As soon as a construction step has been carried out in the Sketcher (for example, adding a line), the corresponding input fields are displayed in the Tool docking window (here with the current label Edit element ).

You can also manually select an element in the sketch history [Sketch history] or in the Sketcher at any time to call up the dialog and change parameters if necessary.

Clicking on the Discard changes button button, changes are not taken into account.

If the Automatically Apply Changes [Automatically apply changes] checkbox is selected any valid change is automatically saved (but can be can still be undone [ Delete last step or Undo ]).

If the checkbox is not selected, when changes are made under " Edit Element [Edit element]," an OK button appears, and the changes are not applied until the button is clicked.

Example: When you selected " Rectangle," you changed the base point [Base point] X from 0 to 10. If you now select another element in the history, for example, that change will be lost.

Tip With " Apply Changes Automatically [Automatically apply changes] " enabled , [Automatically apply changes] you can work more dynamically.
