No picture showing up in mach 3

OK I have a G-code for my drawing and when I send it to Mach 3 no picture of the drawing comes up. Does anyone know why this is happening?

I don’t know much about Mach 3 but if you post your gcode here, we could tell you if it has a valid design.

I know my G code is valid cuz we used on my buddies mach 3 set up and it worked fine.

Maybe the view is very zoomed out so it looks like nothing is there?

have you tried loading one that worked before to see if shows the pic?
