Quick polymodeling rims

First you have to deside how many spokes the rim should have, i selected 6 for mine,
therefore i start with a cylinger with 12 sides. (5 spokes = 10 sides and so on, i hope you get the point)
And add 1 Cap Segment also.

pic1

Select the faces like in pic2, and + bevel them alittle.
(in edit mesh)

pic2

Then on the same faces you make a litte + extrude(localy),
and then bevel again, but this time a - bevel so it looks like in pic3.

pic3

Now you have to scale these faces on the deaph of the rim, so it looks like pic 4

pic4

Then extrude 3 times (still in local), and bevel the last like in pic5

pic5

Select the faces on the back on the spokes, and move to the front to make the spokes thiner, like pic6

pic6

Now make a circle (spline) and place it exactly in the same possition as the rim. (align)
And just extrude the faces to make it look like pic7.

pic7

Delete the selected faces and go to vertex mode. now weld the vertices so you get no holes in the mesh.

pic8

Select all the vertices you just welded, and scale then all together so they fit inside the spline-circle,
and you might have to rotare the selected vertices in pic9 so all outer faces have about the same size.

pic9

Now extrude the faces on the edges so it looks like pic10

pic10

Select the edges all way around the rim as you see on a part on pic 11

pic11

Chamfer that edge, about as much as you see in pic12.
And make sure you have the new edge infront of each spoke straight as also shown in pic12

pic12

Now make the areas shown in pic13 have different smoothinggroups
(the pic to the left have all faces on the front selected also)

pic13

Select the edge shown in pic14 and scale it out alittle to get a rounder edge into the spokes.

pic14

I made the center (as you see in pic15) by extruding scaling and beveling and rotating,
and if you made it this far i dont hink i have to write step by step for this part.
(remember to give this part a new smoothinggroup)

pic15

Now you just need to add a meshsmooth and set it to as many iterations as you need.
And mark Smoothing Groups under "seperate by".
you should now be able to render something like this.

if you dont get this to work, rtfm, DONT mail me pls! ;)
