The feature that allows hatching or filling to be updated when its boundary objects are modified is known as Associative. This functionality links the hatch to the boundary objects, meaning any changes made to the geometry, whether it's moving, resizing, or altering the shape, will automatically update the hatch or fill pattern accordingly.

This is particularly useful in design workflows where objects are frequently adjusted, as it saves time and helps maintain accuracy. For example, if you draw a hatch within a closed polyline, the hatch will dynamically update in response to any alterations made to that polyline. This ensures that the appearance of the design remains consistent and reflective of any modifications made, enhancing overall efficiency in the drawing process.

Other types, like Independent or Non-associative, do not offer this automatic update feature, which can lead to discrepancies between the hatch and its boundary if the geometry changes. Static also implies that the hatch remains fixed regardless of the underlying boundaries, which is not desirable for dynamic drafting needs. Therefore, Associative is the correct choice for ensuring that hatching remains consistent with its boundaries in AutoCAD.
