      This difference is intended. The origin of geometry-defined coordinate systems is calculated with the following formula:origin = (sum of each selected geometry’s position) / (the number of selected geometries) The centroid of the summary in the selection information table is calculated with the following formula: centroid = (sum of each selected geometry’s position multiplied by the selected geometry’s “weight”) / (the total “weight” of the selection) where a geometry’s weight is defined as edge: length face: surface area body: volume.
