# Analyze objects

Analyze objects for errors and repair possibilities.

## Check for errors

Check

Report errors in an object's data structure.

CheckNewObjects

Report errors in an object's data structure as it is created or imported.

SelBadObjects

Select all objects that do not pass Check.

ShowEdges

Highlight edges of surfaces and polysurfaces. Displays the Edge Analysis control.

## Analyze object

Angle

Report the angle between two picked or defined lines.

BoundingBox

Creates a polyline or solid that encloses objects.

CrvDeviation

Report the maximum and minimum distances between two curves.

Curvature

Evaluate the curvature of a curve or surface.

CurvatureGraph

Evaluate curve or surface curvature with a graph.

Diameter

Report the diameter of a curve at a specified point.

Dir

Display and edit an object's normal direction.

Domain

Report the domain of a curve or surface.

DraftAngleAnalysis

Visually evaluate surface draft-angle using false-color analysis.

DraftAnglePoint

Place a point object on a surface the surface's draft angle break location.

ExtractCurvatureGraph

Duplicate a curve's curvature graph.

List

Report information about object's data structure.

Radius

Report the radius of a curve.

What

Report object properties details.

## Analyze surface quality

CurvatureAnalysis

Evaluate surface curvature using false-color analysis.

EMap

Visually evaluate surface smoothness using an image bitmap reflected in the surface.

Zebra

Visually evaluate surface smoothness and continuity using a stripe map.

## Compare objects

EvaluateUVPt

Report the u- and v-coordinates of a specified location on a surface.

MarkFoci

Place point objects at focus locations of conic curves.

GCon

Report the geometric continuity between two curves.

PointDeviation

Report the distance between points and a surface.

ThicknessAnalysis

Use false-color display to evaluate the thickness of a solid.

## Repair objects

Flip

Reverse the normal direction of a curve, surface, or mesh.

MeshRepair

Open the Mesh Repair wizard.

Untrim

Remove trim curves from trimmed surfaces.
