Each line is processed as one cogo point. If the filter does not specify the point name, a name is generated in the same manner as the Add Cogo Point command. If station-offset data is provided instead of easting-northing-elevation data, an active horizontal alignment must be present. If a point’s station-offset data does not fall within the horizontal station range, the point will not be imported. Each cogo point is then added to the active cogo buffer and after all points have been added, the InRoads Explorer is updated.

Data Example - Point Name, Northing, Easting, Elevation

Cogo1 417289.44 194301.93 0.00

Cogo2 417233.32 194384.69 0.00

Each line is processed as a horizontal PI except the last line, which is processed as the last point of the alignment. As each PI is processed, it is added to an array. After all data has been loaded, each PI and related circular arcs and transition spirals is inserted into the newly created alignment whose name, description, and style were specified by the user through the Geometry Options dialog. After all PIs have been added, the alignment is inserted into the active Geometry Project in the InRoads explorer and made active.

Data Example - Northing, Easting, Radius, First Spiral Length, Second Spiral Length

The horizontal alignment data is PI based.

1000 1000

2000 2000 500 100 100

3000 1000 500

4000 2000 500 75 125

5000 1000

The preceding example is the same as adding PIs with the Geometry>Horizontal Curve Set>Add PI at the following coordinates:

1000, 1000

2000, 2000

3000, 1000

4000, 5000 and

5000, 1000.

Then using Geometry>Horizontal Curve Set>Define Curve to add the following curve sets:

An SCS type of curve set with a radius of 500, a leading clothoid spiral of length 100, and a trailing clothoid spiral of length 100

An SCS type of curve set with a radius of 500 without spirals

An SCS curve set with a radius of 500, a leading clothoid spiral of length 75, and a trailing clothoid spiral of length 100

Each line represents one horizontal event point. An active horizontal alignment must be present and only points that are within the station range of the alignment will be imported. Each successfully processed point is added to the active horizontal alignment.

Each line represents one horizontal regression point. The points are imported in the order in which they are listed in the file; no sorting takes place. Each successfully processed point is added to the regression buffer.

Data Example - Point Name, Northing, Easting, Elevation

2 417261.38 194343.31 0.00

A surface data file may contain only random point, breakline, interior, exterior or contour feature information and one file may not contain more than one type of feature data. Each line represents one point. As each line is processed, the point described in the line is evaluated. The wizard next takes into consideration the fence option and feature type specified on the Surface Options dialog. If a fence exists and the selection mode is not Ignore, the point is added to an array if it honors the fence boundaries. If the feature type chosen is Random all of the points are inserted at the end of the import process, otherwise, the pencode is processed. (If a feature type that requires a pencode is selected and the wizard does not define a column as containing pencode data, and error message is given and import aborts.) If the point read is the first point or if the pencode indicates that a new feature should begin, the feature name is updated by either the name provided or the seed name. Once the data for one feature has been read, the feature is added to the specified surface and the process continues until all features have been added.

Each line represents a vertical PVI except the last line, which represents the last point of the alignment. Each PVI is stored into an array as it is processed. After all data has been loaded, each PVI is inserted into the newly created alignment whose name, description, and style where specified through the Geometry Options dialog. The alignment is then inserted into the active horizontal alignment in the InRoads explorer and made active.

Vertical clothoids are not supported.

Data Example - Station, Elevation, Radius

Each line represents one vertical event point. If easting-northing-elevation data is provided, it is converted to station-offset data. An active horizontal alignment must be present and only points that are within the station range of the alignment will be imported. If the elevation is not given, it is calculated from the active vertical alignment, unless the point’s station is not within the vertical alignment’s station range, in which case the elevation is set to 0.0. Each successfully processed event point is then added to the active vertical alignment.

ASCII files can be imported with the Text Import Wizard by selecting Classic File as the Wizard Name on the Text Import Wizard. The data types supported by the Classic File import are:

Horizontal Alignment

Horizontal Event Points

Vertical Alignment

Vertical Event Points

This functionality is not available for Surface data or Horizontal Regression Points.

When you import a horizontal alignment, the alignment is added to the active geometry project. An imported vertical alignment is added to the active horizontal alignment. Cogo points and both horizontal and vertical event points are imported into the active point buffer. Refer to the documentation for File > Import > Geometry for more information.
