In this Lesson, the tools used for face analysis will be discussed. The face analysis tools may be found on the Analyze Shape toolbar. Face Analysis Icons Face Analysis Icons Deviation Gauge Section Analysis Grid Section Analysis Graph Graph Options... Output Listing Face AnalysisReflection Output Listing Options... Face AnalysisRadius 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. 11-2 Industrial Design With Shape Studio EDS All Rights Reserved Unigraphics NX Analyzing Surfaces ÏÏÏ ÏÏÏ 11 ÏÏÏ ÏÏÏ Display Type (for Radius, Slope, and Distance) This option allows you to select the type of display to use.

Use the Spike Length field to specify the length of the color-coded spines, using the current Unigraphics units of measure (e.g., inches).

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. 11-4 Industrial Design With Shape Studio EDS All Rights Reserved Unigraphics NX Analyzing Surfaces 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.

Gaussian Maximum Minimum Mean Normal Sectional U V Fringe Hedgehog Contour Lines Coarse Standard Fine Extra Fine Ultra Fine Customize... 11-6 Industrial Design With Shape Studio EDS All Rights Reserved Unigraphics NX 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.

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.

Top face ZC YC XC Isocline curves Step 2 Use a Sectional radius analysis to check the radii of the face relative to the XC-ZC plane.  From the Analyze Shape toolbar, choose Face Analysis-Radius.  Set the Radius Type to Sectional.  Choose the Reference Plane button.  Choose the Principal Plane button.  Choose ZC-XC Plane.  Set the Display Resolution to Extra Fine.  Select the top, curved face.

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.
