# ProfileExtractTangentLine3D Vision Data Access functions

This section lists the available 3D Vision Data Access functions that get values from a ProfileExtractTangentLine3D 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
--- | ---
GetFarPoint(ProfileExtractTangentLine3D, [Index]) | Returns the farthest Point3D of the profile from the extracted tangent.
GetLine(ProfileExtractTangentLine3D, [Index]) | Returns a Line3D structure for the extracted line.
GetNearPoint(ProfileExtractTangentLine3D, [Index]) | Returns the nearest Point3D of the profile to the extracted tangent.
