I just started using SW2020 and I noticed that when I correct a sketch that has dangling relationships, these green phantom lines appear (see attached) and won't go away, even if I hide all display types - any suggestions?
even when you've closed the sketch? Have you tried Ctrl+Q?
To clarify, they are only visible while editing the sketch, so it's only annoying while I'm editing the sketch.
Check your system Color settings
Thanks for the tip - by checking the colors I determined that they were "inactive control polygon handles". I'm used to seeing these on splines I've created but not entities created by intersection, as is the case here. I can shut them off for individual splines via the RMB menu, but:
1) One of them won't go away no matter what.
2) It zig zags all over the place, being way larger than the spline or even the part. (see pictures).
Now that I know what it is I'll submit an bug report.
It's difficult to tell from your screenshot, but they may be spline control polygons. If you have splines in your sketch, you can right click on them and select 'Display Control Polygon' to toggle the display:
