Autocad Chevron Hatch |link| May 2026

The AutoCAD Chevron Hatch is a geometric pattern commonly used in architectural and engineering drawings to represent specific materials like flooring (parquet or tile), masonry, or decorative finishes. Creating a Chevron Hatch

While standard AutoCAD hatch libraries include many patterns, a specific "Chevron" might not always be pre-installed as a single default click. You can achieve it through the following methods:

Standard Hatch Library: Check the Hatch Creation contextual tab for patterns like HERRING or ZIGZAG, which are often used as substitutes for chevron patterns.

Custom .PAT Files: You can download or create custom .pat files that define the exact chevron geometry.

Super Hatch (Express Tool): For a truly custom look, draw a single chevron "unit," turn it into a Block, and use the Super Hatch command to tile that block across an area. Key Informative Features CREATE CUSTOM CHEVRON HATCH PATTERN autocad chevron hatch

2. Chevron Pattern Definition (for a PAT file)

Save the following code as CHEVRON.PAT (plain text file) in your AutoCAD support folder (e.g., C:\Users\<YourName>\AppData\Roaming\Autodesk\AutoCAD 20xx\Rxx.x\enu\Support).

*CHEVRON, Chevron / Zigzag pattern
; Horizontal chevrons, 45° and 135° lines
0, 0,0, 0,10, 5,-5
90, 0,0, 0,10, 5,-5

Explanation:

*CHEVRON – pattern name (type this in the Hatch dialog).
0 – angle of first line family (horizontal).
0,0 – origin point.
0,10 – offset between repetitions in Y direction.
5,-5 – dash length (5 units drawn, 5 units gap). This creates the “up” stroke of the chevron.
90 – second family at 90° (vertical).
Same offsets and dash lengths produce the “down” stroke, completing the V shape.

Advanced Techniques: Dynamic Blocks with Chevron Hatch

For designers who use hatches frequently, creating a Dynamic Block of a chevron-filled rectangle is a massive time saver.

How to build it:

Draw a rectangle (e.g., 10x10 units).
Apply your custom Chevron hatch (Scale 2, Angle 45).
Select the rectangle and hatch, type BLOCK > Name it "Chevron_Tile".
Open the Block Editor (BEDIT).
Add Linear Parameters (Width, Height).
Add Scale Actions or Stretch Actions to the hatch.
Critical Step: In Properties, set the Hatch to "Associative" and "Annotative" off. Set the "Scale" of the hatch to be relative to 1.
Save the block.

Now, you can drag a corner of the block, and the chevron pattern will automatically stretch without distorting the V-shape (provided you use arrays rather than pure stretch for the hatch area).

Custom Chevron Definition

Save the following code as CHEVRON.pat in your support folder (e.g., C:\Users\<YourName>\AppData\Roaming\Autodesk\AutoCAD 20xx\Rxx.x\enu\Support).

*CHEVRON, Continuous chevron / herringbone
; Pattern spacing = 1 unit repeat
; Each chevron = two lines: 45° up/right, 45° up/left
0, 0,0, 0,0.5, 0.7071,-0.7071
0, 0.5,0, 0,0.5, 0.7071,-0.7071
90, 0,0, 0,0.5, 0.7071,-0.7071
90, 0.5,0, 0,0.5, 0.7071,-0.7071

Explanation:

0 → angle of hatch line (0° = horizontal/vertical? No – here 0° means line direction)
0,0 → start point
0,0.5 → offset between rows
0.7071,-0.7071 → dash length (0.7071) then gap (-0.7071) – creates a continuous diagonal segment.

Actually, the cleanest and easiest custom chevron pattern is: The AutoCAD Chevron Hatch is a geometric pattern

*CHEVRONS,Standard 45° chevron shape
; Horizontal period = 1, vertical period = 0.5
45, 0,0, 0,0.5, 0.3536,-0.3536
135, 0.25,0, 0,0.5, 0.3536,-0.3536

Meaning:

First line: 45° angle, starts at 0,0. Dash length 0.3536, gap 0.3536. Shift between lines 0 in X, 0.5 in Y.
Second line: 135° angle (other leg of chevron), offset by 0.25 in X so they meet.

This gives a perfect alternating V.

Introduction

Chevron hatches (V‑shaped repeating patterns) are widely used in architectural sections, geotechnical drawings, roofing details, and material callouts. AutoCAD provides chevron‑like patterns natively, but with a few tricks you can create precise, scalable, and custom chevron hatches.

2. Creating a Custom Chevron Hatch

AutoCAD uses a simple text‑based definition for hatches stored in .pat files. Here is a true chevron pattern (angle up left, angle up right, repeated horizontally and vertically). Explanation:

3. "Hatch Boundary Not Closed"

Problem: AutoCAD refuses to draw the chevron because it cannot find an island. Solution: Use PEDIT (Polyline Edit) on your boundary lines. Join all line segments into a single Polyline. Alternatively, use the BOUNDARY command to create a region, then hatch that region.
