Snapping a vertex to an edge of a BG object using edge slide?

I’m trying to snap a vertex in edge slide mode to the edge of a background objects but it doesn’t work. I love how well snapping works in Blender but sometimes I want to do some tricky snapping that does not fit into any of the settings in the snapping menus like snapping a vertex from the front view to the edge of a background object that is angled, for example.

Does anyone know any snapping tips to some of the issues mentioned above or just nifty snapping tricks that aren’t obvious?

Just though I’d ask.

Cheers,

With the latest version 2.9 this is possible, it this is not working there is another issue.
Post a screenshot so we can take a look at it.

Ah, so it’s only version 2.9 onwards then?

I was using 2.83 for my project so it was not behaving like it does in 2.9.

Thanks for that info.
