The Tygron Engine can be used for importing spatial plans in the Engine to evaluate certain design measures in a plan, for example if the parking standard is feasible. Depending on the use case of importing the spatial plan, there are some things to be taken into account:
In principle every spatial plan can be imported, as long as the original format of the drawing can be converted to any of the supported file formats. Take into account that the level of detail in the {{software}} does not include interior designs.
* If the purpose is to create a 3D model of a 2D- drawing, remember that the level of detail in the Engine is not so high. Therefore, if the plan is very detailed, the design might not be distinguishable in the Engine.
* If the purpose is creating a visualization of the plan, sometimes it may be better to use placeholders for buildings, to emphasize the design phase in the project.
 
Most of the spatial plans on a smaller scale are being drawn in AutoCAD (AutoCAD Map 3D, AutoCAD Architecture). Therefore, below are some steps provided to import a plan as an AutoCAD file to a [[GeoJSON]] for importing in the Engine.
In principle every spatial plan can be imported, as long as the original format can be converted to a [[GeoJSON]].


==How to insert a spatial plan to the Engine==
There are some requirements on a the spatial plan before importing it into the {{software}}.
The first step is to convert the AutoCAD drawing to polygons and saving this file as a Shapefile (.shp). This can be done in AutoCAD Map, if you have another AutoCAD or if this is not possible, save the Autocad drawing in AutoCAD instead as a .dxf file.
* Geometries: Features from a spatial plan are required to have a geometry to define its spatial shape and location.
* Coordinate system: Choose a coordinate reference system for your drawing and draw and scale the plan on the right location on the planet. The most used coordinate system in the Netherlands is Amersfoort/RD New (EPSG:28992). Without a correct location, the drawing could be anywhere on the planet and not possible to import in any spatial software on the right location.
* Layer naming: Features can be grouped together in layers. For example: offices are drawn in the layer offices, while student houses are drawn in the layer student houses. The layer name can be used for classification.
* Attributes: Attributes can also be assigned to Features, optionally with a specific value. These can be used for classification.

Now the .dxf or .shp file can be opened in a GIS (Geographical Information System). In this example QGIS is used. The .dxf/.shp file can be opened by dragging the file in QGIS.
When you want a spatial plan to be implemented in your project, you basically have two options:
QGIS prompt to choose a Coordinate Reference System (CRS). Choose the coordinate system that is being used for the spatial plan. In the Netherlands, this is probably always Amersfoort/RD New (EPSG:28992).
* Import the spatial plan directly into the current state of your project. You will be able to perform calculations for this project, but will not be able to revert back to the previous situation unless you revert back to a previously saved [[Project Version]].

* Place the spatial plan in one or more measures. When placing it in multiple measures you must make sure the measures are not overlapping spatially, because that will prevent you from activating the measures all at once.
If you have a .dxf file, QGIS asks which layers you want to open. Choose Select All en click Ok.
There are then four layers added to QGIS:
* a Point layer, which consists of the text elements
* a LineString layer which holds all the layers of the AutoCAD file
* a Polygon layer, which contains the hatches of the AutoCAD file
* a GeometryCollection layer, which contains the references for symbols used in the Engine?

A spatial plan is a design of an area with focus on the landscape, environment, routing, the interaction between public and private space, buildings forms, materialization and more. This design can be made for an urban area as part of an urban planning project or for a more rural area for a landscape design or land art project. Spatial plans are created by urban designers or landscape architects and can have different scales and therefore different level of detail.

The Tygron Platform can be used for importing spatial plans to evaluate certain design measures in a plan, for example if the parking standard is feasible.

Requirements on a spatial plan

In principle every spatial plan can be imported, as long as the original format of the drawing can be converted to any of the supported file formats. Take into account that the level of detail in the Tygron Platform does not include interior designs.

There are some requirements on a the spatial plan before importing it into the Tygron Platform.

  • Geometries: Features from a spatial plan are required to have a geometry to define its spatial shape and location.
  • Coordinate system: Choose a coordinate reference system for your drawing and draw and scale the plan on the right location on the planet. The most used coordinate system in the Netherlands is Amersfoort/RD New (EPSG:28992). Without a correct location, the drawing could be anywhere on the planet and not possible to import in any spatial software on the right location.
  • Layer naming: Features can be grouped together in layers. For example: offices are drawn in the layer offices, while student houses are drawn in the layer student houses. The layer name can be used for classification.
  • Attributes: Attributes can also be assigned to Features, optionally with a specific value. These can be used for classification.

How to import a spatial plan

When you want a spatial plan to be implemented in your project, you basically have two options:

  • Import the spatial plan directly into the current state of your project. You will be able to perform calculations for this project, but will not be able to revert back to the previous situation unless you revert back to a previously saved Project Version.
  • Place the spatial plan in one or more measures. When placing it in multiple measures you must make sure the measures are not overlapping spatially, because that will prevent you from activating the measures all at once.
