Function: The dialog contains configuration options for working in the class diagram editor and in the statechart editor.

Call: Tools → Options menu, UML category

When the dialog is exited, the changed options will be applied to all currently open UML editors.

Tab: General

Grid
Grid space	Grid line spacing (in pixels). Default value: 10
Snap to grid	: Elements in the UML editors are aligned to the grid when the position is changed. This setting can also be changed by means of a command in the editor.
Display grid points	: The grid is visible in the editor as a point grid.
Note Element If the text to be displayed is longer than the defined size, then an ellipsis (`...`) are displayed. In these cases, the tooltip of the note element displays the full text.

Maximum lines	Number of lines which are displayed in the note element. Minimum value: 1 Maximum value: 100

Tab: Statechart

Position together condition and action of a relation	: A guard condition and an action that belong to the same transition are always repositioned together in the diagram.
Fixed size of states	: The size of states in the diagram are unchangeable.

Tab: Class Diagram

Show prompt when deleting objects from diagram	: The command for removing the selected elements from the diagram first displays a dialog prompt with the following options: Delete from diagram Delete from project and diagram (no undo possible)
Skip Refactoring Preview	: When refactoring is triggered in the diagram, the project-wide change is made without first opening the Refactoring dialog with a preview of all changes. You can see whether or not the preview is activated in the open class diagram editor at the KD: Refactoring Preview entry in the taskbar of the main window (green: activated; red: deactivated). For a description of the refactoring functionality, see the CODESYS help: CODESYS Development System > Programming of Applications > Refactoring.
Hiding variables
Hide internal variables	In the class diagram, all variables which have one of the following scopes are hidden in the POUs: `VAR`, `VAR_TEMP`, `VAR_STAT`, or `VAR_INST`
Hide signature variables	In the class diagram, all variables which have one of the following scopes are hidden in the POUs: `VAR_INPUT`, `VAR_OUTPUT`, `VAR_INOUT`, or `VAR_EXTERNAL`
Hiding POU members by access level The following options can be used to hide or show access modifiers for methods, actions, transitions, and properties. Members with an access modifier with a lower access level are shown or hidden. The priority of the access levels in descending order is as follows: `INTERNAL`, `PROTECTED`, `PRIVATE`
Hide PRIVATE members	: All POU members with the `PRIVATE` access modifier are hidden in the class diagram.
Hide PROTECTED members	: All POU members with the `PROTECTED` and `PRIVATE` access modifiers are hidden in the class diagram.
Hide INTERNAL members	: All POU members with the `INTERNAL`, `PROTECTED`, and `PRIVATE` access modifiers are hidden in the class diagram.
Hide all members	: All POU members are hidden in the class diagram.
