OpenCities Planner comes with a 3D-library with simple volumes and generic models. You can use them for sketching or adding to an uploaded 3D-model.
The simple volumes are:
- Tall cuboid
- Long cuboid
- Roof structures
Once added to the 3D-world, you can set the same properties as uploaded 3D-models.
Dimensions can be edited by stretching the volume with the object tool or in the text fields in meters to set a specific dimension. You can set the color and opacity of the volume in the sub page Attributes.
