Hatches can be applied to 2D planar and screen objects and walls (wall hatches are only visible in Top/Plan view).
There are two types of hatches: associative and non-associative. The appearance of both types of hatches are determined by hatch pattern definitions.
Associative hatch fills are resources. You can apply existing resources from the Attributes palette, and then map the resource to suit a specific object, if needed. Use the Resource Manager to create and apply resources; see Resource Manager.
There are two ways to customize the hatch to suit the object to which it is applied; use either the Fill Hatch Settings button in the Attributes palette, or use the Attribute Mapping tool to move, rotate, or scale the hatch (see Mapping Hatch and Tile Fills).
Associative hatches can be specified as a default class attribute (see Setting Class Properties).
Non-associative hatches are placed on objects or areas of the drawing with the Hatch command. They obtain most of their attributes from hatch pattern definitions, but they do not use the color definitions for the lines that make up the hatch. Non-associative hatches obtain the color definitions from the current default attributes. They do not use any background definitions, and therefore have no background color. A non-associative hatch is similar to a screen that displays over other objects; the spaces between the lines are empty, and display portions of any objects behind the hatch.
Non-associative hatches are placed inside an area that is defined by selected objects or lines. The start point of the hatch is set with the Hatch command. Unlike associative hatches, non-associative hatches can be moved to another area or object. However, unless the new area is the same shape and size as the previous one, the pattern will not fit.
Non-associative hatches are groups that are not associated with an object. They do not rotate with the object or act like a fill. They can be broken down into their individual elements with the Ungroup command. For a non-associative hatch to become part of an object, it must be grouped with the object.
