Parcels
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.
Each parcel requires a header block of data:
Each line requires a "From" Point, "To" point, Bearing "Brg" Distance "Dist".
The bearing is in the form of degrees, minutes and seconds right justified.
Distances are in metres.

Plan
Mandatory. This must be the name of the Plan as specified in the [PLANS] section
It can be any Alphanumeric string of characters
Lot
Mandatory. This is the lot name/number as specified on the plan.
It can be any Alphanumeric string of characters
UserId - Locality
Optional. This can be the user who entered the parcel, or can be used to record a locality number.
CentroidX, Y
Optional. This the Easting/Norhing value of the parcel centroid in metres.
Area
Optional. This is the Stated/Plan/Legal Area and is not the computed area.
LotType
Optional. This is a number (usually 1-1000) indicated the usage of the lot.
See the 'Parcel Tags' in online help for more details
Lot Accuracy
Optional. This is a number 1-7 indicating the relative lot accuracy.
See online help for 'Accuracy Rules' for more details.
AnglesMode
Optional. Y Indicates the data was entered in angle mode.
Historical
Optional. This indicates the parcel is not part of the 'current' parcel network.
It indicates an Historical parcel which has been superceded or subdivided.
Compiled
Optional. This indicates the parcel is compiled from other plans.
Joined
Optional. This indicates the parcel is joined to the parcel network and the point numbers
in this parcel refer to the point numbers in the [POINTS] section.
If not present, the parcel is unjoined.
Unjoined parcels always have 'local' point numbers (1-n) which are not points in the [POINTS] section.
Locked
Optional. This indicates the parcel is locked in the database and can be edited in this file.
Note: This value is not used, it is obsolete
Default = Y
Unclosed
Optional. If present, the parcel is not closed.
Entity
This is a unique id number for the parcel.
It can be used in Text items to relate the text to a parcel by the entity number
Group
This is a number which 'groups' unjoined parcels together as a set using common point numbers.
This facilitates joining a group of parcels in one operation.
DBParcelid
Optional. If present, it is the database parcelid.
This can be used to identify a database parcel during a database update even if the parcel name and plan have changed.
StartBearing
Optional. Used in Angles mode as the starting bearing in the format DDDMMSS.SSS.
BacksightBearing
Optional. Used in Angles mode as the backsight bearing in the format DDDMMSS.SSS.
Closing Angle
Optional. Used in Angles mode as the closing angle in the format DDDMMSS.SSS.
ClosingBearing
Optional. Used in Angles mode as the starting bearing in the format DDDMMSS.SSS.
ParcelScale
Optional. This is the computed parcel scale factor from the Least Squares Adjustment as a number (1.00000) with 6 decimal places.
ParcelRotation
Optional. This is the computed parcel rotation from the Least Squares Adjustment in the format DDDMMSS.SSS.
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.
Parcel Lines
Each parcel can have any number of lines
From
The Start point number for the line.
If the parcel is joined, this is a real poin number.
To
The End point number for the line.
If the parcel is joined, this is a real poin number.
Brg
The bearing for the line in the format DDDMMSS.SSS
Dist
The length of the line as number with 6 decimals.
Distance values are always in Metres even if the Plan units are Feet or Links.
CentrePt
The the line is a circular curve this is the centre point number.
Radius
The the line is a circular curve this is the radius in metres.
Type
The line type as a number (0-1000).
See the online help 'Parcel Types' for an example.
Category
This value groups some line types together by category.
0 - Boundary
1 - Dependent
2 - Precise Connection
3 - Connection
4 - Radial
5 - Road
6 - Origin Connection
7 - Part Connection
LineAccuracy
The line accuracy is computed by the Least Squares Adjustment
See here for more info on accuracies
Value is 0-7
Default = Parcel Accuracy.
Angle
In angles mode, this is the Angle at the end of the line in the format DDDMMSS.SSS.
RefPt
In Angles mode, this is the reference point for this line.
LineString
The line string group number.
LinePoint
If the line is a LinePoint line, this is the line point number.
A LinePoint line indicates that the specified LinePoint lies on the line FromPt - ToPt.
Radius
The the line is a circular curve this is the radius in metres.
