Hatching
You can create new planar part cross-sections in a 3-D model. The following
planar cross-section types are available:
• Planar — Enables you to select a planar surface or datum plane to create a
cross-section through.
• X Direction — Creates a planar cross-section with the normal pointing
along the model’s default coordinate system X-axis.
• Y Direction — Creates a planar cross-section with the normal pointing
along the model’s default coordinate system Y-axis.
• Z Direction — Creates a planar cross-section with the normal pointing
along the model’s default coordinate system Z-axis.
These cross-section types are created using the Section dashboard. You can
access the Section dashboard from either the Section types drop-down menu
in the Model Display group of the View ribbon tab, or from the Sections tab
of the view manager.
New cross-sections are given the default names of XSEC0001, XSEC0002,
and so on. You can always rename a cross-section either during or after
creation, similar to any feature. You can also redefine cross-sections or

manage their display using either the Sections node in the model tree or the
Sections tab in the view manager.
Cross-Section Options
The following are various cross-section creation options available in the
Section dashboard:
• Distance from plane — Enables you to type a distance to offset the
cross-section from the specified reference. You can also dynamically drag
the cross-section in the graphics window.
• Direction from plane — Enables you to flip the direction from the specified
reference that the cross-section is offset.
• Cap section — Enables you to cap the surface of the cross-section.
• Fill surface color — Enables you to fill the capped surface with a specified
color. This option is only available if the cross-section is capped.
• Enable hatching — Enables you to toggle the cross-section’s hatch pattern
on or off.
• 3D Dragger — Similar to Assembly mode, you can enable the 3D Dragger
and use it to translate or rotate the cross-section about the three axes.
• View 2-D section in separate window — Enables you to display the 2-D
cross-section in a separate window.
Editing Cross-Section Hatching
If the hatch pattern is enabled for a given cross-section, you can edit the
hatching either from the Sections node in the model tree or from the view
manager. When editing the hatch pattern, the Edit Hatching dialog box
displays with the following options:
• Pattern — Enables you to edit the hatch pattern used. You can select
from a default library of ANSI or ISO hatch patterns, or choose from a
user-defined library hatch pattern.
• Angle — Enables you to specify the angle to orient the hatch pattern.
• Scale — Enables you to size the pattern. You can type a value, or use the
two options to either halve or double the existing hatch spacing.
• Color — Enables you to modify the color that the hatch pattern displays in
the graphics window.
Cross-Section Display Management
You can manage the display of a given cross-section from the Sections node
in the model tree, from the view manager, or by selecting the cross-section in
the graphics window. The following right-click options are available:
• Show Section — Enables you to enable or disable the cross-section within
the graphics window. This option enables or disables both the section
itself and the hatch pattern.
• Activate/Deactivate — Activates or deactivates cut on the geometry based
on the cross-section.
