Create cross sections
Displaying a cross section of a 3D model is like cutting it in half and looking inside. Use the Cross Section Controls
dialog box to adjust the alignment, offset, and tilt of the cutting plane.
Before and after cross section
1 Click the Toggle Cross Section icon on the 3D toolbar to turn on or off the cross section.
2 (Optional) Click the arrow next to the Toggle Cross Section icon, and choose Cross Section Properties, which
opens the Cross Section Controls dialog box. Then do any of the following:
• Change settings under Alignment, Display Settings, and Position And Orientation.
• Click the Save Section View button to save the current cross-sectional view. (The saved view will appear on the
Views menu in the 3D toolbar and in the View pane of the Model Tree with a default name, SectionView[n].)
Cross Section Controls options
Changes you make here are applied immediately. To see these changes, make sure that the Cross Section Controls
window does not block your view of the active 3D model. The Cross Section Controls window remains on top if you
focus or interact with the underlying PDF. To close it, click the Close button in the upper right corner.
Enable Cross Section When selected, makes the other options available.
Alignment Determines the axis (x, y, or z) to which the cross section aligns.
Align To Face Cuts the cross section on a plane defined by the surface of any face that you then click in the 3D model.
Align To 3 Points Cuts the cross section on a plane defined by any three points that you click on the 3D model.
Show Intersections Indicates where the cutting plane slices the 3D model by adding a colored outline. Click the
color swatch if you want to select a different color.
Show Cutting Plane Displays the two-dimensional field that cuts the 3D model. Click the color swatch if you want
to select a different color, and enter a different percentage if you want to change the opacity of the plane.
Align Camera With Cutting Plane Rotates the 3D model so that it’s level with the cross section’s cutting plane.
Offset Determines how much of the 3D model is sliced. Drag the slider left or right, or change the percentage.
