Hi Apophis,

In the one i am working on i started from a cylinder and using some boolean operation then fillet on the line selection.

Revolve will do the trick for the curvature. The bar in the wheel was made with sweep 2 rails.

This is another test i did with a plain sphere and cylinder with the boolean and fillet operation

Have you ever seen this one in Rhino http://www.toxiclab.org/tutorial.asp?ID=124

I found that Rhino3d has good tutorial for making a car. I registered on there web site (it is free) and you can download the tutorial parts. the one about the rim should help you out. http://www.rhino3d.tv/english/info/accessdenied.php

or Here http://www.carbodydesign.com/

my last test this weekend. i'm not funny with revolve. project on a surface was my favorite way - until now :-)
if i've time next week i will try further tests. ähm sorry for entering this treahd. it's not gentlemen like.
regards

Don't need to be sorry Apophis, better 1 thread of the same subject then multiple with the same subject, easier to follow.

And yes you are a gentleman, you are showing your work. :)

that is much better, did you fillet the lien around the hole for the bolt?

yes the lines around the hole for the bolts was rounded.
i've found a mistake. the outlines from the centerwheel should be rounded.
this could be a really tricky place to clean ist. :-)

Yeah you had to pointed out even for me to see it, didn't the first time. Still this is a better wheel there.

A new update, started from scratch. (yep that is me changing my mind to often, crazy stuff in there too :P)
