About Drawing Layer Themes: Hatch Scale

For standard-scale hatch patterns (those that do not have an AR- prefix), the density of the hatching varies according to the hatch scale and plot scale you use.

Plot, Display, or View Scale Hatch Scale Result
1:2000 1 to 500 Solid
2000 Lines clearly visible  
15000 Sparse, occasional lines  
20000 No hatch or one line only  
1:10000 1 to 2500 Solid
10000 Lines clearly visible  
75000 Sparse, occasional lines  
100000 No hatch or one line only  

You can use solid fills at any scale to fill an enclosed area.
