Selection methods—ArcGIS CityEngine Resources

You can use different methods of selecting objects when working with CityEngine scenes.

Select in the Viewport window

You can select objects in the Viewport window using the selection tools as well as the navigation, transform, and edit streets and curves tools.

These tools include the following methods to select objects:


Click	Selects an individual object. On an already selected object, components are selected (faces, edges, or vertices).
Double-click	Selects and frames an individual object.
Left-to-right selection rectangle	Selects objects or components that are fully inside the selection rectangle. Map layers are not added to the selection.
Right-to-left selection rectangle	Selects objects that intersect with the selection rectangle. Map layers are not added to the selection.*

* This option isn't available with the Lasso Selection tool.

The selection methods can be combined with modifiers:


Shift+click	Add to existing selection.
Ctrl+click	Deselects a selected object or adds an unselected object to a selection.
Ctrl+Shift+click	Remove objects from an existing selection. Unselected objects are not added to the selection. This feature is especially useful when selecting using a selection box.

Right-click in the Viewport window to provide a subset of selection methods that are described in the Select main menu.

The following options are available to make selections in the Scene Editor window :


Click	On a layer/group layer: selects the layer, but does not select the scene objects inside. On a scene object: selects an individual object, deselects already selected objects.
Double-click	On a layer/group layer: has no effect. On a scene object: select and frame an individual object.
Shift+click	Add to selection, in lists: add adjacent objects.
Ctrl+click	Deselects a selected object or adds an unselected object to the selection.

The Select main menu provides methods to grow a current selection you made in the Scene Editor window or in the Viewport window .


Select All, Deselect All, Invert Selection	In this case, "All" means scene objects that are not locked and with visibility = true. Map layers are not included. Select all and deselect all can also be triggered using the shortcuts Ctrl+A and Ctrl+Shift+A. Invert the selection of all selected objects.
Select Objects in Same Layer	All objects in the same layer or layers are selected.
Select Objects by Map Layer	See Selection with image maps for details.
Select Objects in Same Layer Group	All objects in the same layer group or groups are selected.
Select Objects of Same Type	Selects all objects with the same type or types as the current selection.
Select Objects of Same Group	Selects all objects belonging to the same group as the objects in the source selection. For example, if the source selection contains a block, the resulting selection will contain the block and the block's shapes.
Select Objects with Same Rule File	Selects all objects having assigned a rule file that is present in the source selection.
Select Objects with Same Start Rule	Selects all objects having a start rule that is present in the source selection.
Select Continuous Graph Objects	This method can be used to select graph segments that are continuous, for example, if they together define one street. The search for continued segments starts at the source selection.
