Need help with curved surface design (wheel)

[davisem]

Hi, i'm trying to reproduce a wheel, the last part i'm stuck on is getting the outer "tread" correct. I extruded the horizontal part "off object" so that it is shaped as the wheel, but I can't get the vertical part as the horizontal, it's just a normal straight cube. I ran out of ideas. I'll leave the link to the project and a link to the wheel i'm trying to make. Thanks!

Your model is not like the rubber tyre, which Fusion can do, but looks like you are building something else.

to finish the cross in your model, mirror the short leg.

to make one like the rubber tyre, you need to think of starting again, use Loft or Sweep tools for the raised tread.

Might help....

I'm planning to 3D print the wheel in PETG, not for professional use obviously. Why do you think I should start all over again? I printed the wheel without the raised tread and it was ok, isn't there any way I could get the vertical tread to be shaped in a uniform way as the other just using extrusion?

For your design, yes you can.  

For the rubber tyre - no it would be a loft.

Given that you have the rounded tread done, you need a sketch on the face of that part of the body - sketch the section / profile on that sketch

(will be 2 curves - projected from the tread and rim, and 2 straight lines - being the width of the tread)

extrude join that profile two directions, to the outside faces, of the rim, etc,
