Surfaces

Each line will contain one data object (e.g. one point).
The data parameters for the object are separated by commas and are in the format:
NAME = VALUE
(e.g. X=123.456)
A line ending with a & means that it is continued onto the next line.
Data parameters are separted by a comma and can appear in ANY order.

Surface
The name of the surface, this is a text string enclosed by double quotes.

Layer
The layer name on which the point resides.
This layer name must appear in the list of Layers in the {LAYERS] section.
See Layers data format for more information.

MaskId
Aunique Surface id number.

MaxTriangleNum
The maximum triangle numberin the triangleset for this surface.

ContMinorInt
The height interval between minor contours in metres.

MinorContHeights
Optional, if present height values will be added as pieces of text at the start of each minor contour.
Note that the generated height text will be 'linked' to the contour polyline by the polyline entityid

ContMinorLayer
The layer name on which the contour resides.
This layer name must appear in the list of Layers in the {LAYERS] section.
See Layers data format for more information.

ContMajorInt
The height interval between major contours in metres.

MajorContHeights
Optional, if present height values will be added as pieces of text at the start of each major contour.
Note that the generated height text will be 'linked' to the contour polyline by the polyline entityid

ContMajorLayer
The layer name on which the contour resides.
This layer name must appear in the list of Layers in the {LAYERS] section.
See Layers data format for more information.

Number
Triangle number 1-n.

PTA
Each triangle consists of 3 points.
This is the first point number, it must be a valid point number in the [POINTS] section

PTB
Each triangle consists of 3 points.
This is the second point number, it must be a valid point number in the [POINTS] section

PTC
Each triangle consists of 3 points.
This is the third point number, it must be a valid point number in the [POINTS] section
