Trying to design a PCB, with curves and in metric (ie no INCHES)
The image is the sort of design i have, it was done in INKSCAPE and saved in PNG to show what i am doing
as most places dont let you upload SVG

Mod edit: language

So any SOFTWARE that is VECTOR so i can get the figures right, to be able to put in a GERBER format (whatever way, ie save to one format and then use another bit of software to convert it) also i just note i am on LINUX and any PLUGIN i would need some FOOL PROOF way to installing it or PICTURE (Love them coloured pictures)

 

EAGLE and probably other PCB packages allow manual entry of point coordinates and arcs with fills on multiple layers. When I've done something like you show, I drew it on AutoCAD to save some math (and its easier to edit), took the end points / radii etc. from CAD and plugged them into EAGLE then used polygon fills. Works fine.

You might also consider the old fashioned way i.e. draw it in whatever program you want, make a high-quality print and take it to a photo-house to make the PCB films. Look around for a 'reprographics' outfit and ask them what they can do for you. You'd also have to check with the PCB manufacturer to see if they can take films as most use gerbers these days.

There are members here who etch their own PCBs and have posted a lot of good information here http://forum.allaboutcircuits.com/threads/project-photographic-methods-of-making-pcbs.107696/ and here http://forum.allaboutcircuits.com/threads/project-how-to-make-pcbs.47681/ and here http://forum.allaboutcircuits.com/threads/my-new-etching-tank.117346/ for openers.

Welcome aboard and good luck.
