Actually I want to set different color for crosshatch in drawing sectioned view. The color of the hatching should be different from component edge & dimension extension line colors. And I want to set it as default color in my drawing templates.
The default color for x-hatching is always letter color - I don't think this can be changed (of course you can change the letter color, but this is probably not the point)
You can save x-hatch patterns (with line style) to disk and retrieve them from there, but they cannot be set as a default for a drawing (template).
What you can do however, is associate different cross hatching with material files - see CS32616
