road engineering design

Instructions for use

The Road Engineering Design function can quickly construct models such as roads, bridges, and tunnels based on terrain tile and upload (TIN), 3D line dataset, and parameters information.

Function Entry

  • 3D Geodesign选项卡->Procedural Modeling组->Road Engineering Design按钮

Operation Steps

  1. Open the target datasource in the Workspace Manager, then load the 3D line data into the scene.
  2. Click 3D Geodesign选项卡的Procedural Modeling组中的Road Engineering Design, and the "Road Engineering Design" dialog box will pop up.
  3. Road Line Data Settings:
    • Data Source: Select the datasource where the source dataset is located via the drop-down button, defaulting to the first datasource in the current workspace.
    • Dataset: Select the 3D line dataset participating in the operation via the drop-down button.
  4. Pier Setting: Set the data paths for pier bottom, pier body, and pier top. These data are CSG models represented in JSON format, which can be constructed using the GPA tool in the Toolbox->3D Geodesign->Parametric Model group.
    • Pier Bottom (CSG): Set the path for the pier bottom model data by clicking the button on the right to select the target path in the "Open" dialog or directly inputting the absolute path in the dialog.
    • Pier Body (CSG): Set the path for the pier body model data by clicking the button on the right to select the target path in the "Open" dialog or directly inputting the absolute path in the dialog.
    • Pier Top (CSG): Set the path for the pier top model data by clicking the button on the right to select the target path in the "Open" dialog or directly inputting the absolute path in the dialog.
  5. Parameters
    • TIN Terrain: Set the file path for the terrain tile and upload (TIN) participating in the road design operation.
    • Road Width: Set the road width by directly entering a value or selecting a property field from the drop-down menu, in meters.
    • Road Thickness: Set the road thickness by directly entering a value or selecting a property field from the drop-down menu, in meters.
    • Slope Protection Angle: Set the slope protection angle by directly entering a value, in degrees. The slope protection angle refers to the angle between the slope protection surface and the horizontal plane.
    • Slope Protection Tolerance: Set the slope protection tolerance by directly entering a value, in meters.
    • Pier Spacing: Set the spacing between adjacent piers by directly entering a value, in meters.
    • Bridge Tolerance: Set the bridge tolerance by directly entering a value, in meters.When the height difference between the road centerline and the corresponding terrain is greater than the specified bridge tolerance, a bridge will be constructed.
    • Tunnel Height: Set the tunnel height by directly entering a value, in meters.When the height difference between the road centerline and the corresponding terrain is less than the specified tunnel tolerance value, a tunnel will be constructed.
    • Tunnel Tolerance: Set the tunnel tolerance by directly entering a value, in meters.When the absolute value of the height difference between the road edge line and the corresponding terrain exceeds the specified slope protection tolerance, slope protection will be constructed.
    • Tunnel Arch Height: Set the tunnel arch height by directly entering a value, in meters.
  6. Material Settings: Set the material color of the road via the drop-down color palette.
  7. Texture Settings: Set the texture map for the road.
    • Texture Source: Select a property field as the texture source via the drop-down menu. The relevant property field should record the absolute path of the texture.
    • Texture Path: When no property field records the texture source, specify the texture map via the selection button on the right of the texture path in the pop-up open dialog. Currently supports picture files in formats such as *.png, *.jpg, *.jpeg, *.bmp.
    • Repeat Mode: Used to set the repeat mode of the texture, including repeat times and real size.
      • Repeat Times: Refers to the number of times the texture is repeated, divided into horizontal repeat times and vertical repeat times.
      • Real Size: Refers to texturing according to the specified size, divided into horizontal size and vertical size.
    • Horizontal Repeat: Set the horizontal repeat size of the texture by directly entering a value or selecting a property field. When the repeat mode is repeat times, horizontal repeat refers to the number of times the texture is repeated horizontally, in times. When the repeat mode is real size, horizontal repeat refers to the real size of the texture horizontally, in meters.
    • Vertical Repeat: Set the vertical repeat size of the texture by directly entering a value or selecting a property field. When the repeat mode is repeat times, vertical repeat refers to the number of times the texture is repeated vertically, in times. When the repeat mode is real size, vertical repeat refers to the real size of the texture vertically, in meters.
  8. Result Data Settings:
    • Data Source: Set the datasource for storing all result data via the drop-down menu.
    • Slope Protection_Fill Side, Slope Protection_Cut Side, Tunnel, Pier, Road, Road Surface, Tunnel Convex Hull: Used to set the names of corresponding datasets.
  9. After setting all parameters, click Run to execute the road engineering design operation.
