Adobe Illustrator equivalent for Ubuntu

[Kipton Moravec]

I am looking for a program to let me design front panels for electronic
boxes.

I need to be able to place circles and shapes for cutouts at precise X Y
coordinate positions, and place text and graphics in precise locations
relative to the cutouts and overall size and shapes.

If it outputs in a vector format as opposed to dot-matrix format that
would be even better. 

Is there such a thing, or am I just dreaming?
