How to sculpt a nodes 3D model?

To sculpt a nodes 3D model, start with a basic mesh (e.g., cube, sphere) in software like Blender, then use sculpting brushes to shape the main form and add functional details (e.g., ports, connectors). Nodes are typically simple and functional—begin with a core shape (e.g., rounded cube for a network node). Use additive brushes (clay) for protrusions or subtractive brushes (scrape) to create connection points. For beginners, try Blender’s free tools: start with a low-poly base to keep performance smooth, and use “Dynamic Topology” to add detail only where needed.
