Rendering and Interpolation rollouts
All spline-based shapes share these parameters.
See
Splines (page 1–261) for an explanation of
these parameters.
Section Parameters rollout
Create Sha pe—Creates a shape based on the
currently displayed intersection lines. A dialog is
displayed in which you can name the new object.
Theresultingshapeisaneditablesplineconsisting
of curve seg ments and corner vert ices, based on all
intersected meshes in the scene.
Update group
Provides options for specifying when the
intersection line is updated.
When S ection Moves —Updates the intersection line
when you move or resize the Section shape.
When S ection S el ected—Updates the intersection
line when you select the section shape, but not
while you move it. Click the U pdate Section button
to update the intersection.
Manually—Updates the intersection line only when
youclicktheUpdateSectionbutton.
Update Section—Updates the intersection to match
the current placement of the Section object when
using When Section Selected or Manually option.
Note: When using When Sec t ion Selected or
Manually, you can offset the generated cross
section from the posit ion of the i ntersected
geometry. As you move the section object, the
yellow cross-section lines move with it, leaving
the geometry behind. When you click Create
Shape, the new shape is generated at the displayed
cross-section lines in the offset position.
Section Extents group
Choose one of these options to specify the extents
of the cross-section generated by the section
object.
Infinite—Thesectionplaneisinfiniteinall
directions, resulting in a cross section at any mesh
geometry in its plane.
Section B oundary—The cross-sect ion is generated
only in objects that are within or touched by the
boundary of the section shape.
Off—No cross section is displayed or generated.

Co lor swatch—Click this to set the display color of
the intersection.
