# PlaneXY

The PlaneXY 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. is used to quickly construct a Plane3D structure, positioned at the origin and oriented towards the +Z axis.

Use this function to construct a plane if you cannot use any reliable features on the point cloud A point cloud is a 3D structure that consists of the data points collected by a 3D vision system during acquisition. to measure from along the Z-axis. For example, if the configured application is inspecting the top part of a tall object, and the conveyor surface (on which the object is transported) is outside the vision system's field of view, you can use the PlaneXY tool to measure from any height, as long as neither the vision system nor the conveyor has any vertical movement on the Z-axis.

Tip: You can construct additional parallel or perpendicular planes by using the fixed plane of this tool, with the ParallelPlane3D and PerpendicularPlane3D functions, respectively. This allows you to use the vision system's FOV features to construct other geometric shapes.
