What is a corridor in Autocad Civil 3D?

What is a corridor in Autocad Civil 3D?

A corridor model builds on and uses various Autodesk Civil 3D objects and data, including subassemblies, assemblies, surfaces, feature lines, alignments, and profiles. The corridor manages the data, tying various assemblies (applied for different ranges of stations) to the baselines and their finished grade profiles.

How do you connect two corridors in Civil 3D?

To Merge Corridor Regions

  1. In the drawing, click a corridor.
  2. Click Corridor tab Modify Region panel Merge Regions Find.
  3. In the drawing, select the first region you want to merge. The selected region is highlighted gray.
  4. Select the next region you want to merge.
  5. Do one of the following:

What is vertical alignment in Civil 3D?

The vertical alignment, called a profile in Civil3D, is the centerline of the roadway viewed from a profile (or side) view and consists of tangents (grades) and curves. The curves in a vertical alignment differ from the horizontal alignment curves in that they are parabolic curves instead of circular curves.

What is a corridor surface?

You can create a surface from a corridor. Because corridor surfaces are an output of a corridor model, they remain dynamically linked to the corridor. Any changes to the corridor definition are reflected in the surface definitions. You can also create a detached surface from a corridor surface.

What is Assembly road?

An assembly is an Autodesk Civil 3D drawing object (AECCAssembly) that manages a collection of subassembly objects. Together, assemblies and subassemblies function as the basic building blocks of a roadway or other alignment-based design.

How do you add an intersection to an existing corridor?

Select an intersection object, and then click Intersection tab Modify panel Recreate Corridor Regions Find. The Intersection Corridor Regions dialog box is displayed. On the Intersection Corridor Regions dialog box, select one of the following: Create a New Corridor or Add to an Existing Corridor.

What is a layout profile?

Use. You can assign a special layout profile to folders. This gives a folder its own layout. If you navigate to this folder in the folder hierarchy, the layout changes within the iView.

How do you turn a corridor into a surface?

To create corridor surface:

  1. Select corridor and open the corridor properties.
  2. In the Corridors Properties dialog box, click the “Surfaces” tab.
  3. Use the “Create a corridor surface” button and name the surface.
  4. Within the “Add data” section, set the “Data type” and “Specify code”.

How do you create an assembly?

To create an assembly

  1. Click Home tab Create Design panel Assembly drop-down Create Assembly Find.
  2. In the Create Assembly dialog box, in the Name field, enter a name for the assembly.
  3. For Description, enter an optional description of the assembly.

How do you add a point of intersection in Civil 3d?

Click the Home tab Create Design panel Intersections drop-down Create Intersection Find. You are prompted to pick an intersection point in the drawing. In the drawing, click the location in the drawing where two alignments intersect.

How do you associate an alignment with a surface?

To Create a Surface Profile Along an Alignment

  1. Click Home tab Create Design panel Profile drop-down Create Surface Profile Find.
  2. In the Create Profile from Surface dialog box, in the Alignment list, select the horizontal alignment to use for the profile.

What is K value in Civil 3D?

K-Value. This value represents the horizontal distance along which a 1% change in grade occurs on the vertical curve. It expresses the abruptness of the grade change in a single value.

What is a design profile in Civil 3D?

A layout profile is a designed object that shows the proposed grade and elevations to be constructed. Profiles are displayed on an annotated grid called a profile view. Display an existing ground profile in a profile view. Open drawing Profile-1. dwg, which is located in the tutorials drawings folder.

What is the difference between a datum and a datum feature?

Datums and datum features. A datum feature is a part feature (or FOS), that contacts a datum during measurement. A datum is a theoretically exact plane (or axis or center-plane), from which dimensional measurement should be made.

How many datums can a part have?

A datum system comprising three datum planes that are perpendicular to each other is called a three-plane datum system. This enables the optimal surface to be used as a datum.

Can you combine corridors in Civil 3D?

You can only merge corridor regions that are consecutive and along the same baseline. AutoCAD Civil 3D prevents you from selecting regions that are not consecutive. You can merge two consecutive regions along the same baseline that have a gap between them; however, when you merge them, the gap will be filled.

How do you make a surface from a corridor Civil 3D?
