# Tissue add-on courses

> **PAACADEMY offers online courses teaching the Tissue add-on for Blender, enabling computational designers to generate complex parametric tessellations and structured geometries for digital fabrication.**

Tissue is a Blender add-on for tessellation and generative modeling, applying repeating patterns or complex geometric subdivisions to mesh surfaces. Its core tessellation function maps a component geometry onto each face of a base mesh, producing complex parametric surface treatments from simple mesh topology. In fabrication contexts, this makes Tissue highly applicable to generating structured surface geometries.

At PAACADEMY, Tissue is integrated into _Parametric Workflows with Blender_ by Luis Pacheco. It provides a robust, free alternative to Rhino/Grasshopper paneling logic:

- **Surface Tessellation:** Instantly populating architectural facades or complex meshes with custom 3D modules.
- **Dual Meshes:** Converting standard mesh topologies into complex dual meshes for unique structural and aesthetic expressions.
- **Fabrication Toolpath Prep:** Generating the intricate, repeating geometries required for 3D printing, CNC milling, and robotic toolpaths natively within Blender.

## FAQ

### What is Tissue for Blender and how is it used in parametric design?

Tissue is a Blender add-on for tessellation and generative modeling that maps component geometries onto mesh faces to produce complex parametric surface treatments. In fabrication contexts, it generates structured surface geometries for 3D printing, CNC milling and robotic toolpaths. At PAACADEMY, it is taught in _Parametric Workflows with Blender_ by Luis Pacheco, an 8-hour beginner course on Geometry Nodes and fabrication toolpath generation.

### What does Parametric Workflows with Blender: Animating Robots for Digital Fabrication cover?

_Parametric Workflows with Blender_ by Luis Pacheco is an 8-hour beginner course across 18 lessons covering: developing toolpaths for 3D printers, CNC machines and robotic arms using Blender and Geometry Nodes; harnessing Geometry Nodes for parametric design; and utilizing Blender's attribute system to customize toolpaths based on design conditions.

### How does Blender compare to Grasshopper for parametric fabrication design at PAACADEMY?

Grasshopper is a visual programming environment embedded in Rhino, widely used in architecture for parametric modeling and simulation. Blender's Geometry Nodes is a comparable node-based parametric system with the advantage of free access and integrated animation tools for robot motion simulation. At PAACADEMY, _Parametric Workflows with Blender_ provides a Blender-native path to fabrication toolpath design that does not require a Rhino license.
