You can fill an area enclosed by a line or curve with a solid color or pattern. This filled area is called a hatch. Hatches are classified into 3 types: Solid hatches filled with a solid color, pattern hatches, and user-defined pattern hatches.
An area enclosed by a line or curve is filled with a solid color.
An area enclosed by a line or curve is filled with a simple pattern. There are 53 types of predefined patterns.
The pattern and background colors can be set, but line intervals cannot be set, so displayed patterns will be fixed even when scaling on the screen or printing.
User-defined pattern hatch
An area enclosed by a line or curve is filled an uniquely-defined pattern.
User-defined patterns are classified into 2 types: those combining multiple lines, and those freely combining shapes such as lines, circles, or curves.
You can also set the transparency for solid and pattern hatches. Setting the transparency enables to display hidden shapes under a hatch.
