Using the vector dataset plug-in asset function, you can quickly set the style of 3D line data, so as to achieve the beautification of 3D line data sets.

1. Run the SuperMap Editor tool controls to create a new spherical/planar scene and add 3D point, line and polygon data in UDB/UDBX format.









2. After adding the data, run the current level.
3. Click Data Beautification -> Asset Settings -> Vector Dataset , select the corresponding 3D line layer in the Vector Dataset Plug-in Asset Settings panel, and select the appropriate associated field. Select Asset Loft for Asset Type.



4. In the asset library of Unreal Engine, select the corresponding object (static mesh body with material effect), right-click, select Copy Reference from the menu, and paste the copied path into the corresponding attribute box in the attribute table of the vector dataset plug-in asset setting panel.



5. Click OK to see that the material object has been applied in the scene.



6. Repeat steps 3-4 if you need to change the file path of the referenced material.
7. After setting, the association between attribute fields and Unreal Engine materials will be recorded in the Project/Content/SceneInfos/Level/SceneInfos.json file corresponding to the scene. The relevant labels are as follows:
• ResoureConditions: Records the attribute fields and attribute values of the vector dataset.
• ResourceName: Records the Unreal Engine material object associated with this attribute value object.
• Caption, DataSetAlias, etc. record the name, data type and other information of vector dataset.



Set the break line effect for the 3D line dataset as shown in the following figure.
