About Modifying Cross-Hatching
The default line style for cross sections is leader style and default color of the hatch pattern is blue. You can modify the cross-hatching in planar and offset cross sections.
Cross-hatch cosmetics are independent of orientation. Your spacing specifications are stored in model coordinates, while angles are measured from the horizontal of the current view. The latter is designed to retain the same angle of cross hatching when the model is retrieved in a drawing cross-sectional view.
Modifying the cross-hatching in Part or Assembly mode does not update any existing drawing views.
