Evaluate > Check model

Checks all, visible, or picked objects for common problems that may prevent data transfer.

See Check objects for modeling problems

See Prepare a model for import into CAD systems

Check

Check only surfaces, only curves, or both. The default is Surfaces.

Objects

Check all objects, all visible objects, or picked (active) objects. The default is Visible.

Report

Errors: only show objects that failed one of the checks.

All: show all objects even if they pass the checks.

The default is Errors.

Check Model Parameters

Rationals

Check for rational geometry.

Periodics

Check for periodic (closed) objects.

Multiple trim regions

Use this check to find instances where trims have made a single surface look like separate surfaces, which can confuse some CAD software packages.

Multiple knots

Check for multi-knots (multiple edit points at the same point in space that may create a sharp corner in a curve or surface).

Internal Tangent discontinuity

Report objects with internal tangent discontinuities due to multi-knots.

Non-Planar Curves

Check for curves that are not planar. This option only appears when Check is set to Curves or Both.

Product Data Quality Recommended Checks

Duplicate Geometry

Report curves and surfaces that are duplicates of, or embedded into other curves and surfaces, within the tolerance given in the text field.

Short edges

Check for edges (including trimmed edges) shorter than the distance specified in the text field.

Tiny Spans

Check for curves and surfaces whose interior span/isoparm configuration results inthe length of a span (or the length of both opposing patch segments for surfaces) being smaller than the distance tolerance specified in the text field.

Indistinct Knots

Check for curves and surfaces whose interior span/isoparm configuration results in knots being closer in parameter value than the tolerance specified in the text field.

This check does not report multiple knots for which a separate check already exists (see Multiple Knots above).

Minimum Radius of Curvature

Report surfaces that have a radius of curvature smaller than a user-defined value. The smallest radius found on those surfaces will be reported.

Curve or Surf-Boundary Self-Intersect

Report curves, surface boundaries, or trimmed surface boundaries that contain interior self-intersections. A self-intersection refers to the curve or surface boundary intersecting itself at one or more locations that are not both endpoints.

Trimmed-Surf Boundary Intersect

Report trimmed surfaces containing boundaries that intersect other boundaries on the same surface, within the tolerance supplied in the text field.

Maximum Degree

Check for objects with a degree higher than the number specified in the text field.

Maximum Spans

Report curves and surfaces that contain a number of spans exceeding the value specified in the text field.

Surface or Planar Curve Waviness

Report surfaces or planar curves that have more than a user-defined number of inflections (change in curvature sign) over their entire length (or width for surfaces). The maximum number of inflections allowed is entered in the text field (default is 3).

Allowed Inflections Per Span

This field only appears when Surface Curvature Waviness is ON. When turned on, it controls the maximum number of inflections per span allowed for a surface to pass the waviness test, in addition to the overall number of inflection permitted (see previous option). The default is 1.

Normal Consistency

Check for surfaces whose normal's direction is inconsistent with the normal's direction of adjacent surfaces.

Max. Gap Distance - G0

Report objects that exceed a user-defined tolerance for positional continuity between adjacent curves or surfaces.

The tolerance value is given by Maximum Gap Distance in the Tolerances Continuity section of Preferences > Construction options .

The Topology Distance tolerance (in Preferences > Construction options ) must be larger than the Maximum Gap Distance for this check to find gaps.

See Maximum Gap Distance

Tangent/Norm Angle - G1

Report objects that exceed a user-defined tolerance for tangent continuity between adjacent curves or surfaces.

The tolerance value is given by Continuity Angle in the Tolerances Continuity section of Preferences > Construction options .

See Continuity Angle

Curvature - G2

Report objects that exceed a user-defined tolerance for curvature continuity between adjacent curves or surfaces.

The curvature deviation is calculated as .

The tolerance value is given by Continuity Curvature in the Tolerances Continuity section of Preferences > Construction options .

See Continuity Curvature

Report Parameters

Tangent/Norm Angle Limit

Maximum angle allowed between the tangents (or normals) of objects for them to be included in the G1 continuity test.

Curvature Limit

Maximum curvature deviation allowed between objects for them to be included in the G2 continuity test.

G0, G1, G2, and Normal Consistency checks are only performed if the maximum distance between the objects is less than the Topology Distance found in Preferences > Construction options .
