Editing Objects

After having entered an object graphically with its coordinates the necessary object data (e.g. number of cars per day or hour on a road, speed, road surface or just the emission value) must be edited. This is usually achieved via the object’s edit-dialog using the keyboard. However, object data may also be imported using the various import filter in CadnaA (e.g. the ODBC interface, see Database Import (ODBC & XLSX) in the CadnaA reference manual or chapter ODBC-Import in this manual).

To this end, to edit or to delete a object, first switch to the Edit Mode by either clicking the pertinent icon or pressing the hotkey CTRL+E. Then, in the graphic representation, you can choose among three different methods to open the dialog:

  • within input mode enabled (see Insert Objects): Click with the right mouse button once on the object, either onto its border (e.g. area source, buildings) or onto its centre line (e.g. road, railway).
  • within edit mode enabled (CTRL+E):
    • double-click the borderline of the object or onto its centre line (with roads or railways), or
    • locate the mouse pointer onto the border of the respective object. Clicking with the right mouse button opens the context menu. Select the command Edit using the left mouse button or press the RETURN-key while the object is selected.

Undo

Changes of an object’s geometry on the CadnaA main window or editing parameters of objects via their object dialog, can be undone (see Deleting Objects).

Editing an Object Table

Data sets can also be edited via the respective object table.
