Create a new schematisation
New schematisations can be created from the 3Di Models and Simulations panel.
Creating a new schematisation from scratch
To create an entirely new schematisation, go through the following steps:
- Open the 3Di Models and Simulations panel (  ). ).
- Choose a schematisation name (obligatory), fill in a project number (optional) and add tags (optional). 
- If you have rights to more than one organisation, choose the organisation that is to own the new schematisation. 
- In the GeoPackage section, choose the option Create new GeoPackage*. 
- Click Next. 
- Fill in other settings, such as the projection and friction type and simulation time step. 
- Click Create Schematisation. 
A Schematisation has now been created on the server. The corresponding folder in your local 3Di working directory contains the geopackage and (if chosen) a DEM and/or friction raster. This data itself has not been uploaded yet. See Uploading a schematisation for instructions to upload this data as a new Revision.
Copying an existing schematisation
The New schematisation wizard can also be used to copy existing schematisations. This is useful when for example, you have a schematisation of the “current situation” and you want to investigate one or more alternatives for “future situations”. In such a case, you can copy the current situation situation and start making changes in the copy, without affecting the original schematisation.
Go through the following steps:
- Make sure you have downloaded the schematisation revision you want to create a copy of. 
- Open the 3Di Models and Simulations panel (  ). ).
- Choose a schematisation name (obligatory), fill in a project number (optional) and add tags (optional). 
- If you have rights to more than one organisation, choose the organisation that is to own the new schematisation. 
- In the GeoPackage section, choose the option Choose file. 
- Browse to the location where the geopackage is stored that belongs to the schematisation you want to copy. This is usually “<3Di working directory><Schematisation name>work in progressschematisation<schematisation name>.gpkg” 
- Click Create Schematisation. 
A Schematisation has now been created on the server. The corresponding folder in your local 3Di working directory contains a copy of the geopackage and all the rasters it references. This data itself has not been uploaded yet. See Uploading a schematisation for instructions to upload this data as a new Revision.
