Annotating Alignment Curve Data with InRoads

The NHDOT CAD/D staff is not proficient in all aspects of InRoads and is only documenting specific procedures as needed.
InRoads has been set up to work within the SS4 Workspace and utilize the projects MX file locations. Using InRoads as the native product to create and transfer horizontal and vertical alignments simplifies the process from MX. InRoads has no problems with USSF and alignments can have longer names than the four character MX label. InRoads uses the same dgnlib's for most features but has different Horizontal Geometry feature definitions pointing to InRoads native functions for auto annotation and use of InRoads tools for easier profile generation.

Alignment Curve Data

Alignments are stationed thru auto-annotation which also labels bearings and PT/PT locations. A separate process is used to annotate the Curve Data. Open the 12345-geometry.dgn's Default model where the alignments reside.

In order to annotate the curve data the alignment must have been exported to an alg file. Follow the process documented in Transfer Civil Geometry and Draw a Profile with InRoads if this has not already been done. InRoads utilizes InRoads Explorer for its native functionality. If the Explorer is not visible, Right-Click and hold in the Default view and select Explorer Show/Hide to un-hide the Explorer panel. Next, select the Geometry tab. The Geometry Tab is used to open or create Geometry projects (files). A project should already exist, use the Open command, select the saved alg file, Open, then Cancel. In the left pane expand the Geometry project and double click on the alignment to be annotated, setting it as the active geometry and displaying a red box around it.

Caption Text

In the top menu bar select Geometry > View Geometry > Curve Set Annotation... This will bring up the Curve set annotation box. Click on Preferences... and select the desired preference for the type of alignment (Mainline Alignment), Load then Close. Ensure the correct horizontal alignment is selected in the box and select Apply, and close. Your alignments curve data is now displayed. The text can be moved and rotated to the desired location.

Alignment Control Symbols

A minor bug exists such that the annotated alignment does not have PC/PT circles on those points. To place these circles on the alignment select Geometry > View Geometry > View Stationing. In the view stationing box select Preferences... then select the main o or other appropriate o preference, Load then Close. Ensure the correct horizontal alignment is selected in the box and select Apply, and close. Your alignment's PC and PT's should now have the cells placed on them.
