The Wireframe Checker identifies features on a part by fitting line and arc segments to the polylines of curves and to the uv and trim lines of surfaces. It then uses these lines and arcs to construct 2D features, cones, cylinders, spheres, and tori. The CAD Processor Options dialog controls the sensitivity with which the Wireframe Checker analyzes and identifies features on the CAD model.
- Choose .
- Right-click the CAD view and choose .
- In the CAD Processor Options dialog, edit the tolerance values:
- Curvature tolerance. Enter the maximum radius variation for fitting curved features. Curves exceeding this value are not recognized.
- Minimum segment length. Enter the minimum length of segments that can be used to identify cones, cylinders, planes, spheres, tori and 2D items.
- Entity tolerance. Enter the maximum value by which a feature can differ from the nominal and still be identified. For example, when the measured arcs of a slot differ from nominal by more than the specified tolerance, PowerInspect does not recognize the feature as a slot. Similarly, when surface features are further from the corresponding CAD surface than this tolerance, the features are not recognized.
- Planar tolerance. Enter the maximum value by which a plane can deviate from its nominal. When the feature deviates from the nominal by more than the specified value, it is not recognized as a plane.
