Week 2 Challenge

1.What are workspaces and work sets? List Civil specific variables (min. 5). Where are the workspaces saved on computer (default location).

Ans: A Workspace is a place where the DOTs store their “Department Standards”, resources, libraries, and custom applications such levels, cells, line styles, feature definitions, macros (BAS/VBA/MDL), pen tables/design scripts, color table/book, unit definitions (miles/feet English vs. kilometers/meters Metric), Design Standards, seed files, etc. A Workspace is the “parent” of a Work Set.

A Work Set is the “Project” or plan set using the resources and standards of a Workspace.

Civil-specific variables:

1. CIVIL_CIVILTMDGNLIBLIST
2. CIVIL_DISALLOW_LOCKCHANGES
3. CIVIL_CIVILSETTINGS_READONLY
4. CIVIL_SHOW_SHARED_FEATUREDEF_PROPS
5. CIVIL_EXAGGERATION_VALUES
6. CIVIL_DEFAULTSETTINGS
7. CIVIL_DEFAULT_LINEAR_STROKING

Save Location:

Workspace Folder: C:\ProgramData\Bentley\OpenRoads Designer CE 10.10\Configuration\WorkSpaces

Workset Folder: C:\ProgramData\Bentley\OpenRoads Designer CE 10.10\Configuration\WorkSpaces\Training and Examples\Worksets

2.What are feature definitions? What is broader classification of feature definition types.

Ans: A Feature Definition controls how each feature is displayed and how it interacts with various tasks. The first time you use a Feature Definition it is copied into your active DGN and can then be modified.

1. Properties are used to define how a feature is to be displayed, annotated, computed, etc.
2. These are normally customized by each organization.
3. These are normally created in advance and propagated across an organization in order to standardize designs.

Types of Feature Definitions

3 types of feature definitions are supported depending on its type, a feature definition will have various properties that are available for definition.

Point Feature

1. R/W Marker
2. Control Point
3. Iron Pin

Linear Feature

1. Curb & Gutter
2. Wall
3. Ditch

Surface Feature

1. Existing Ground
2. Aggregate Base
3. Asphalt Pavement

3.Create a dgn file with 2D imperial seed file and 3D imperial seed file. Save it in project data folder, creating new folder named DGN from SEED.

Ans: Opening Open Roads Designer - Click on New File to open a window - Click on the 'Browse Option' adjacent to the Seed file to set the seed file - Select the 2D Imperial Design Seed File and Click open - Click on save to open the DGN file with 2D Imperial Seed File

Click on New File to open a window - Click on the 'Browse Option' adjacent to the Seed file to set the seed file - Select the 3D Imperial Design Seed File and Click open - Click on save to open the DGN file with 3D Imperial Seed File

4.Set geographic coordinate system to TX-83, North Central zone, US survey foot. Turn on the background imagery. Save this file with save settings.

Ans: Opening Open Roads Designer - Open a new file with a 2D seed file as shown below - Go to the 'Utilities' tab - Click on the 'Coordinate system' - Click on From Library and change the coordinate system - From Popup go to the Search tab and search for TX-83, North Central zone - Click ok to set the coordinate system - Go to view attributes - Set the background map as AERIAL - After setting the coordinate system and turning on the Background imagery

5.Attach the survey file from SURVEY folder to the newly created 2D dgn in above #3.

Ans: Opening Open Roads Designer - Open the file created with a 2D seed file - Opening Survey File - Go to the Primary tab and click on 'Attach Tools' - Click on References to attach the survey file - Click on 'Attach Reference' - Select the 'TOPO' file - Set Attachment method as interactive - Click open - Set the Logic name as Topo - Set Nesting as Live Nesting and set Nesting depth as 1 - Click on Fit view to fit the topo data in the screen -
