Check translated data for quality (Geometry Analysis)

1. In the part browser, double-click the Construction folder to enter the construction environment. Alternatively, you can right-click the Construction folder and select Edit Construction.
2. Select solids or surfaces to examine, using one of the following methods:
   • 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.
3. Select Examine to check the data.

Geometry Analysis

Geometry is used in the generation of bodies. Geometry errors can cause errors in modeling, including topology errors. Geometry Analysis lists bodies or surfaces with geometry errors and groups them by error type. Repair geometry errors before attempting to repair topology errors.

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 may 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.
