For construction documents, I often stack viewports and have a bottom vport, transparency layer, top vport to make certain things pop. But if you want to snap a dimension to something on the bottom vport, the transparency layer is in the way, meaning you have to toggle layer visibility to snap to it, which isn’t terrible, but extra steps.
With the Enable Draft Mode on (Pan and Zoom only, half-second redraw delay), you can dimension something on the bottom layer while zooming as it makes the transparency layer disappear temporarily. Saves some clicking.
If that isn’t gibberish to you, the congrats you learned the trick too.
I’ve been using that feature the last few weeks to get exact snap points. I wonder if there is a way to make it last longer than a half second. There are times I could use a whole second or maybe two. Or even keep it on until done dinensioning.
And if that 3 seconds becomes too annoying every time you pan/zoom, you can enable/disable draft mode with a keyboard shortcut command. I don’t really use draft mode that way though. I’ve gotten use to it always being on with the 0.5 sec redraw to improve general LO performance.
