Shaping the bottom of pet soda bottles can sometimes be challenging.
Here we present two possible types of bottoms for this type of bottle.

This is part of a series of tutorials we made some time ago.

1. Step 1: The Typical One

   • First we want to credit Paul Salvator, considered by many as aSW Guru, for his model. Please visit his website (http://www.zxys.com/swparts/).
   • 
   •

2. Step 2: Preliminary Sketches..

   

   

   
   

   
   

   
   

   
   

3. Step 3: Some needed planes

   • Fives lugs in the bottom means we need some auxiliary planes.

   
   

   
   

4. Step 4: Basic Sketches (3)

   We are going to Loft and for that we need 3 Sk's in total. Two equals separated by 72°, for the end profiles. And one in the middle for the mid profile.

   

   

   
   

   
   

   
   

5. Step 5: Surfacing

   

   
   

   
   

6. Step 6: Finishing de Bottom

   

   Thicken the surface to create a solid with the proper thickness. (Around 0.4 to 0.6 mm)

   And we finished the first bottom style.

   
   

   
   

7. Step 7: The Other Bottom Style

   • This one is made using pure solids...

   
   

   
   

8. Step 8: Base Solid.

   

   Converting to Splines is optional. Just only for advanced designers who need solids with smoother curves. Your Pick!

   
   

9. Step 9: Modeling the side low reliefs

   

   

   
   

   
   

   
   

   
   

10. Step 10: Combining and Shelling

    

    
    

    
    

11. Step 11: Final Result.

    

    
    

    
    

12. Step 12: Final Words.

    Hope to be of help.
