If I cut apertures in plastic cases I drill holes almost up to the line at slow speed in a pillar drill with the plastic supported underneath on a block of wood and held down firmly so that it doesn't 'ride up' the drill bit, then I use a sharp woodworking chisel and craft knife to pare away the waste up to the line. (Plastic doesn't respond well to files). You need to pare away thin slivers of plastic at a time and keep good control of the tool. You can always take a bit more off, but you can't put it back on!
When I scribe lines I do it from both ends to meet in the middle and have the rule so that the line is on the waste side. That way, you don't get lines where you don't want them.
It's amazing how discerning the eye can be at detecting small defects, as we known only too well!
I'm one of those insufferable pedants who - when visiting other people's houses - feel an irresistible urge to straighten wonky pictures and mirrors. Probably borderline OCD, if not full blown.
As quality controller of my own work, I often reject it as sub-standard at the first attempt, then do it again, and hopefully get it right.
