polygons to a new color, if unchecked it uses the colour of the original line.
- Transparency – Set the polygon fill transparency value.
- Do one of the following:
- Click Apply to convert the lines and keep the Convert to Polygon command pane open.
- Click OK to convert the lines and close the Convert to Polygon command pane.
Note: To create polygons the seed lines need to be joined and the area covered by one line.
