When called from the Graphics window, this saves the active data set to its current name and directory. If you have changed the orientation from that specified in the Initial Orientation dialog in the File2 menu, you are asked if you want to save the current orientation. If you choose to do this, the current orientation will be converted to initial orientations on the observer x, y and z axes
When you save a data set for the first time, SHAPE displays the Save As dialog box so you can name your data set. If you want to change the name and directory of an existing data set before you save it, choose the Save As command.
