Provides access to members that control undo/redo capabilities for edit sketch modifications.
Use sketch operations to provide undo and redo capabilities when making modifications to the edit sketch. For example, if you wanted to insert a new point in the middle of the edit sketch, create a sketch operation so the edit can be undone.
ISketchOperation derives from IOperation giving these additional methods: CanRedo, CanUndo, Do, Redo, Undo.

| SketchOperation | Provides undo/redo capabilities for edit sketch modifications. |
Sketch operations are very similar to Editor operations. First, call Start to flag the beginning of the Sketch operation. Use the MenuString property to give the operation a name. Perform the edits. Call Finish to complete the edit operation. Finish requires an envelope parameter that is used to invalidate/refresh the display.
The follwing code can be used in the ICommand::OnClick method before the sketch operation.
The editor was declared as a class field and set in the OnCreate method.
...
m_editor.StartOperation();
ISketchOperation sketchOperation = new SketchOperationClass();
sketchOperation.MenuString_2 = "specificSketchOperation";
sketchOperation.Start(m_editor);
//do sketchOperation...
