Deleting Objects

Press DEL to delete a selected object. The object will thus be deleted from the CadnaA main window and also from the object table. When another object of the same type exists, this will be automatically selected after deletion of the previous one so that this object can be deleted as well by pressing again the DEL key.

Delete (Context Menu)

The Delete command from the context menu (see Chapter 12 - Context Menu) has the same effect. Using this command also deletes just the selected object.

Action „Delete“ (dialog Modify Objects)

In order to delete a large number of objects of the same or of different object types select the action „Delete“ from the dialog Modify Objects (via the context menu of the CadnaA main window).

Undo

The command Edit|Undo or the key combination CTRL+Z enables to undo the following actions stepwise:

  • changes of an object’s geometry on the CadnaA main window, for example:
    • adding/deleting a polygon point
    • relocating an object
    • rotating/stretching of objects
  • editing of objects via their object dialog, for example:
    • changing numerical values or text
    • selecting an option from a list box
    • activating/deactivating a check-box
  • deletion of objects

Note

In order to retrieve a data row of an object table, first close the table and select the command Undo afterwards.

Undo (Modify Objects dialog)

The Undo command is also available for actions launched via the Modify Objects dialog.

The last action is listed on the Edit menu. The following strings are used:

  • Undo Geometry <Object Type>
  • Undo Edit <Object Type>
  • Undo Delete <Object Type>
  • Undo Action/Command

Further Remarks

  • The action "Undo" is applied stepwise in inverse direction of the input sequence of actions (for up to 256 steps).
  • When editing objects, closing the object dialog by OK will count as an action while closing the dialog via button "Cancel" will not.
