Easily Analyze Hole Locations using Primitive Center Point Deviations
When reviewing hole locations, being able to visualize the magnitude and direction of the deviation of the measured primitive center from the nominal location can help in detecting and understanding manufacturing problems. Starting in PolyWorks|Inspector 2018 IR9, you can easily display primitive center point deviations in the 3D Scene along the X, Y, and Z axes for all point-reducible features. This allows you to show to what extent, and along which axes, holes are deviated so that manufacturing errors can be analyzed and corrected.
Step by step: To show primitive center point deviations in the 3D Scene:
- Make sure a measured hole feature is visible in the 3D Scene
- Right-click the hole feature in the Tree View, then choose View > Deviations > Restore on the shortcut menu that is displayed.
- Click the Object Display Options button on the 3D Scene toolbar. An options list is displayed.
- Navigate to the Features section and set Deviation type to Primitive Center Points. Based on controlled dimensions set in the Geometry Controls pane, namely X, Y, and Z, up to three deviation vector components are displayed along the standard axes, representing the primitive center point deviation. As shown in the image, the value for each deviation vector component is represented by its color, according to the displayed color scale.
- Optional: To display the numeric value of center point deviations, select Show deviation values when possible.
NOTE: If X, Y, and Z dimensional controls are assigned a specific coordinate system in the Edit Context dialog box of the Control Reviewer pane, primitive center point deviations are displayed using the specified coordinate system.
