Create/Update Projected Profiles

Icon:

Introduction

This command provides users with the ability to project String designs onto the alignment of other Strings to create Civil 3D Profiles (projecting design Civil 3D Profiles onto another alignment).

This differs from Superimpose Profiles - the software projects the design IP's onto the selected String (alignment) by calculating the chainage position on the String, then adds the vertical curves. Users can elect to transfer the vertical curve across without adjustement, or to project the start and end of the vertical curve geometry points.

For any Projected Profile being added, users can initially select the Profile Style and Profile Label Set to apply when they create the Civil 3D Profile. Once created, the software will update the profile geometry.

Strings can be created with any start/end chainage and in the opposite direction to the main String - the software will compute the relative IP chaianges, add the vertical curves and connect with tangents between the IP's.

Note: Assymetric vertical curves are not supported and it is assumed that parabolic vertical curves are used.

Common applications of this would be for designs where it is required to show the design profile for kerb returns that connect to a road, or there is an independent vertical design for the left and right side of the road that needs to be shown along with the design centreline on the same Profile View.

To apply this, there are two steps:

Create a Projected Profiles Group: this is a named group that can reference a source String and add other Strings as projected profiles
Add Strings as Projected Profiles: users pick any String, or auto add multiple Strings as projected profiles

Note: Once Projected Profiles have been added, the update will only recreate the vertical geometry.

Example Output

Projected Profiles can only be created from design Strings.

Details

Upon selecting the command the following form is displayed:


[List of Projection Groups]	Lists all added Projection Groups.
Add	Add a new Projection Group. A form will display for the group to be named. Once named, users can add any number of Strings (Profiles) to the group.
Delete	Delete the selected Projection Group.
Create/update All	Create/update all Projected Profiles
Selected Projection Group	Manage the projected profiles to be added and to which string.
Main Alignment	Select the main alignment to project the Strings onto as Civil 3D Profiles
Max. Offset	Set a maximum offset to search for the Projected Strings. Only Projected Strings located within the Max. Offset will be created as Civil 3D Profiles.
Search Side	Select Left/Right/Both for the side to search for the Projected Strings to include.
Civil 3D Styles
Profile Style	Select the main alignment to project the Strings onto as Civil 3D Profiles Click on Override Selected to apply the Profile Style to all selected Projected Strings
Label Set	Select the main alignment to project the Strings onto as Civil 3D Profiles Click on Override Selected to apply the Profile Label Set to all selected Projected Strings
Projected Strings	List of projected strings
[List of Controls]	Set the following for each Projected String listed: - Create: whether or not to create/update the projected profile - CSD String: Pick the CSD String to project. - Profile Style: Select the Profile Style apply to the Profile - Label Set: Select the Profile Label Set to apply to the Profile - Project VC Lengths: If ticked on, the verticla curve length is calculated using the projected start/end curve positions on the Main Alignment.
Add Automatic	Automatically adds related Strings (kerb returns are considered related strings, as are strings created from Variations that use a Profile). The default Profile Style and Label Set is used to add the Projected Strings
Add String	Add a single String to the list to be projected
Delete String	Remove a String from the projected profile list
Create/Update Profiles	Create/Update all Profiles for the selected Main Alignment (and Projection Group).
