Positioning Planes with respect to a Geometrical Target

You can position section planes with respect to a geometrical target (a face, edge, reference plane or cylinder axis). This task illustrates how to position a section plane on a geometrical target.
Open the AssemblyConstraint02.CATProduct document.
1. Click the Sectioning icon. The Sectioning Definition dialog box appears and the section plane is automatically created.

A Preview window, showing the generated section, also appears. The generated section is automatically updated to reflect changes made to the section plane.

2. Click the Geometrical Target icon in the Sectioning Definition dialog box to position the plane with respect to a geometrical target.
3.  Point to the target of interest:

A rectangle and vector representing the plane and the normal vector of the plane appear in the geometry area to assist you position the section plane. It moves as you move the cursor.

4. When satisfied, click to position the section plane on the target.

Notes:
To position planes orthogonal to edges, simply click the desired edge.
A smart mode recognizes cylinders and snaps the plane directly to the cylinder axis. This lets you, for example, make a section cut normal to a hole centerline. 

To de-activate this mode, use the Ctrl key.
5. (Optional) Click the Reset Position icon to restore the center of the plane to its original position.

6. Click OK in the Sectioning Definition dialog box when done.
