Grab a face and push or pull it, extruding or extending. PushPull speeds up modeling by using curves to add or remove volumes from existing surfaces.

Try It

  1. Download Rhino 8 Evaluation for Windows or Mac.
  2. Download and open the PushPull-Demo.3dm model.
  3. Run the PushPull command: You are prompted to select a surface. Select any of the surfaces on the icosahedron.
  4. Move the mouse to extrude the surface, but do not click or complete the command. In the command options, notice that you are in Extrude mode.
  5. In the Command Options, change the Mode to Extend.
  6. Move the mouse to extend the surface face away from (or into) the center of the face. Click to complete the command. Notice how you can quickly modify the entire solid polysurface.
  7. Try this on your own surfaces. Please ask questions and give feedback on the Discourse Forum.
