Polygon Item Properties

A Polygon consists of one or more closed 'loops' and can be coloured in by setting its Brush property.

You can create a Polygon by using the Polygon command: Polygon (Create > Simple).

Some Boolean operations do not work with self-intersecting geometry. We recommend you avoid creating such Polygon items Use Simplify to fix up self-intersecting geometry.

• Number of loop edges: _numedges&
  The number of edges in a geometrical shape.
  
  
• Number of loops: _numloops&
  The number of loops used by a Polygon item. Most Polygon items have only one loop. However, any holes or islands will be stored as extra loops.
  
  
• Opaque: _text_opaque&
  Should text be drawn with an opaque background? True/False
  
  
• Orientation: _orientationDeg#
  The orientation angle of the Polygon, in degrees.

  The size of the item in the Z direction, in metres.
  
  
• Splinter factor: _splinter#
  The splinter factor of the Polygon. A circle has a splinter factor of 1. A very long and thin area could have a splinter factor of 100. Polygon items with large splinter factors are often produced by overlapping lines which are almost by not quite the same.

• Thin in Y: _thinY&
  Does all the geometry in the item have the same Y coordinate?
  
  
• Thin in Z: _thinZ&
  Does all the geometry in the item have the same Z coordinate?
  
  
• URI (Hyperlink): _URI$
  The Uniform Resource Identifier (URI) associated with an item, which allows you to link to an object. This object could be a web page, or an application.
  
  
• Underlined: _text_underlined&
  Is the text drawn underlined?
