4.2.219 Fill_area

A Fill_area is a bounded area containing colouring, hatching, or tiling.

NOTE A Fill_area communicates some aspect of a physical part characteristic or distinguishes it from its surroundings.

EXAMPLE Figure 31 depicts some fill area styles.

A Fill_area is a type of Annotation_element.

Each Fill_area may be an Associated_fill_area.

The data associated with a Fill_area are the following:

4.2.219.1 boundary

The boundary specifies the set of curves bounding a particular fill area. The resulting loop shall be closed and shall not self-intersect and it shall be planar.

See fill_area to annotation_curve for the application assertion.

4.2.219.2 reference_point

The reference_point specifies a point within the fill area, used in the placement and initiation of the fill area appearance. The reference point is a point through that a line of a hatching pattern shall pass or at which the origin of a tile shall be located. The reference point also establishes the point at which the first visible segment of a line font used as the curve appearance for a hatching pattern starts.

The reference_point need not be specified for a particular Fill_area.
