Drawing with automatic geometry mode
You have a choice of freely drawing Operational Activity symbols and ICOM arrows on OV-5 diagrams, or invoking the automatic geometry drawing mode. When this mode has been turned on for an OV-5 diagram, the modeling software controls placement of Operational Activity symbols and ICOM arrows to predefined positioning.
