Used to project all points onto a surface or plane. Upon executing the function, a menu will open, prompting the selection of three points to define the plane/surface. Note that there must already be three points along the plane in the CRD file in order for this function to work properly. After selecting the three points (the "List" buttons will bring up a list of available points), select "OK" to proceed. A screen similar to the Store Points dialog will now open. Every point which is read will be plotted along the plane defined by the three points selected, even if it is at a different distance. When finished, simply exit out of the menu as with any other function.
