Options

The following properties allow control of the import.

General	Description
Layer as	Code - Use the code of imported objects as the layer. Layer - Use the layer of imported objects as the layer.
Import Measurements	Select to import measurements.
Process Codes	Select the checkbox to process feature codes, control codes and string numbers to create lines and polygons.
Join Consecutive Points	Select the checkbox to join all points with the same code that are measured consecutively.
Control Codes	Select the control code table to be used to process codes.
Measurement Date Attribute	Enter a name for the attribute that will hold the measured date and time for imported points.
Transformation	Description
Apply Transformation	Do one of the following: Select Yes (Scaled) to compute a scaled transformation using points with the same name and apply it to all points in the imported file. Select Yes (Unscaled) to compute an unscaled transformation using points with the same name and apply it to all points in the imported file. Select No to import the points in the file without a transformation. Note: A 2D Conformal with Height transformation is computed if at least one matched point pair has known heights. A 2D Conformal transformation is computed if all matched point pairs have at least one unknown height.
Save Transformation	Select the checkbox to save the computed transformation to the project.
Points	Description
Name Format	Add a prefix or suffix to rename points imported from the file. Note: {0} represents the current point name. Type a character before {0} to add a prefix. Type a character after {0} to add a suffix.
Name Offset	Add a numeric offset to the numeric component of the names of imported points.
Adopt Existing	Do one of the following to manage points with the same name: Select the checkbox to adopt a point in the project in preference to importing a point from the file when points with the same name are encountered. Clear the checkbox to import all points from the file. Points with the same name may be created in the project.
Lookup Tables	Description
Layer	Select the Layer lookup table to be used during the import.
Attribute Definition	Select the Attribute Definition lookup table to be used during the import.
Plan Symbol	Select the Plan Symbol lookup table to be used during the import.

A blank selection for a lookup table indicates that no lookup will be performed.

Notes

Objects that can be imported from Topcon Magnet XML include: DesignPoint, Polyline, Breakline, Area, Circle, Arc, TextLabel and Surface.
If Process Codes is selected, feature codes, control codes or string numbers will be used to create lines and symbols.
If consecutive points are joined on import, points with the same code are joined when the layers Intended Use is set to Lines or Polygons, providing the point is not already part of a line sequence created from control codes or string numbers.
Process Codes is enabled when Code is selected in the Layer As control.
Arcs are imported as 2D circular arcs with heights in a line object.
Linework is imported when Process Codes is not selected.
Lines created during code processing inherit the attributes of the first point in the line.
If a line created by code processing is intended to be a breakline, prior to import, in the layers General tab, set Breakline to Yes.
Lines marked as breaklines in the imported file have the breakline attribute set to Yes.
Vertical angles are imported as zenith angles.
The name of the saved transformation file is included in the import report.
Point name matching is performed prior to re-naming.
Transformations are computed and applied only when measurements are imported.
A "00" string at the end of a code indicates codes of the same type will not be joined regardless of the layers Intended Use.
A total station setup summary displays when TPS measurements are imported. Differences larger than the allowable tolerance display in red.
