Quality Check dialog box

Analyzes translated data and provides diagnostic information. Reports errors found and suggests repairs. Analyzes data types separately or all at once. Analysis can be stopped and restarted without repeating examination of already analyzed data. Right-click a body, surface, or wireframe with an error to locate it in the graphics window.

Access:

In the part browser, double-click the Construction folder to enter the construction environment. To start, do one of the following, and then click Examine: On the ribbon, click Construction tab Manage panel Quality Check . Select data in the graphics window. Note: "Data" refers to solids and surfaces. Right-click the construction folder, and select Quality Check. All data in the construction folder is checked. Right-click a group node in the browser, and select Quality Check. Only data in the group node is checked. In the graphics window, click and drag a window to select solids or surfaces. Right-click and select Quality Check. Selected solids or surfaces are checked. Right-click in the graphics window, and click Select All on the context menu.

Known Issues categorizes analyzed data into groups in browser hierarchies: Topology, Geometry, and Modeling Uncertainty. Wireframes are not checked. Within each group, error issues are grouped, and bodies with errors are nested in the groups. Right-click on a body, and select Find in Browser.

Topology Analysis lists bodies or surfaces with topology errors and groups them by error type.

Topology errors

Topology errors
Loop orientation	The outer loop is going in a wrong direction compared to the face normal direction. If the face includes islands (loops enclosed within the outer loop), the normal direction of the islands must point opposite to the outer loop. Loop direction is defined by the start and endpoint and direction indicator. In addition to the loop and islands having the same direction, a surface has a normal direction that must agree with the loop direction. If any of the directions are opposite the others, an error is found.
Face orientation	The top side of a face is referred to as the surface normal. Adjacent faces within a solid must all have the same normal direction. For example, all six faces of a box must point in to be a valid solid. The loop direction is inconsistent with the normal direction of the face or inner loops do not agree with each other.
Loop connectivity	Geometry such as lines, arcs, and splines are combined into structures. Many edges and geometry can be combined into structures referred to as loops. Loops are used as boundaries on surfaces and trim a potentially infinite size to a face. Sometimes the structure of the loop is incorrect in the neutral IGES or STEP file.
Duplicate vertices	Start and endpoints of an edge are vertices. During translation, attempts are made to merge vertices that fall within the system tolerances. Duplicate vertices can occur when extremely small edges make up a complex object.
Bad face missing data	The face does not have its underlying geometric definition and is incomplete. Typically, the face cannot be used for modeling.
Bad edge missing data	The edge does not have its underlying geometric definition and is incomplete. Typically, the edge cannot be used for modeling.

Geometry Analysis lists bodies or surfaces with geometry errors and groups them by error type.

Geometry errors

Geometry errors
Self-intersecting surfaces	A surface that folds onto itself is considered a self-intersecting surface. Surfaces must be continuous and smooth without changing direction.
Self-intersecting curves	Curve data comprises lines, arcs, or splines. Curves must always be smooth without changing direction. Curves cannot reverse, twist, or intersect.
Irregular curve	Math data is inconsistent in the curve definition, or a vector is zero. This error can occur when the approximating surface does not fit within the system tolerance of the defining surface in the neutral IGES or STEP file.
Irregular surface	The generated surface was approximated during translation and did not fit within system tolerances of the original surface in the neutral IGES or STEP file. Or, a point on the surface is not pointing in the same direction as the rest of the surface. These errors can occur if surfaces are twisted or collapse into a small area.
Curve discontinuities	Curve data comprises lines, arcs, or splines. Curves must be smooth without abruptly changing direction (g0) and cannot have an abrupt transition between curves.
Surface discontinuities	The normal direction or curvature of the surface changed abruptly. The error can be caused by disconnected geometry. Surfaces must be smooth and cannot have an abrupt change in direction (g0).
Degenerate surface	The points that comprise the surface are in an area that is too small.
Singularity surface	A point on the surface vector is poorly defined. The surface normal cannot be determined.

Modeling Uncertainty lists bodies or surfaces with errors, but the system cannot determine the exact error type.

Problem Diagnosis/Description provides detailed information about a selected body listed in the Known Issues pane.

Help message summarizes the error or state of the data. Suggests how to repair the problem data.

Click for more help describes the data error in more detail.

Refit Face selects and repairs problem faces by attempting to refit them, using a maximum allowable tolerance between faces. Enabled only when the system detects geometry and modeling uncertainty issues.

Examine starts analysis on the selected data.
