Horizontal Alignment

Horizontal Alignment

Horizontal Alignment

1. Open a New Project in your CivilCAD software.
2. Creat a surface. Import Topography and Breaklines. Use the Surfaces chapter instructions: How to Create a Surface (Contours) - CivilCAD User Manual.
3. Ensure breaklines are correctly assigned to maintain surface accuracy. Verify the surface is generated and visible in the model space.
4. Check roads list. Use roads list chapter instructions: Road List - CivilCAD User Manual
5. Define Horizontal Alignment:

• Go to Roads → Horizontal Alignment. This will open a window on your right.
• Click the arrow on the right to select a road.

• Choose a road from the list.
• In order to define the centerline of the road, use one of the following options:
  • Unused: Not for use at this time.
  • Locate: Choose points that exist in the databas.
  • Pick: Draw a new centerline by clicking “freely” on the screen. Each stop generates a new IP. Choosing points “freely”, means that wherever you position your cursor, is where the point is chosen.
  • Select: In AutoCAD/ZWCAD, draw a Polyline (2D Polyline) that will serve as the Horizontal Alignment of the center line. Choose ‘Select’ from the table on the right. In the AutoCAD/ZWCAD command line, press 'Enter' for <Polyline>. Move to the drawing area and choose the drawn Polyline and click ‘Enter’.

Finalize the Centerline:

1. After drawing or selecting press Apply.
2. A window will apear on the drawing with options:

• Choose which parameters you want to see on the road. Press  OK.

Post-Alignment Updates

1. DWG View:

• Centerline turns red.
• Flags appear at curves/junctions.
• Sections are shown at defined intervals.

1. Right Panel Table:

• Lists IP (Intersection Points).

1. Bottom Coordinates Table:

• Displays newly added points.

1. Once the road have been added to your project, you can enter additional details for each road in the table, such as the radius of the turns and other relevant parameters.

Options Table

1. Use this table to control:

• Sections view (outside or inside).
• Format of sections.
• Various options for the graphical representation of the road in planning.
• Define sections.
• Etc.

Define sections

1. Press Define sections button.

1. Use this table to control:

• Sections format.
• Destance between sections
• Etc.

Horizontal Alignment buttons and options

1. Read center line from file: Will copy the data from *.dis or *.xml files.
2. Save to LandXML: Save your data to *.xml files.
3. Erase corrent IP: Stand on a line at the table and press to erase a single line.
4. Clear all IP’s: Will erase all lines of the IP’s
   table.
5. Reorder All Roads: This option is very useful when working on a project that includes multiple roads, especially when the numbering of the roads or their IP addresses is not sequential. For example, if a road was deleted from the project and later new roads were added, the IP prefixes may no longer follow a consistent order between the roads. To maintain proper order within the project, you can use this option. Once you press the button, a window with additional options will appear.
6. Options: Open the options table.
7. Reverse Current Road: Reverse the order of the IP's in the coordinates list — the first IP will become the last, and vice versa. Once the IP's are reordered, the program will generate the road layout in the opposite direction. To apply the changes, click 'Apply' and then 'OK'.
8. Pick station: Add new station points to the road.
9. Change alignment: Change the road's centerline.
