How You Can Work with the Shape Layer
When a form includes shapes—such as lines, ellipses, or rectangles—OpenROAD Workbench separates the fields into two layers:
Bottom layer
Contains the shapes, which always stay underneath the other fields
Top layer
Contains the active fields and the trim fields, which always stay above the shapes
The Bring to Front and Send to Back commands on the Layout menu work only within a layer. Therefore, you cannot use these commands to move a scalar field or trim field underneath a shape. If you cannot select a shape because it is completely covered by a scalar or trim field, you must drag the field off the shape.
Note: You can also use the Frame Editor's Field Tree feature. Locate the field in the Field Tree window and click it. The selected field is then highlighted in the Frame Editor. For more information, see Use the Field Tree.
