I need to design some analogue meter scale cards to fit in some repurposed VU meter mechanisms.
I intend inkjet printing them onto some old overhead transparency stock, but I need them to be as accurate as I can, so a freehand drawing will not work.
Can anyone recommend a package which allows accurate arcs and angles to be drawn, and symbols and numerals to be placed, to run on Ubuntu?
I use LibreOffice Draw for that sort of stuff. It is quite like PowerPoint but has better measuring capabilities (AFAIK - very long time since I used PowerPoint)
I have used LO Draw for designing parts to be cut on a Silhouette Portrait cutter. It easily gets a precision better than 0.5mm
I use EAGLE for that sort of drawing. While it's normally used for PCBs, that means that it has a bunch of layering and close-tolerence output features, as well as nice things like polar coordinates and a programming language to let you generate parts of your drawing parametrically.
Like these, for instance (although, these are actually supposed to be real PCBs.)
