Symmetry Check
Symmetry Check 
checks for geometric symmetry in parts about a plane. It
identifies symmetrical, asymmetrical, and unique faces.
In parts with multiple configurations, Symmetry
Check works with the current configuration only. Once you identify
symmetrical entities, you can work on a portion of the model, which saves
you design time and increases performance.
Type of Check (Parts only)
Manual Face Check
Automatic Symmetry Split. Reduces
a part to its smallest repeatable symmetrical body, which is especially
useful when you run analyses using simulation software.
Analysis Parameters
Defined by. Defines how to define
the plane of symmetry.
Single plane Specifies symmetry with respect to a selected plane.
Two parallel
faces. Places the plane mid-plane between the two faces.
Two points.
Places the plane perpendicular to the midpoint of the line joining the
points.
Check. Checks for symmetry about
the plane and lists results under Symmetry
Check results.

After you check for symmetry, these components appear under
Symmetry Check results.
Symmetry Check Results
When you click Check under Analysis parameters, the results appear
here. Click listed faces or components to highlight them in the graphics area.
Save report. Saves the results
in an HTML report.
Recheck. Clears the results
so you can run a new symmetry check.
Symmetry Check Results - Parts Examples
|
Unique faces. Exist on only
one side of the plane of symmetry and do not contact it.
SideA
and SideB
are on opposite sides of the plane of symmetry. |
|
|
Cut faces. Contact the plane
of symmetry.
Symmetric cut face
Asymmetric cut face |
|
|
|
|
Uncut faces. Do not contact
the plane of symmetry. Faces are shown in pairs.

Symmetry Split
Hover over areas of
the model to preview the smallest symmetrical bodies to which you can
reduce the part.
Select a body.
The body name appears under Body
for Split.
Click Split
Part.
The model is reduced to the selected body.
A Split feature appears in the
FeatureManager design tree.
