i want an alloy wheel rim of rim diameter 431mm....any models available??
There are many wheels in the library, but most do not have a diameter called out. I'd just pick one you like, and scale it, or modify it slightly to have the desired diameter.
Scaling is the easiest option in this case as you won't need to be concerned with a feature tree. Working with simple imported geometry would work fine.
Be sure to go hit the like button: Ferrari Rim 20"
Please Prefix statements with "please", and end with "thank you". It makes text based messages much nicer to read. They then come across as requests rather than commands :)
Scaled file attached.
