Strings

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.

Strings consist of a sequence of point numbers (e.g. PT=11) which define the string. GeoSurvey will draw the string as a line joining each point in sequence. Additional parameters may be added in the sequence.
Thus "...,PT=245,CPT=130,PT=246,..." describes a circular arc starting at point 245 suing a centre point of 130 and ending at point 246. Note that arcs are always clockwise and have a maximum size of 180 degrees.

Name
The string name is a text string enclosed by double quotes.

Type
The string type must be one of the following:
Some of these strings are treated in special ways by GeoSurvey. E.g. Lots are always closed and can have the area computed and displayed at the centroid of the lot.

Style
This is a number 0-60 which is the line style, dotted, dashed etc. Note: If no line style value is specified, the default layer line style will be used.
See Line Styles for line styles information.


Colour
The colour to be used for the string lines, this must be one of the standard Colours. Note: If no colour value is specified, the default layer colour will be used.
See Colours for format information.


FillColour
The colour to be used to colour in the string if it is closed (e.g. for lots). This value must be one of the standard Colours. Note1: If no colour value is specified, the string will not be coloured in.
See Colours for format information.


Thickness
The line width in mm to be used for the string lines, this should be in the range 0.1mm to 5mm. Note: If no thickness value is specified, the default layer thickness will be used.

X
The Easting or X value for the string cendtroid.

Y
The Northing or Y value for the string cendtroid.

StartChainage
This is the starting chainage value for the first point bin the string. This is usually used for Roads, Drains and Sewers so that GeoSurvey can assign correct chainage values to points on the string

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


FontName
The name of the Windows font to be used when displaying the string name and/or area. Note: If no font name value is specified, the default layer font will be used.

FontColour
The colour to be used for the string text such as the name and area. This must be one of the standard Colours. Note: If no colour value is specified, the default layer colour will be used.
See Colours for format information.


FontSize
The size of the text in mm to be displayed when plotted at the Job Plot Scale (see Job Settings). Note: If no font size is specified, the default layer font size will be used.

Discontinuity
This is a Y/N value to indicate the string is a discontinuity or breakline. This will be used by the triangle formation so that no triangles will be formed across the string

Entity
This is an internal id number for the string. It is sued to link text items such as the lot number sytring and area string to the lot. When a lot is edited, it's mname and/or area may change and the lot name and area text strings must be updated. This id number is used in those text strings as 'AssocEntity' to link the two items.

PT
This defines a point number on the string. There is no limit to the number of points in a string.

CPT
This defines a centre point for a circular arc. It is placed between two PT=x values.

SegType
This can have the value 'Arc' or 'Spiral-Clo'. If omitted, it is assumed to be a circular arc.

Rot
defines the direction of rotation of an arc or spiral.

ShortLine
This is a Y/N value to indicate this line segment is a 'short line' and will be added to the Short Line Table in the Annotated Plan.

StRadius
For a Clothoid Spiral, this is the radius at the start of the spiral.

EndRadius
For a Clothoid Spiral, this is the radius at the end of the spiral.

Len
For a Clothoid Spiral, this is the length of the spiral.

ExtAttName
An extended attribute has three values, this is the name of the item, a text field.

ExtAttValue
An extended attribute has three values, this is the Value of the item, a text field.

ExtAttType
An extended attribute has three values, this is the data type of the item, a text field.
The values can be VT_I2, VT_I4, VT_R4, VT_R8, VT_DATE, VT_BSTR.
