How to Use Hatch Command in AutoCAD
Step 1: Activate Hatch Command

You can type HATCH or simply H in the command line and press Enter.
-
Or go to Home Tab → Draw Panel → Hatch.
Step 2: Select Hatch Pattern
-
In the Hatch Creation tab, choose the type of fill:
-
Pattern (like ANSI31 for section lines, AR-BRSTD for brick, AR-CONC for concrete, etc.)
-
Solid Fill (for coloring an area).
-
Gradient Fill (for smooth color shading).
-
Step 3: Pick Internal Point or Boundary
-
Pick Internal Point: Click inside a closed area to hatch automatically.
-
Select Boundary: Choose specific objects (lines, circles, polylines) as boundary.
Step 4: Adjust Hatch Settings
-
Scale → Controls size of pattern (increase if hatch looks dense).
-
Angle → Rotates the pattern.
-
Associative Hatch → If ON, hatch updates automatically when boundary changes.
Step 5: Finish
-
Press Enter or click Close Hatch Creation Tab.
