Oblique Photography Model burrow

Instructions for use

The Oblique Photography Model is used to dig a hole in the area of the Oblique Photography Model. You can select a face or draw a face as the digging area.

Function entrance

  • 3D Geographic Design tab-> OSGB Data operation-> Dig hole button
  • Toolbox -> 3D Data -> Oblique Data Computation -> Oblique data digging

Operation steps

  1. Create Spherical Scene。 Right-click the Scene in Workspace Manager and select Create Spherical Scene ".
  2. Load OSGB/OSGB Cache. In Layer Manager, select the Normal Layer ", right-click the Add 3D Cache Layer..", or on the Scene tab, in the Data group, click the Cache Drop-down Button. Select Load Cache.. from the drop-down menu that pops up. For detailed operations, see Help "Load 3D Tiles .
  3. Select the OSGB/OSGB Cache file layer in Layer Manager, right click and select "Jump to Layer", and press and hold the mouse wheel in Scene to adjust the camera to the angle of view convenient for digging the hole model.
  4. On the 3D Geographic Design tab, in the Oblique Photography Operations group, click the Dig Hole button to display the Oblique Photography Model Dig Hole panel. Specific Parameter Settings are as follows:
    • Layer selection: Click the drop-down arrow in the combo box to the right of Oblique Layer, and select Dig Layer of Object.
    • Hole face determination: In the hole face group, there are two hole face determination methods: Select Face and Draw Face.
      • When you click Select Face, you select the face object in the scene to complete the determination of the hole face.
      • When you click Draw Face, use Rectangle, Polygon, and Import in the toolbar to determine the face of the hole.
      • Click the "Rectangle" or "Polygon" tool. After the top of the mouse is attached with a red dot, you can click the left button in the scene to start drawing the clipping area, and click the right button to finish drawing to complete the determination of the digging surface.
      • Click the Import tool to pop up the Import dialog box. Select Region Dataset or Model Dataest as the digging area, as shown in the following figure.

    • Export Hollow Region: supports exporting the drawn hole-digging surface by clicking the Export button.
    • Parameter Settings：
      • Click the drop-down arrow in the combo box to the right of the Clip boundary elevation ", and select one of the constraint methods in the Keep with source data" or Keep with clip polygon ". "Keep with source data" indicates that the boundary elevation value of the hole digging result is consistent with the original one and remains unchanged. "Keep with clip polygon" indicates that the boundary elevation value of the hole digging result is consistent with the boundary elevation value of the clip surface.
        • The Preview check box is available
      • only when the constraint boundary is Source Data Consistent. When the "Preview" check box is checked, the digging result can be previewed in real time.
  5. Click OK to dig the hole, or click Undo to undo the operation.
Caution:
  • When sketching a burrowed area, it is recommended to look down on the scene to ensure the accuracy of the sketched points.
  • When the Clip boundary elevation is set to Keep with source data ", the Z value of the excavation face has no effect.
  • The Oblique Photography hole digging operation is also applicable to the model cache, and supports viewing/rolling back the History after the model cache is operated.
