Step 3: In the Select Hatch Pattern dialog box, click on the “Custom” tab to access custom patterns.Step 2: In the dialog box, click on the “Pattern” button to open the Select Hatch Pattern dialog box.Step 1: Open the Hatch and Gradient dialog box by typing “HATCH” on the command line or selecting it from the Ribbon menu.To create a custom PAT file or modify an existing one in AutoCAD: It is used to represent various materials or textures in drawings, such as bricks, tiles, grass, sand, etc. What Is a Fill Pattern?Ī fill pattern is a combination of lines and shapes that are repeated in a defined order to cover an area. It determines how the area enclosed by an object or boundary is filled with lines, dots, or other shapes. You can override the information in each field to change the way a layer standard creates a layer name by specifying layer key overrides.In AutoCAD, a PAT file is a pattern definition file that specifies the fill pattern used for hatches and fills in drawings. You can edit the layer standard definition to change these rules. (Discipline Designator) - (Major) - (Minor 1) - (Minor 2) - (Status)Ī layer in your drawing with a Discipline value of “A,” a Major value of “Wall,” a Minor 1 value of “Full,” a Minor 2 value of “Abov” and a Status value of “D,” to denote a demolition layer, would be named A-WALL-FULL-ABOV-D. Each field is separated by a hyphen (?) delimiter, as in the following example: Each part of the layer name is determined by rules specified in a corresponding field of the layer standard.įor example, the AIA 2nd Edition layer standard includes five fields that form each new layer name: Discipline Designator, Major, Minor 1, Minor 2, and Status. When you create a new layer using a layer standard, the layer name has a number of parts separated by delimiters (for example, hyphens).
