How to create an SLPK file

This page provides information on how to export a SLPK file with ArcGIS Pro. The ArcGIS PRo version used in this documentation is 2.4.0.
To learn more about ArcGIS Pro visit ESRI's ArcGis Pro Documentation. In order to export a 3D model as a SLPK, it has to be imported into ArcGIS Pro and Georeferenced to place the model on the right location. ArcGIS Pro allows different file formats to be imported. There are differences in for example how a DWG file is added to your ArcGIS Pro project from other 3D file formats. Both will be explained below.
In general for the 3D models, make sure there are no duplicate polygons in the 3D model.

1. Creating a new ArcGIS Pro project

To add a 3D model like CAD or OBJ you should first create a new project in ArcGIS Pro. When starting a new project make sure that you select a local Scene from the Blank Templates section. You can convert a local scene to a global scene after you have imported your model(s).

2. Adding 3D data files

Adding a DWG file

If you are working with CAD data, see the steps on How to import a DWG file.

Import a SketchUp model

To import a SketchUp model, see the How to import a SketchUp model in ArcGIS Pro.

Importing other 3D file formats

To import other 3D files like OBJ, DAE, 3DS, FLT or WRL, see the How to import a 3D file.

2.b Importing and assigning texture maps on an imported model

If your model has a texture map and it is not loaded onto the model after importing you can import it manually in ArcGis Pro. To import and assign a texture follow the steps in the How to import and assign textures.

3.Georeference your imported model

If the 3D model is not yet on the right location on the map, follow the steps in the How to to georeference the model: How to Georeference a 3D model.

4. Export the model as a SLPK file

After importing and if needed Georeferencing your model(s) you can export them to a SLPK file by following the steps below, which are divided into three sections. Please follow them in order.

  Conversion tool

  Input feature

  Output Feature Class

How to create a Feature Class:

1. In ArcGIS Pro go to the "Analysis" Tab and select "Tools".
2. On the right pane navigate to the "Feature Class to Feature Class" tool or type it in the search bar to find it.
3. In the "Input Features" field select the Multipatch feature of the imported object by clicking on the dropdown in the field to select it. Make sure it is the Multipatch version and not the original object
4. The Output location will be a .gdb (database file) with the project as a name. Leave the default name as is or rename it if you prefer.
5. In the "Output Feature Class" field type in a name.
6. This will save the Multipatch to the database.
7. Click on "Run" at the bottom right of the pane.

How to create a Layer 3D:

1. Go to the "Analysis" Tab and select "Tools" again.
2. On the right pane navigate to the "Layer 3D to Feature Class" tool or type it in the search bar to find it.
3. In the "Input Feature Layer" field select the newly created feature class not the original multipatch.
4. An automatic name will be generated in the "Output Feature Class" field. Usually it will append a "_Layer3DToF1" tag after the Multipatch name. Leave as default or rename it if you want. Make sure that you can identify the name because we will be needing it in the final step.
5. Check "Disable Color and Texture" only if you do not want these features to be converted.
6. Click on "Run" at the bottom right of the pane.

How to Export to SLPK:

1. Finally go to the "Analysis" Tab and select "Tools" again.
2. On the right pane navigate to the "Create 3D Object Scene Layer Package" tool or type it in the search bar to find it.
3. In the "Input Dataset" field select the created Layer3d file from the previous steps.
4. In the "Output Scene Layer Package" field type in the name for the SLPK file wich will be created and choose the location for the file to be saved.
5. In the "Output Coordinate System" dropdown field select this projects system or select a new one by clicking on the grid sphere icon on the right of the field.
6. Optimize the textures for various platform by choosing an option from the "Texture Optimization" dropdown field or leave at the default setting.
7. Click on "Run" at the bottom right of the pane.
8. Now a SLPK file will be created.

Importing a SLPK into the Tygron Platform

After creating a SLPK file, the data can be imported into the Tygron Platform by making use of the Geo data wizard. Read here for the steps on how to use the wizard.
