Face Analysis
Using the Analyze Shape toolbar or AnalysisFace from the pull-down menu,
Radius, Reflection, Slope, and Distance allow you to select faces for the display
of temporary color analysis. These displays can be useful for detecting
inflections or variations in face curvature as well as for obtaining approximate
numerical data such as minimum radius, slope relative to a vector, or distance
from a plane.
Radius allows you to check the curvature properties of the faces.
Reflection allows you to map lines or an image onto the faces to check the
reflective characteristics of the faces.
Slope allows you to analyze the angles of the face relative to a specified vector.
Distance allows you to analyze the distance of the face from a specified plane.

NOTE
After completing a face analysis task the display mode
can be changed by using MB3 → Display.
Resolution
The Resolution option lets you set the tolerance for the face analysis display,
enabling you to adjust the quality and performance of the face analysis display.
You can choose from the following options: Coarse, Standard, Fine, Extra Fine,
Ultra Fine, and Customize.
NOTE
For more information on Resolution, please see the
Unigraphics Online Documentation.
Face Selection
Once you have selected faces for analysis, they remain selected, even after you
exit from the analysis dialog.

If necessary, use the Re-highlight Faces button to identify which faces are
selected.
You can use the Reverse Normal option to reverse the normal vectors of any
face. This option only reverses the normal for analysis purposes.
Usage Notes for Face Analysis
When making qualitative decisions, a designer/stylist should decide
which analysis type best suits the specific purpose for checking the
aesthetic characteristics of the faces.

Analyzing Surfaces
Radius Type
Gaussian radius for each checkpoint is indicated by colorĆcoded output
according to the Gaussian Radius of curvature for the face at that point.
Maximum and Minimum radius analyzes the maximum and minimum radius of
curvature at each point on the face.
Mean radius analyzes the average of the maximum and minimum curvature at
each point on the face.
Normal radius displays the radius based on a normal section plane, defined by
the surface normal and the reference vector at each analysis point. If the vector
is parallel to the surface normal, the normal curvature at that point is set to 0.
Sectional radius displays the radius based on a section plane parallel to the
reference plane. You can select a plane, datum plane, or solid face (surface type
is plane) as the reference.
U radius is the radius in the U direction.
V radius is the radius in the V direction.
Sectioning Plane
Consider a particular point P on a face. Let N be the face normal vector at P.
Any plane containing the point P and the vector N will intersect the face in
some curve through P. This plane is called the sectioning plane." As the
sectioning plane rotates about N, a family of intersection curves will be
produced as shown below. These curves can be used to analyze the curvature of
the face at the point P. This is done internally and no actual curves are output.

Choose Analysis→Face and choose the type of analysis you wish to
perform (or choose the desired analysis type from the icons on the
Analyze Shape toolbar).
If performing Radius analysis, choose the Analysis Type.
For Radius analysis, select a display type. If using Contour Lines,
specify the number of lines.
For Reflection analysis, specify the type of image, number of lines, the
direction, line thickness (if applicable), and face reflectivity.
Choose the desired display resolution.
Select the face(s) you wish to analyze.
Choose Apply to see the analysis result.

Choose Apply and then compare the radius values indicated
by the color coding with the circles that were used to create
the feature.
Choose OK.
Step 3 Use a V radius analysis to check the radii of the face
perpendicular to the section strings.
Choose Face Analysis-Radius.
Set the Radius Type to V.
Notice that you do not need to select the face. It is still selected
from the previous analysis.
Choose Apply and notice the color where the radius values
switch from negative to positive. This signifies the inflection
area where the curvature flips from one side of the face to
the other.
Choose OK.
Step 4 Close the part.
This concludes activity 11-1.
