# 3D Cross-Section Functions

The In-Sight 3D Cross-Section functions allow you to extract 2D cross-sections or profiles from a 3D point cloud A point cloud is a 3D structure that consists of the data points collected by a 3D vision system during acquisition. along a Region of Interest. You can further analyze the geometric information provided by the 2D profile using Profile tools to verify that an object is defect-free and meets specifications. Applications include:

- Inspecting glue and weld seams
- Verifying component height
- Identifying surface defects
- Measuring gaps, diameters, or thickness

3D Point Cloud with Cross-Section Tool | Profile View

The following functions are available in the 3D Cross-Section 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. group:

- ExtractCrossSection3D: Extracts a profile from a point cloud using the points that intersect with a user-defined 3D rectangle.
- ExtractParallelCrossSections3D: Extracts multiple parallel 2D profiles from a user-defined 3D Region of Interest within the point cloud.
