How to Make a 3D Model of the One Ring in Inventor

Ever wanted to create a 3D-model of the one ring, with the correct measurements as seen hanging on the neck of Frodo Baggins in the Lord of the Rings movies? Well, start reading already!

Steps

1. Press the new part (mm) and start up a new sketch. From here, make lines with measurements as seen on the image.
   
   
   
   
   
   
   


2. Exit out of the Line/Rectangle tool. Now, delete every measurement on the sketch.
   
   
   
   
   
   
   


3. Select the Circle tool. Make a circle, having the center-point on top of the line to the very right. Make sure the edge of the circle touches the middle of the left side of the rectangle.
   
   
   
   
   
   
   


4. Use the Trim tool (X) to remove lines. Do this until you are left with what is seen on the image.
   
   
   
   
   
   
   


5. Re-add the length to the line seen on the image. Do this using the Dimensions tool.
   
   
   
   
   
   
   


6. Press Finish Sketch and press the Revolve tool. For "Profile", select the area shown on the image.
   
   
   
   
   
   
   


7. Press the Axis button and select the line to the very right. Then hit OK.
   
   
   
   
   
   
   


8. Select the two outer-edges of the ring. Hold Shift while pressing them. Press the little rounded edge button (Fillet) that appears and select 2 mm as the value.
   
   
   
   
   
   
   


9. Do the same for the two inner-edges, but select 1 mm as the value.
   
   
   
   
   
   
   


10. 
    
    
    
    Change the material to Gold and the appearance to "Metal 1800F Hot".

Tips

• 10,35 mm is the radius that the ring has, as seen on the neck of Frodo in the films. By going to the sketch and changing the 10.35 mm line, you can now easily change the size of the ring.
