Road Engineering Design

Instructions for use

The Road Engineering Design feature quickly builds models of roads, bridges, tunnels, and more based on Terrain Tiles (TIN), 3D Line Dataset, and Parameters information.

Function entrance

  • 3D Geographic Design tab-> Rule-based Modeling group-> Road Engineering Design button

Operation steps

  1. Open Target Datasource in Workspace Manager and load 3D line data into the scene.
  2. On the 3D Geographic Design tab, click Road Engineering Design in the Rule-based Modeling group to bring up the Road Engineering Design "dialog.
  3. Road Line Data Settings:
    • Datasource: Select the Datasource where the Source Dataset is located through the Drop-down Button. The default is the first Datasource in the Current Workspace.
    • Dataset: Select the 3D Line Dataset participating in the operation through the Drop-down Button.
  4. Pier Setting: Set the data path of pier bottom, pier body and pier top. These data are CSG models in JSON format, which can be constructed by GPA tools in the Toolbox-> 3D Geographic Design-> Parametric Model group.
    • Pier Bottom (CSG): Set the path of Model Data at the bottom of the pier. Select Target Path in the "Open" dialog box by clicking the button on the right or directly Input Data: Absolute Path in the dialog box.
    • Pier body (CSG): Set the path of the Model Data of the pier body. Select the Target Path in the "Open" dialog box by clicking the button on the right or directly Input Data: Absolute Path in the dialog box.
    • Pier Top (CSG): Set the path of Model Data at the top of the pier. Select Target Path in the "Open" dialog box by clicking the button on the right or directly Input Data: Absolute Path in the dialog box.
  5. Parameter Settings
    • TIN Terrain: Sets the Terrain Tiles (TIN) File Path that participates in the Road Design operation.
    • Road Width: Set the Road Width in meters by entering the value directly or by selecting the Property Field in the drop-down menu.
    • Road Thickness: Set the road thickness in meters by entering a value directly or by selecting Property Field from the drop-down menu.
    • Revetment angle: Set the revetment angle in degrees by directly entering the value. 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 inputting the value, and the unit is meter.
    • Pier spacing: set the size of the spacing between adjacent piers by directly entering the value, in meters.
    • Bridge Tolerance: Set the bridge tolerance size in meters by entering the value directly.
    • Tunnel Height: Set the tunnel height in meters by directly entering the value.
    • Tunnel Tolerance: Set the size of the tunnel tolerance in meters by entering the value directly.
    • Tunnel Rise: Set the tunnel rise size in meters by entering the value directly.
  6. Material Settings: Set the material color of the road from the drop-down color palette.
  7. Texture settings: sets the road Texture Map.
    • Map Source: Select Property Field as the map source through the drop-down menu. The absolute path of the map should be recorded in the relevant Property Field.
    • Texture Path: When there is no Property Field that records the source of the map, specify the Texture Map in the pop-up Open dialog box by selecting the button on the right side of the texture path. Picture File in formats such as *.png, *.jpg, *.jpeg, and *.bmp is currently supported.
    • Repeat Mode: Lets you set the repeat mode for the map, including Repeat Times and Real Size.
      • Repeat Times: refers to the number of times the map is repeatedly placed, which is divided into horizontal Repeat Times and vertical Repeat Times.
      • Real Size: refers to the mapping according to the specified size, which is divided into horizontal size and vertical size.
    • Horizontal Repeat: Set the size of the horizontal repeat display of the map by directly entering a numeric value or selecting the Property Field. When the repeat mode is Repeat Times, the horizontal repeat is the number of times the map is repeated in the horizontal direction, in units. When the repeat mode is Real Size, the horizontal repeat refers to the Real Size of the map in the horizontal direction, in meters.
    • Vertical Repeat: Set the size of the vertical repeat display of the map by directly entering a numeric value or selecting the Property Field. When Repeat Mode is Repeat Times, Vertical Repeat is the number of times the map is repeated vertically, in units. When the repeat mode is Real Size, Vertical Repeat refers to the Real Size of the map in the vertical direction, in meters.
  8. Result Data Settings：
    • Datasource: Use the drop-down menu to set the Datasource for all Result Data stores.
    • Revetment _ Fill, Revetment _ Excavation, Tunnel, Pier, Road, Road Surface, Tunnel Convex Hull: used to set the name of the corresponding Dataset.
  9. When all parameters have been set, click Run to execute the Road Engineering Design operation.
