Extrude Closed Body

Instructions for use

The Extrude Closed Body function supports stretching Terrain Tiles (TINs) data up or down to a specified level to form a closed body, and outputting Result Data as Model Dataest. This function can build solid models for 3D printing.

Function entrance

  • 3D Geographic Design tab-> TIN Operation-> Extrude Closed Body

Operation steps

  1. Load Terrain Tiles (TIN) in the scene (Config File format is *.sct).
  2. Select the Terrain Tiles layer in Layer Manager, right-click "Jump to Layer", and hold down the mouse wheel in Scene to adjust the camera to a view that is easy to operate.
  3. In TIN Operation on the 3D Geographic Design tab, click the Extrude Closed Body button to pop up the Extrude Closed Body "panel.
  4. Layer selection: Click the drop-down arrow in the combo box on the right side of TIN Terrain to select the layer of the target TIN Terrain.
  5. Result Data Settings
    • Datasource: the first Datasource in the Current Workspace is selected by default, and the Datasource storing the Result Dataset can be selected through the drop-down list box.
    • Dataset Name: Enter a string as the name of the Result Dataset.
  6. Stretch Range Settings
    • Default: Without Range Settings, use the Default Range of TIN Terrain.
    • Custom Bounds: When the Custom Bounds "check box is selected, you can set the extrusion range, including selecting faces and drawing faces. Drawing faces can be scoped by Draw Rectangles, polygons, and importing external 2D/Region3D.
  7. Stretch Parameter Settings
    • Clip Mode: Includes Reserved Area and Outside the reserved area to determine whether the Extrude Closed Body is created inside or outside the extent face.
    • Clip boundary elevation: includes Keep with source data "and Keep with clip polygon". "Keep with source data" means that the extrusion result boundary elevation value is consistent with the original one and remains unchanged; "Keep with clip polygon" means that the extrusion result boundary elevation is consistent with the extrusion range face boundary elevation value.
    • Stretch to: Set the specified height value to which the data is stretched. It can be set by direct input or adjustment of the up and down arrows. The parameter value needs to be greater than maximum height value of the terrain or less than minimum height value of the terrain.
    • Level: enter the level parameter, and stretch only the data of the specified level after setting.
  8. After setting the above parameters, click the "OK" button to execute the TIN TerrainExtrude Closed Body operation. At the end of the operation, a Model Dataest named after the Dataset Name will be generated under the specified Result Datasource. The sample rendering is as follows:
Caution:
    An open Datasource must exist before
  • operating the Extrude Closed Body.
    • The result of
  • Extrude Closed Body is Save as Model Dataset.
