Hatch Gap Marker Style Red Circles

[eimimitu]

I remember coming across a function that would highlight or mark a specified drawing area. Kind of like what you get when the hatch command detects a gap in the boundry selected. Small red circles that remain until a regen or redraw. Did I imagine it or does such a function exist?

 

I know it can be replicated by some sort of entmake or grvecs/grdraw combo... but like I mentioned I thought I remember seeing that exact function somewhere.

 

Anyway thanks for your time.
