Creating a Platform Earthwork

You can create the geometrical design of a platform on terrain by modifying the initial terrain. You can create a platform cross section that is an input necessary for the platform creation.

  1. From the Civil Engineering section of the action bar, click Platform Earthwork .
  2. Select a surface or a closed curve (highlighted in blue in the 3D area).
  3. Select a polyhedral terrain.
  4. To select a platform cross section containing predefined excavation and filling profiles, do one of the following:
    1. Select a platform cross section in the Cross Section node in the tree when it is available in the same assembly. Or click Search an object type .

      Only object types corresponding to the chosen discipline (which can be a platform, a road, or a railway) and undefined object types are visible. The content provided in the SubgradeTypicalCrossSections.3dxml stored in the ...\startup\Civil\Alignment directory has been updated in R2022x GA to take the discipline into account.

    2. Select a platform cross section in the list.
    3. Optional: Sketch a new profile.
    4. To remove the cross section, click .
  5. Optional: To display a preview of the selected object type in a side panel, click Template Helper .
    A template viewer opens next to the Platform Earthwork dialog box and displays the shape of the object type and axis systems.

    In the Helper, you can move and zoom in the object type. Click again the same input and the object type moves back to its initial position.

    To close the Helper, click or Close or

  6. Optional: To modify the terrain and compute excavation or filling works, select the following options:
  7. To visualize the excavation and filling profiles on the terrain in the 3D area, click Preview.
  8. Click OK.
  9. Optional: To modify the terrain and compute excavation or filling works, select the following options if:
  10. Optional: To extrapolate the last section of the cross section profile to the terrain, select the Extrapolate cross section to terrain option. By default, this option is selected.
    • The cross section profile is systematically extrapolated to the terrain, as shown in the right figure below.
    • In some cases, you want to keep the profile as it is (as shown in the left figure below), without extrapolation.
    • This option allows you to have a choice about the profile extrapolation.
  11. Optional: From the Civil Engineering section of the action bar, click BIM Attributes and select the Excavation or Filling works in the tree to read the excavation and filling volumes (in the Bank volume box).
  12. To edit the cross section, select Platform Stretch Set in the tree and click under the Platform Cross Section area in the Platform Earthwork dialog box.
  13. To create a new cross section, you need to generate only one profile on the right side of the platform.
