You can find this measurement function e.g., in the Measure menu, or as a button on the Measurement toolbar. In the Select Measurements dialog box, you can select additional measurement parameters for 2D objects, or delete parameters that don't interest you. See also Measuring a rectangle1.Load the image you want to measure into the document group. 2.Select the Rectangle measurement function. To do so, display, e.g, the Measurement toolbar. To do so, use the View > Toolbars > Measurement command.
