Hi,
what screenset are you using? I use a somewhat customised version of wx4.set. The customisations have nothing to do with the toolpath display.
It doesn't matter if the toolpath is for plasma, laser or mill, it is displayed indentically.
There are 29 API calls to do with the toolpath. Have you investigated any or all of them? These are the only way for ANY screenset to generate a toolpath,
that's why its called an API. If none of these calls help you, and to be honest my inspection and reading of them suggests not, then you must address the line
width issue in your PCs graphics.
My feeling is that your background colours are too dark too offer contrast with dark traces. Use a light background with dark traces OR a dark background with
light traces. The previous screenshot is plainly visible but needs be expanded to seperate the detail.
