How do you make a line hatch gradient that changes in density and scale?

[Song258659718ska]

I keep seeing this type of cross-section drawing of soil where the hatch or fill slowly diminishes in density. It looks like the blend tool but not exactly. Was wondering if anyone knew a script, plugin, or something that does this gradient like this.

Astute Graphics Stipplism can do that.

I did look at that but it's not exactly a stipple. The effect I'm looking for isn't dots but more like outlines of circles or amorphic ellipses.

You can define your individual symbols to use for that.

Oh wow. Sorry, I guess I didn't look hard enough. That's exactly what I wanted! Thank you so much!

I'm glad you can solve it.

You might have to dive deeper into the options of that panel in order to figure out good settings for your art.
