Modeling Car Tire

Here, you will learn how to model a tire with threads. Yet another non TOTAL BEGINNER tutorial. You'll have to know some basis of Rhino. But still easy to follow.

Step 1

To begin with you will need curves like this.



Step 2

Wich you will need to mirror join and revolve.



Step 3

And that is the body of the tire. For the tread you will need several curves, and this is one of them.



Step 4

Offset that curve for 0.2 and 0.4 units.



Step 5

Then trim them like this.



Step 6

Use the Match command (curve to change - upper, curve to change - lower, and set the options in the dialog box like shown in the picture.



Step 7

Turn on control points and delete this point.



Step 8

You will need to extend that curve (extend curve command), and trim that curve because it probably will not be the same length. Copy those two curves with a 2.0 unit spacemen. Move those two curves so they are centered in perspective to the Z axis (the green line in the pic).



Step 9

You will need these curves as well.



Step 10

Offset the two in the middle by 0.1 upwards and the upper by 0.2 to the right.



Step 11

Trim all those curves and you should get something like this:



Step 12

Fillet these curves with 0.1 units.



Step 13

Join all of these curves, and you should have something like this.



Step 14

Trim the upper surface with the selected surface.



Step 15

Project the curve on the upper surface (project curve on surface).



Step 16

Duplicate the edge of the upper surface (duplicate edge).



Step 17

Trim that curve with the projected curve and join them.



Step 18

Trim the upper surface with that curve, and extrude that surface with 1.0 units.





Step 19

Array that surface in 60 copies in a 360 degree angle.



Step 20

Explode the lower surface and make a curve like this.



Step 21

Revolve that curve and join that surface with the center piece of the exploded surface.



Step 22

Make a tube witch will be the center of the tread.



Step 23

Mirror the 60 arrayed surfaces and now all you have to do is to join the tread surfaces with a Boolean command (the Boolean union will take a looooong time depending on your processor speed, the alternative is to join only a few at a time or manually trim and join everything, the fastest but it is a lot of work. Delete the surface created 3 pics earlier and join the rest of the surfaces and that is that, and it should look something like this.



We're done!

Bye!
