Insert a zone

Steps:

1. Run the laZonify command. Select one of the two options in the command line to insert the Zone object:
   • Pick inner point: click inside a closed boundary of 2D curves.
   • Boundary curve: select a closed and planar curve.
2. After the first step, the Zonify insert dialog box will appear. This dialog shows the basic options of the Zone object in two tabs:
   • Zone: zone parameters.
   • Material: material settings for the Zone object.
   Choose the basic insert options. Press ENTER, ESC or right click to exit the dialog.
3. Pick a point to insert the Zone label.

A zone can be also created when adding a division on a terrain, which is generated with the following commands:

• laTerrainDivide
• laTerrainAddCutAndFill
• laTerrainAddHole
• laTerrainAddPath

Control points

The Zone object has the same control points as the curves used to generate it.

In addition, it has a Control arrow to move the Zone surface and a Control arrow to move the zone Label.

To turn a Zone object control point on run the PointsOn command (or press F10) and select the Zone object. To turn its points off, press the Esc button or run the PointsOff command.
