# ProfileExtractCornerPoint3D Vision Data Access functions

This section lists the available 3D Vision Data Access functions that get values from a ProfileExtractCornerPoint3D 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
--- | ---
GetCorner(ProfileExtractCornerPoint3D, [Index]) | Returns a Point3D structure for the corner with the specified index in the corner extraction function.
GetCornerAngle(ProfileExtractCornerPoint3D, [Index]) | Returns the angle of the corner with the specified index in the corner extraction function.
GetCornerSegment0(ProfileExtractCornerPoint3D, [Index]) | Returns aLine3D structure for the first line segment used by the corner extraction function for defining the corner with the specified index.
GetCornerSegment1(ProfileExtractCornerPoint3D, [Index]) | Returns a Line3D structure for the second line segment used by the corner extraction function for defining the corner with the specified index.
GetCornerType(ProfileExtractCornerPoint3D, [Index]) | Returns the type of the corner, convex or concave, with the specified index in the corner extraction function.
GetNFound(ProfileExtractCornerPoint3D) | Returns the number of corners that the corner extraction function found in the profile.
GetTangentAngle(ProfileExtractCornerPoint3D, [Index]) | Returns the tangent angle of the corner with the specified index in the corner extraction function.
GetX(ProfileExtractCornerPoint3D, [Index1],[Index2]) | Returns the X coordinate in the 3D point cloud A point cloud is a 3D structure that consists of the data points collected by a 3D vision system during acquisition. for the corner with the specified index in the corner extraction function.
GetY(ProfileExtractCornerPoint3D, [Index1],[Index2]) | Returns the Y coordinate in the 3D point cloud for the corner with the specified index in the corner extraction function.
GetZ(ProfileExtractCornerPoint3D, [Index1],[Index2]) | Returns the Z coordinate in the 3D point cloud for the corner with the specified index in the corner extraction function.
