3D models imported through this process can be either applied to existing [[Building]]s (replacing their generated 3D shapes by the more detailed 3D models), or new [[Building]]s can be generated which are visualized by the 3D models.
Imported 3D models can replace the generated shapes of existing [[Building]]s or be used to create new ones.

SLPK files defining 3D features can be imported so that the same 3D models can be visualized in the 3D Visualization of a Project. These models provide a higher level of visual detail and are integrated into the DSM, allowing for more accurate calculations for themes like water flow or shade.

Imported 3D models can replace the generated shapes of existing Buildings or be used to create new ones.

How to import an ArcGIS SLPK file:
  1. Open the Geo data wizard
  2. As Import type, choose either Buildings or Measures
  3. Choose as import method the I3S SLPK file option
  4. In the next step, either choose the height defined in the model (datum height) or place the models on top of the terrain.
  5. After selecting the file, continue to step 4
  6. In step 4, choose one of the following options:
    Create a new building using the uploaded model (a Function can be assigned in subsequent steps).
    Replace an existing building's model, or create a new building if none is present.
    Only replace the model of an existing building; Function and attributes are preserved, updating only the geometry. You may then finish the wizard.
  7. If you have chosen to create a new building, choose a name, function and stakeholders and then finish the wizard.
  8. Depending on the type you have chosen at the start of the Geo Data Wizard, the building is directly placed in the Tygron Platform project or a new Measure is created.

Notes

  • It is no longer required to Geo-position the SLPK. A button named 'Reposition Model' has been added to the Model Placement step of the Geo Import Wizard that allows you to reposition the 3D models in the project area.
  • When the SLPK model contains no textures, the 3D model will be plain white
  • Currently, Wrap mode: repeat is not supported in atlas textures
  • Only textures in JPEG format are supported
