Section and then click Planar. The Section tab opens.3. Select a planar surface, datum plane, or coordinate system axes reference to intersect the model. A cross section is automatically created. A dragger appears at the center of the clipping plane. The dragger is normal to the clipping plane and indicates the clipping direction.
The Section reference collector on the References tab displays the name of the reference used to create the cross section.
 | Alternatively, you can choose to first select the planar surface, datum plane, or coordinate system axis and then launch the Section tool. |
4. Select the constraint type from the drop-down list:
◦ Offset—Creates the cross section at the specified distance from the selected reference. Click and type a value for the offset distance.
◦ Through—Creates the cross section along the selected reference.
