Addressing Actions to a Group of Objects
Objects can be grouped to apply any command only to the objects in the group. This grouping is possible by selecting the object types, by drawing a closed polygon (fence) or by defining the activation of the objects included (switched on or off), and all these selection possibilities can be used in combination.
Furthermore, a conditional expression can be entered for operations with all kinds of objects. For editing such a conditional expression all attributes of the selected object type are available. With an object type being selected, an atribute is selectable from the pull-down list. This new feature allows to edit complex expressions. The operation will be executed only if the condition is fulfilled (expression <> 0).
Conditional expression to address the building evalution symbol to buildings ...
- ... with a height > 3 m and an area > 50 sqm. The red colored buildings have been excluded.
