Hiding an Annotation Layer
By separating shapes into layers, you can show or hide particular kinds of shapes by showing or hiding the layer that own the shapes, which helps in delivering works to different types of users. With this example, you can export diagrams without annotations, and send user the result, while the internal copy can have the annotation existing. To hide a layer:
- Open the Diagram Layers window again.
Uncheck the checkout in Visible column for the Annotation layer.
You will find the callout hidden in diagram.
