Grasshopper | Hatch

Hatch patterns are now available for your parametric models in Grasshopper.

Hatch Patterns in Grasshopper

Save time, maintain consistency, and keep your drawings flexible. Your hatches update automatically as your Grasshopper model evolves. No manual rework needed.

Library of Hatch Patterns

Grasshopper now recognizes hatch patterns already applied in your Rhino model. Use them to control direction, scale, and density directly within your parametric workflow.

Create Your Own Patterns

Build custom hatch patterns using algorithms in Grasshopper and share them across your team. You can even export them as *.pat files for use in other applications.

Import Hatch Patterns

Import Hatch Patterns: Save time by quickly and efficiently importing your existing *.pat files into Grasshopper . Share them across your team to meet any project-specific needs.

Try It

Use the Model Hatch Component to generate parametric Voronoi hatches inside a boundary curve. Adjust rotation, scale, base point, background color, and fill style to control the appearance.

  1. Download Rhino 8 Evaluation for Windows or Mac.
  2. Download and open the Voronoi2D.gh model.
  3. Download and open the definition in Grasshopper . The file contains a parametric 2D Voronoi pattern that will become a hatch pattern.
  4. In Rhino:
    1. Maximize the Top viewport.
    2. Zoom out to see the Voronoi hatch preview.
    3. Run the Circle command to use as a closed boundary curve.
    4. Select the curve.
  5. In Grasshopper:
    1. Right-click the Curve Parameter (highlighted in red) connected to the Model Hatch Component, select Set one curve.
    2. Play around with the Rotation and Scale sliders in the Model Hatch Component. See how the pattern updates in the viewport.
