how to create custom hatch pattern autocad

Selecting the custom tab will bring up the same dialog box with nothing in there as shown highlighted in yellow in the image on the right. Next select the ellipses as shown next to the pattern name to bring up Hatch Pattern Palette with a Custom tab shown.Īfter selecting the ellipses you will see the Hatch Pattern Palette as shown on the left portion of the image below. This will bring up the Hatch and Gradient dialog box as shown below. You are asking “Sam, what custom tab?” Select Hatch on the Ribbon (or type Hatch at the command prompt) then T for Settings. Let us now add some extra patterns to the custom tab. You can give your patterns a name with the format *MYNAME, DESCRIPTION followed by the pattern as shown below in the EARTH example.Example of the Earth You can edit the default PAT files that are installed with AutoCAD by using Notepad and adding your custom hatch pattern data at the end of the file. Hatch patterns are stored in a file named ACAD.PAT or ACADISO.PAT. Recently I have had several people ask me about the custom hatch pattern tab in AutoCAD and how to populate that tab with your custom patterns. A dash pattern is superimposed on the line.Let’s talk Hatch Pattens. A line is considered to be of infinite length.It is used only for dashed lines.ĭelta-y value indicates the spacing between members of the family that is, it is measured perpendicular to the lines. Each pattern line is considered to be the first member of a line family, created by applying the delta offsets in both directions to generate an infinite family of parallel lines.ĭelta-x value indicates the displacement between members of the family in the direction of the line.Blank lines and text to the right of a semicolon are ignored.However, you must begin a pattern definition with a letter or number, not a special character. You can include letters, numbers, and the special characters underline (_), hyphen (-), and dollar sign ($). Each line in a pattern definition can contain up to 80 characters.Hatch pattern definitions follow these rules:

This simple pattern definition specifies a line drawn at an angle of 45 degrees, the first line of the family of hatch lines is to pass through the drawing origin (0,0), and that the spacing between hatch lines of the family is to be 0.125 drawing units.
