A Surface is a collection of triangular faces. It has an area but no volume.
Two special types of Surface are TIN and Solid.
- 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.
