Loading a schematisation

You can load a schematisation revision with the 3Di Schematisation Editor toolbar:

  1. Click on the ‘Open 3Di Geopackage’ or the ‘Load from Spatialite’ icon

  2. Select the schematisation you want to load from you local files

  3. Click on ‘Open’

You schematisation should now be loaded and you should be able to view all the elements in the Layers panel on the left.

Note

You might get the following message: “The selected spatialite cannot be used because its database schema version is out of date. Would you like to migrate your spatialite to the current schema version?”. Click ‘Yes’ and your schematisation should be loaded

Note

  • In the regular workflow, schematisation data is stored in a spatialite (.sqlite) . The Schematisation Editor stores this data in a geopackage (.gpkg). The database schema (the names and data types of tables and columns) of this geopackage also differs from the spatialite database schema. The Schematisation Editor loads the data from the spatialite into a geopackage; you make your edits in the geopackage, and when you have finished editing, save your changes to the spatialite.

Multiple styles per layer

For some schematisation layers, multiple predefined styles are available. These can be helpful to quickly visualise the needed information on the map.

To switch between stylings: 1) In the Layer panel, right-click the layer you are interested in. 2) Hold your mouse over Styles and the multiple styles will be shown. 3) Click the style you want to use. The style with the dot next to it is the active style.

Note: Some styles add a label to the object. Keep in mind when using these stylings that the labels only becomes visible when a certain zoom level is applied.

The default style depicts the locations of the objects in the layer. The other stylings are explained briefly below.
