How do I use push/pull to create 3D bodies?

You can create 3D bodies from faces and closed 2D sketches by pushing or pulling the faces and sketch fillings. 

1. Select a closed sketch’s filling or a face.
   
   
2. There are two ways to create 3D bodies:
   a. Drag the arrows to pull or push the sketch or face.
   
   b. Directly type in the exact length of extrusion and press the Return key to finalize the dimension. 
   
   
   
3. Deselect the body by selecting the empty space or Deselect all. 

When you’re pushing or pulling, you’re actually doing the same thing as these actions:

• Extrude
  
  From a closed sketch or a face with no adjacent fillets or chamfers, you can use the push or pull action to extrude your selected shape. 
• Offset with adjacent fillets
  
  If there’s a fillet on at least one of your edges, pushing or pulling the face will offset your body in a way that keeps the rate of the offset and extrudes all other parts. 
• Create holes from closed sketches
  
  If you create a closed sketch on a face, and select and pull it, you can create a hole in your body. 
• Modify holes or cylinders
  
  Select the non-planar face of the hole and pull it. You’ll notice that its radius changes as you pull.
