Creating a Section Viewport

Section views are placed in special viewports, called section viewports, on sheet layers. A section viewport can be created from either a design layer or a viewport on a sheet layer.

To create a section viewport:

1.

If creating a section view from an active design layer, set the layer to Top/Plan view by selecting View > Standard Views > Top/Plan. If creating a section view from an existing viewport, select a non-sectioned viewport object. The viewport object must be in Top, Bottom, Left, Right, Front, or Back view orientation.

2.	Select View > Create Section Viewport.

3.	Draw the section line to create the cutting plane on the design layer or viewport.

Click in the drawing and drag the mouse to begin drawing the section line. Click to mark the end of the section line, and then click to indicate the side of the section line to keep, which is indicated by a black arrow. Double-click to end the section line.

To create a broken section line, click in the drawing and draw the first segment. Indicate the section side to keep. Click and drag to draw additional segments; broken section line segments are always parallel or perpendicular to each other. Double-click to end the broken section line.

4.	The Create Section Viewport dialog box opens, set to the parameters of the active design layer or non-sectioned viewport.

Because a section viewport is a type of viewport created on a sheet layer, many of the parameters are identical to those required when creating a regular viewport as described in Creating a Sheet Layer Viewport from a Design Layer. Only the parameters necessary for creating section viewports are described here.

The view of a section viewport cannot be changed. In addition, wireframe and sketch rendering modes are not available for section viewports. (Hidden line rendering results can be sketched.)

 

Parameter	Description
Display Objects Beyond Section Plane	When selected, shows objects beyond the section plane, on the indicated side of the section; deselect to show only the objects that intersect the section line
Advanced Section Properties	Specifies advanced section viewport parameters defining the extent and attributes of the section view; see Advanced Section Viewport Properties

5.	Click OK. A section line object is created in the design layer, or is added to the annotation of the existing non-sectioned viewport. A section viewport is created on the selected sheet layer, and the drawing switches to that sheet layer, displaying the new section viewport.

By default, the cross-section areas (along the plane where the section was cut) are displayed in red.

A section viewport created from a design layer can be updated when changes are made to the design layer. However, a section viewport created from a viewport does not maintain a connection to the viewport that created it. It updates when the design layers that are visible in the source viewport change.
