Centroid Point

This command draws points at the centroids of the selected polylines. In the section option, the areas need to be closed polylines representing the blocks to calculate the centroids of. This is useful for calculating haul distances and blast distances in section view. When choosing to come from a grid file, it finds the x,y position for the center of mass. Typically this grid would be the difference between existing and design surfaces, represented as a thickness grid. For example, this routine could be used to find the center of mass for a stockpile using a difference grid of the stockpile grid and base grid.
