How do I fit a big power system in the DIgSILENT Power Factory Graphic Window?

[Carlos V. Dominguez]

Hi there. I learning how to use DIgSILENT Power Factory to do my thesis of my specialization in power systems. I have already done load flows of a 16 bus power system. I need to draw a 24 bus power system but I don't know how to fit this big system in the small graphic window. I could draw a 16 bus system but I need more space for de 24 bus system of my thesis. Con anyone please help me on this matter? What is the command to enlarge the graphic window? Thanking you in advance for your attention, I remain, sincerely, Carlos V. Dominguez from Caracas Venezuela.
