To Create a 2D or 3D Section

Use this procedure to create a 2D or 3D section. After you draw a section line, you extract a section from the section line and the objects you select in the building model.

Tip: Before you create a section, thaw and turn on all layers containing objects that you want to include in the section. Objects on layers that are off or frozen cannot be part of the selection set for the section. To enhance performance, turn off the layers of the objects that you do not need to include in the section.

Caution: If you want to insert a 2D section in a Plan view, make sure that the display set used for the Plan view does not section objects by display range. In that case, the section result would not be displayed in the Plan view. To make sure that this is not the case, click Manage tabStyle & Display panelDisplay Manager. Select the Plan display set for the currently used display configuration. On the Display Options tab, verify that Section AEC Objects by Display Range defined in Display Configuration is cleared.

1. Draw a section line in the drawing.
2. Select the section line, and click Building Section Line tabModify panelGenerate Section.
3. Select the type of section object you want to create:

   If you want to create…	Then…
   a 2D section	select 2D Section/Elevation Object with Hidden Line Removal.
   a 3D section	select 3D Section/Elevation Object.

4. For Style to Generate, select a style for a 2D section.

   If you want to use a particular style, select it from Style to Generate. Otherwise, use the Standard style.

   3D sections do not use styles.

5. Under Selection Set, click (Select Objects), and select the objects that you want to include in the section. Press Enter when you finish selecting objects.
   Note: If you select an object that you do not want to include in the section, hold down Shift and select the object again to remove it from the selection set.
6. Under Display Set, select a display set for the section object.

   The display set controls the representation of the section.

7. Under Placement, select New Object, and specify where to place the section:

   If you want to…	Then…
   specify a location graphically	click (Pick Point), and specify the location for the new section object in the drawing.
   specify the coordinates of the insertion point for the section	enter X, Y, and Z coordinates for the location of the new section object.

8. Click OK.

   A 2D or 3D section is created from the section line properties and the selected objects in the building model. The section is linked to the building model. If you make changes to the building model after you create the section, you can update the section to reflect the changes.

You can edit certain characteristics of the section to control its placement and appearance.

You can also use a 2D section style to control the display of selected objects in a 2D section, and you can control the display of individual lines in a 2D section.
