Import CAiCE Files (.txt)

Import Computer-Aided Civil Engineering (CAiCE) files (such as those used by various Departments of Transportation (DOTs)) to bring station, offset, and elevation data from road cross-sections into your project. Generally, this data comes as a zipped set of related files.

Note: Each set of related files should be imported at the same time so they are co-related. Horizontal alignment (HAL) files can be imported independent of their related vertical alignment (VAL) and cross-section files, but VAL and cross-section files must be imported concurrently with HAL files to display properly.

To attach cross-sections to the real alignment:

Cross-sections are based on the XYZ position specified at the center of each cross-section. You can revise the stored cross-sections to use the curvilinear alignment if you have it.

  1. Drag and drop the centerline file onto your project.
  2. Select just the stored cross-sections.
  3. Edit their properties and change the HAL to be the centerline you just imported.

Errors:

  • If offset points are not listed in left-to-right order, it is considered an error, but the order is not changed. Cross-section points will be connected in a zig-zag manner. Request a corrected file before before you use the data.
  • If the ends of the cross-sections do not intersect the existing ground, it is considered an error. Request a corrected file before before you use the data.

Importable Data

Data in the file

How the imported data is handled

HAL file (.asc)

 

A HAL ia created by connecting the centers of the cross-sections.

A corridor is created with the existing ground set as a reference surface. A template is created using the proposed ground as a surface. Run a Corridor Earthwork Report to get volumes based on the stored cross-sections.

VAL file (.asc)

 

A VAL file is not required, as the imported cross-sections have elevations.

Cross-section file (.soe)

Station Offset Elevation

Stations, offsets, and elevations are used to form cross-sections along the HAL.

The original data and design data are in the same file:

  • The existing cross-sections are stored on a layer and a surface is created.
  • The proposed cross-sections are stored on a layer and a surface is created.
