LINEAR TEMPLATES
Linear Templates can be placed along a civil geometry element without a defined corridor. The "Apply Linear Template" tool will apply a template to a selected civil geometry element that has a profile associated with it. Most templates can be treated as linear templates like shoulder, curb, etc. and don’t need a defined corridor to be placed. Once you have the profiled linear element (3D geometry), templates can be placed. After placing the template, a corridor for the linear template will be automatically generated. This corridor and linear template can be edited as needed.
The Apply Linear Template tool can be found on the OpenRoads Modeling workflow Ribbon:
Model Detailing Tab > 3D Tools Group > Apply Linear Template
Apply Linear Template will activate the Pick Template dialog then inserts the chosen template into the drawing relative to the selected linear element.
The Connecticut DOT has provided range of Linear Templates within its workspace. See figure below.
For more information on Templates, see Section 3 - The Template Library
For Swapping and Editing Linear Templates, see Swap Out or Edit the Linear Template under Module 6 - Placing Civil Cells.
SURFACE TEMPLATES
Terrain Models either existing or proposed do not have depth or material associated with them. A Surface Template is made up of various components and each component can be of various depth and is applied to a terrain model. Components for a surface template are closed shapes such as asphalt layer, aggregate layer, grass layer etc. The "Apply Surface Template" tool will apply a selected surface template from the template library to a terrain.
The Apply Surface Template tool can be found on the OpenRoads Modeling workflow Ribbon:
Model Detailing Tab > 3D Tools Group > Apply Surface Template
Apply Surface Template will activate Pick Template dialog, then insert the chosen surface template into the drawing relative to a terrain model.
The Connecticut DOT has provided range of Surface Templates within its workspace. See figure below.

CIVIL CELLS
A civil cell is a collection of civil elements - geometry, templates, and terrain models - which can be placed repeatedly in a design. The collection of civil elements will have been created relative to one or more reference elements. When you place the civil cell, you choose the new reference elements, and a new collection of civil elements is then created relative to them. A civil cell can therefore be thought of as a copy of the original collection of civil elements, relative to the geometry of the new reference elements. Civil cells can be 2D or 3D. They can consist of 2D (plan) elements only, or 3D elements (2D elements with profiles), and can include terrains, linear templates, area templates, and simple corridors.
When the new civil elements are created, all the rules associated to them are also created. This means that the new civil elements retain their relationships, both with each other and with the reference elements, and therefore know how to react when these relationships change. In addition, the Civil and MicroStation toolsets can still be used on the new civil elements, to adjust and further refine the design as required, because there is no difference between a civil element created by a civil tool, and one created by placing a civil cell.
Civil cells can save a lot of time and effort, because they replicate the complete series of steps needed to create the civil elements. They also help to ensure compliance with design standards, by making a civil cell available to the design team.
NOTE: Driveway Civil cells provided by CTDOT are only for simple repetitive geometry and are not intended for complex geometry.
Before placing civil cells, users are encouraged to complete the Using Civil Cells in OpenRoads Designer training course under 01 - OpenRoads Designer - Roadway Design & Modeling - Intermediate » (CONNECT Edition - English - Fundamental) on the Bentley LearnServer.

See Module 6 - Placing Civil Cells for instruction to Place and edit Civil Cells.
This guide will not document each tool that is available in the OpenRoads Modeling interface. See the Bentley Online Help for commands not detailed in this document.
Quick Access ToolBar
Activate the OpenRoads Modeling workflow from the pick list next to Quick access toolbar in the upper left corner if it is not already active. The ribbon menu will reflect the OpenRoads Modeling tools.
Ribbon > Model Detailing Tab
Place Civil Cell – This will activate the browser to select the civil cell to be placed. Civil cells can be selected from the active drawing’s graphics, or from the browser that provides a schematic preview of available civil cells from all design models in the current drawing, or via the currently defined configuration.
Create Civil Cell – This will activate the command to create civil cell. It prompts you to name the new civil cell and select reference elements. The dependent elements are identified and highlighted for verification.
Process Civil Cell – This will reprocess all linear templates and templates for the selected civil cell. This may be necessary where the active terrain has been changed or where reference file interaction needs to be refreshed.
Drop Civil Cell – This will activate the drop command and targets civil cells.
The standard MicroStation Drop command works on civil cells, but selection is dependent on element priority in the model and may require element cycling to select the civil cell.
