Creating a Design Layer Viewport by Cropping

These steps require that the viewport and the design layer that displays in it are in the same file.

To create a design layer viewport by cropping:

1.	Access the design layer that will display in the viewport.

2.

Create a 2D object (such as a rectangle, oval, circle, polyline, or polygon). The 2D object must define an area; for example, a 2D line cannot be used. Position the 2D object on the design layer to delimit the area to be included in the new viewport. The fill of a viewport crop object is always None; however, the pen style can be set from the Attributes palette.

3.	Select the 2D crop object, and then select View > Create Viewport.

4.	An alert dialog box asks whether the object should be used as the viewport’s crop. Select Yes (also select Always do the selected action to always use a selected 2D object as a crop object when creating viewports).

5.

The Create Viewport dialog box opens. Select the design layer on which to create the viewport. The Source must be the current document. Specify the design layers and classes to display in the viewport. (See Changing the Layer Properties of Design Layer Viewports and Changing the Class Properties of Design Layer Viewports.)

6.

Click OK.

The viewport, cropped by the selected 2D object, is created on the specified design layer.

To hide the crop object, edit the viewport’s crop (see Cropping Design Layer Viewports) and set the object’s Pen Style to None. Alternatively, change the class of the crop object to invisible.
