Here's another method for making the back of an iPhone:

First of all, draw one quarter of the top top profile with the freehand curve tool. Having it be a single curve instead of using fillets will create a surface that's easier to work with later on.


Then, draw an arc in a side view. This will create the chrome ring on the iPhone.


Sweep the arc along the curve we created in the beginning.


Mirror the surface until you have the complete ring. Once that's done, join the surfaces together.


Now, use the new Nsided command to create the dome.


Adjust the dome bulge parameter to size, and you're done! For this example, I set the dome bulge to 0.25.

Nice one DonPedro,


Michael, are you still looking at getting the other curvature options into n-sided?

Hi Burr,

> Michael, are you still looking at getting the other curvature options into n-sided?

It's on my "todo" list but it's not what I'm actively working on at the moment...

It may be difficult to get that to be G2, I'm mainly hoping still for g1 for it but trying to improve the shaping so it doesn't tend to sort of stack up tighter changes near the boundaries so much.
