+This pipeline command does what its name suggests: it transforms signals from one coordinate system to another. A popular use case for this command is to transform signals from the [[visual3d:documentation:definitions:laboratory_coordinate_system|Lab Coordinate System]] to a [[visual3d:tutorials:modeling:virtual_laboratory|Virtual Lab Coordinate System]], for example when a participant turns around and walks back to their initial point.

+==== Notes ====
+==== Examples ====
+Moving force plates [[visual3d:documentation:kinematics_and_kinetics:external_forces:dynamic_force_platforms#example_2|can be modelled]] using a process that leverages the Transform_Data_Coordinate_System command. The premise is that once you create segments representing the force platform and move it to the lab origin (aligned with the lab coordinate system), you transform your [[Visual3D:Documentation:Visual3D_Signal_Types:FORCE_Data_Type|FORCE]], [[Visual3D:Documentation:Visual3D_Signal_Types:COFP_Data_Type|COFP]] and [[Visual3D:Documentation:Visual3D_Signal_Types:FREEMOMENT_Data_Type|FREEMOMENT]] signals from the force platform at the origin to the moving platforms.
