Item Properties

Properties

• Area: _area#
  The area covered by the item in square metres.
  
  
• Blended Colours: _bBlend&
  Should the colours of a Surface item be blended between nodes?
  
  
• Clockwise: _bClockwise&
  Is the item geometry defined in a clockwise direction?
  
  
• Number of edges: _nEdge&
  The number of visible edges in a Surface.
  
  
• Number of nodes: _nNode&
  The number of nodes in a Surface.
  
  
• Smooth: _bSmooth&
  Do any Surface vertices have their own normal, i.e. does the Surface draw smoothly?
  
  
• 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.
