Distance between point and plane

how can i calculate the distance between a point and a plane?
the segment that calculates the distance must be perpendicular to the plane and I’m not able to create it perpendicularly…

A very simple method is to transform the point in the plane’s coordinates system as it is shown in this example in the script repository. The distance from the plane is the third coordinate of the point in the plane coordinate system (point_Plane[2]).
