NAMED BOUNDARIES
OpenRoads designer uses MicroStation Named Boundaries to define plan, profile, and cross section clipping areas. The Named Boundaries tools will create Drawing and Sheet models needed for plan, profiles and cross section contract sheets. Sheets are generated in their own design file. Files can be created using seeds found in the CTDOT DDE Configuration.
Sheets are clipped using Named Boundary tools from the OpenRoads Modeling workflow on the Drawing Production tab.
The top of the dialog contains several icons to select the type of named boundary that you wish to place.

CTDOT has configured sheet clipping options for plan, profile, and cross section sheets with common scale options. These configurations are stored in DGN Libraries and will appear in the Drawing Seed drop down menus, see below.
A sheet design file is created to house the named boundaries as well as the completed sheets. The various base model design files required to assemble the sheets are attached as reference files to the Design Model in the sheet design file. The named boundaries are placed in the design model relative to a selected alignment, profile, or 3D model for cross sections.
PLAN AND PROFILES
Examples showing four named boundaries placed for the plan and profile sheet production are shown below.
Tip: When the file containing the existing ground terrain is attached, setting the terrain active is necessary to display the existing ground profile on the sheets. When the terrain model is set active, a 3D model is created in the active file and attached as a reference to the plan view. The 3D model is typically not needed for plan and profile sheets and the display should normally be turned off in the when the sheets are generated, the software creates a MicroStation drawing model for each named boundary, plan, profile, or cross section. An example of the drawing model for a plan view named boundary is shown below.
The drawing models are referenced to a sheet model with a sheet border to assemble the completed sheets for PDF generation as shown in the example below.
The sheet model is intended for PDF generation. Most annotations should be placed in the various drawing models, not in the sheet models.
CROSS SECTIONS
Cross-section sheets are generated in their own design file. Within this file, OpenRoads designer uses MicroStation Named Boundaries to define cross-section clipping locations.
Before generating the named boundaries, a design file is created to house the cross-section sheets. The various base model design files required to assemble the cross sections are attached as reference files to the Design Model in the design file. The 3D model must be displayed. The cross section is cut from the 3D model. In the example below, the geometry, survey, and corridor model base models are attached to the plan view with the 3D model displayed. The named boundaries are placed in the 3D model relative to a selected alignment like the example below.
When the sheets are generated, the software creates a MicroStation drawing model for each named boundary. An example of the drawing model for a cross-section is shown below.
The drawing models are referenced to a sheet model with a sheet border to assemble the completed cross-section as shown in the example below.
The sheet model is intended for PDF generation. Most annotations should be placed in the various drawing models, not in the sheet models.
