# ExtractCircle3D Vision Data Access functions

This section lists the available 3D Vision Data Access functions that get values from an ExtractCircle3D structure.

Function Functions are tools that are available in Spreadsheet for processing and analyzing acquisitions or other results. You can add functions to your Spreadsheet job to create tool chains and produce results for specific applications. | Description
--- | ---
GetAxis(ExtractCircle3D, [Index]) | Returns the axis of the extracted circle as a Line3D structure.
GetCircle(ExtractCircle3D, [Index1], [Index2]) | Returns the extracted Circle3D structure specified with the index.
GetCoverage(ExtractCircle3D, [Index]) | Returns the coverage of the circle specified with the index. Coverage is the percentage of the region perimeter that is covered by the circle.
GetNFound(ExtractCircle3D) | Returns the number of found circles.
GetScoreExtractCircle3D, [Index1], [Index2]) | Returns the score of the circle specified with the index as a value between 0 and 100.
GetTransitionType(ExtractCircle3D, [Index]) | Returns the transition type of the specified 3D circle (1 = convex; 2 = concave).
GetTransitionTypeText(ExtractCircle3D, [Index]) | Returns the transition type of the circle specified with the index as a text (convex or concave).
