What is an Attribute?

An attribute is a characteristic of a particular component in the 3D world like an area or a construction. An attribute is always a number and can have a positive or a negative value.

Attributes in relation to the Tygron Engine

Attributes contain information about a particular component which can be used in Excel calculations. The value of an attributed can be changed as a result of an Excel calculation or as the result of an event. Some of the attributes and their value at the start of the project are added by default. It is also possible to add or adjust attributes and the value manually. In addition, there is also the possibility to import attributes as part of importing GeoJSON files. The Engine's components which have attributes are: neighborhoods, areas, constructions and zones.

An attribute always consists of a name and a value. The value must always be a number. It can be either a positive or a negative number. When an attribute does not exist, its value is deemed to be 0. Note that this means that an attribute value of 0 can mean that the proper value of the attribute is 0, or that the attribute does not exist.

When you want to make use of an attribute in an Excel indicator you need to specify in the spreadsheet if the attribute is included int the calculation or not. This is done by the ACTIVE attribute. For the ACTIVE attribute the input is always 1 for active and 0 for not active.

How to add and remove attributes

Attributes can be added for neighborhoods, areas, constructions and zones. In order to add an attribute for one of these Engine components you need to first open the panel of the particular component. Per component the variety of (default) attributes can differ. Only the attributes that are relevant for the particular component are given. Based on the same principle the

This panel allows you to add new attributes
To add new attributes, open the Attributes tab on the right in the selected Engine component.

This panel allows you to select the attribute that you want to import
To select the attributes you want to import with a GeoJSON file, choose the right attribute name.
It is not possible to remove a single attribute. You can only remove all attributes at once.


How to add a new attribute:
  1. Enter a new attribute name
  2. Enter a value
  3. Select "Save New Attribute".
How to add attributes with a GeoJSON file:
  1. Option 1) Select the GeoJSON file in the folder Option 2)
    Hoover over the desired component in the Editor and Select import GeoJSON file
  2. In of case option 1 Drag and Drop the file in the Tygron Engine
  3. Select the desired input
  4. Make sure the attribute checkbox is checked
  5. Select the right attribute name
  6. Select the right attributes to import
  7. Select Send to import the attributes together with the imported area.
How to remove an attribute:
  1. To remove all attributes at once select "Reset Variables".


Edit attributes

In most cases it is not necessary to adjust the values of attributes. The values generally are coming from a database or are retrieved by default from the Tygron Engine. Changes in the values are normally made as a result of Excel calculations or an event.

Active (by default)

When an attribute is active it will be taken into account when it is used in an Excel calculation. The input is always 1 for active and 0 for not active. When the attribute is not active the attribute is present in the project but is not included in the calculation of all attributes

Color (by default)

Explanation is needed.

Add new Attribute with Name

This is the name of the attribute. This name will be used in the query language and can not be adjusted after selecting Save New Attribute.

Add new Attribute with Value

This is the value of the new added attribute at the start of the project. This value can be adjusted after selecting save New Attribute.

Reset variables

When selecting this function all attributes are removed from the right attribute tab.
