HPLINETYPE system variable
Hatch pattern linetype
Specifies the display of non-continuous linetypes for hatch patterns.
When turned off, lines in the hatch pattern display as continuous, even if a non-continuous linetype is applied to the hatch entity. When turned on, lines in the hatch pattern display with the linetype that’s applied to the hatch entity. This is not recommended because it can impact performance. Instead, you can choose a hatch pattern that is predefined with a non-continuous linetype.
Off (0): Don’t apply non-continuous linetypes to hatch entities
On (1): Apply non-continuous linetypes to hatch entities
