Creating Cross Section Detail Features

Detail cells are added to cross sections by a process that starts with creating plan view representations of the objects at even station intervals. A set of cross sections will be cut over this drawing and added to the other section layers.

Before You Begin

Before starting this process, make sure your display includes the Civil Geometry alignment that is to be used for referencing stations and terrain 3D points (12345-Ter-3DPts.dgn). You will need to create a report of the alignment and a station/offset report of the detail features.

Note that references to "12345" in file names refer to the project's five digit Project Number.

Create Alignment Report

If a 50' interval alignment report in .XLS format already exists, skip this section and continue to create the detail station & offset report.

Select the Horizontal Geometry Report button that is found on either the Analysis & Reporting or the Horizontal Geometry Task menus.

Horizontal report dialogFollow the Heads-Up prompt and select the alignment associated with the cross sections you wish to annotate. Click the Right Mouse (Reset) button to complete the selection process.

You will be prompted for the Start Station, End Station and the Interval. Confirm that the boxes on the Horizontal Geometry Reports panel for Lock to Start, Lock to End and Interval are all checked. Set the Interval value to 50.

If your alignment does not start at an even 50 value, uncheck the Lock to Start box and enter a start station that is at an even 50 foot value.

The last prompt looks for Profile information. This report does not need to have vertical information, so any response for this prompt will suffice. If there is interest in other reports beyond the scope of this procedure, then specify Active Profile so that the vertical component is included.

OpenRoads will open the Bentley Civil Report Browser and display the default horizontal report. This browser offers many predefined report options on the left side of the panel. The right side of this panel displays the output of the selected report option. From the left side of the report window, select the HorizontalAlignmentIntervalXYZ.xsl report.

When the report is displayed, select Save As... from the File menu. From the Save As panel, change the Save as type to XLS File (*.xls) and provide a File name. The report must have the correct station format before saving. Tools > Format options > Stations should be set to SS+SS.SS

Create Station/Offset Detail Report

Create the station/offset report by first selecting the point features to be reported. Note that only features which typically appear on cross sections will be processed. Those are defined in the cross section detail style set (crosssectdetail.pss).

This drawing of point features may have been created in different ways depending on the source of the data.

  1. MX Survey Data: For information processed through MX Survey options, the procedure for creating the point feature drawing is described in Convert MX Point Strings to Shared 3D Cells. Features can be selected by choosing elements from the appropriate levels.
  2. OpenRoads Survey Data: If the data recorder information was processed using OpenRoads, see Selecting OpenRoads Survey Point Features for details on selecting the necessary point features.

Once features are selected, choose the Point Feature Station Offset Elevation Report tool from the Analysis & Reporting task menu. You will be prompted to click on the alignment and then a data point to accept the selected detail features. When the default report appears, change the report to StationOffsetNorthingEastingElevationFeature.xsl. Use the Save As option on the File menu of the report window to save this report as an Excel (*.xls) file. Note that the default format is html and will need to be changed to xls.

Create Cross-Section Detail Drawing

Once the reports are created, the next step is to create a series of lines at the even 50' station which is nearest to each detail feature. When creating cross sections

Cross Section detail input dialog

Open a new drawing to contain these detail lines. Using the corridor drawing will keep items related to that corridor together, but they could also be put on a separate drawing if you prefer.

To create cross section detail features in OpenRoads, run the OpenRoadsXSDetail macro within MX. This creates short features which will be cut as a set of cross sections. Select the detail and alignment files created in the previous steps. Click Apply if you plan to do another alignment after or OK if this will be the only one processed.

Continue to follow the Create Cross Sections documentation.

The detail ticks that have been imported are Features. The feature names can be edited to include the + station value and description of the details they represent.

The point scan report will provide the station of the feature. Use element Selector to select each tick and edit the name in Element Info to include the station value.
