Cross Section Annotation Overview

This page is a general overview of the process of annotating cross sections generated by OpenRoads.

Introduction

After the Corridor is designed, Cross Sections can be generated. However if you want the sections to show more than just the proposed corridor and existing ground, other procedures will need to be followed. For a feature to show up in the cross sections it must be a 3D element.

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

For an introduction to preparing cross section drawings, see Creating Cross Sections

Annotate Cross Sections

Cross section detail features and text use Annotation Scale. The Annotation scale needs to be set for these elements to be displayed correctly.

  • Next, change the Drawing Scale to 1"=10'. This can be done from CADD menu > Settings > Drawing Scale.
  • Issue the Save Settings command and save the drawing.
Annotate Cross Sections Tool

Annotate Cross-Sections Tool

Select the Annotate Cross Sections tool to add annotation. The panel below will appear.

Annotate Cross Sections Dialog Box

Annotate Cross Sections Dialog Box

**Important** Select the name of the Cross Section Model (typically MCxM-Sections) created in the previous steps. Annotation will be added to the wrong cross sections if the correct model is not selected!

In the Surface section of that panel, select the Triangles or Name of the Corridor. Hit Preferences and choose the Preference you want to apply and click Load, then Close.

Preferences Dialog Box

Preferences Dialog Box

Each preference will have settings that apply to one or more types of section elements: points, features, or segments. The table below lists the folders of the Annotate Cross Section panel used by each Preference and examples of the features which will be annotated.

Preference Folders Annotate Crossing Features
1_Prop Slope & Supers Segments All Prop Top Line and Toe - No cuts or fills
2_Dimension Widths Segments Dimension points from corridor containing dimensions
2A_Dim Width & Extension Lines Features & Segments MC, Travel Way, Edge of Pave, Edge of Lane Excluding Shoulder and Slope Breaks - only use if not using 2_
3_Exist Feature Labels Features All Exist Features including environmental and right-of-way items
4_Prop MC Elevation Features Proposed Alignment Elevations (MCxM.MCxM)
5_Exist Sect Elevation Features Existing Centerline Elevation feature - Sect ExistElev. For more details, see Annotating Existing Elevations
6_Prop Ditch Elev Features Slope Ditch Front

Once the Preferences panel is closed, the Annotate Cross Section panel will be active again. Selecting a folder will expand it's content. A checkmark will appear (top center) if that folder's properties are defined for that preference.

 

Annotate Cross Section Dialog Box

Annotate Cross Section Dialog Box

Select the Annotate entry under a particular folder to bring up the list of crossing features that could be annotated.

Annotate Cross Section Selected Dialog Box

Annotate Cross Section Selected Dialog Box

Highlight the Crossing Features you want to annotate (see table above for suggestions). Crossing Feature selection is done while holding the <ctrl> key and mouse clicking or click and drag. Review each folder: Points, Features, and Segments and each Annotate tab under those folders for correct feature selections before clicking Apply. Note that the Crossing Feature list is presented in a random order and, at present, there is not an option to sort it.

It is suggested that you save the drawing between each successful annotation. Take extra care if a mistake is made since using the Undo tool will undo all annotation placed since the box was opened or the last time the drawing was saved.  

Repeat by Selecting the next Preference, open the appropriate folder (Points, Features or Segments) on the Annotate Cross Section panel, select the Annotate tab, highlight the Crossing Features. Click Apply.

Sample Cross Section

Sample Cross Section

In previous versions of OpenRoads, sections were exported as MicroStation drawings to be edited. This is no longer the case. This drawing can be opened and modified in MicroStation as well as MX to (re)create End Area Volumes, if updates or hand drawn corrections to components have taken place. When the drawing is opened via MicroStation, the MicroStation cross section task menu (nhXSU10) will be displayed because the drawing name has "XS" in it.

Model Properties

Model Properties

Use the Models > Edit Model Properties tool to change the model type to Design, uncheck Propagate Annotation Scale and change the setting for Line Style Scale to use the Global Line Style Scale which should = 1.

The XS-Edit OpenRoads Macro from the NHDOT dropdown menu should also be run to change some text levels and replace some of the labels with the proper text.
