While these details are necessary for 3D print, doing this way the file will end up much too details.

We usually use a circle of 48 divisions for this size.

So as an approximation with existing Primitives that would end up as:

Hey its a year later and I am finally getting back to this project. I'm slightly lost as to why n-fcon6 was used in the way it was. Is there some kind of calculation performed to show that I need to scale con6 by some amount to get the size I needed? 

Additionally if there is such a calculator or formula to determine what I need, then how do I used that to do the back of the wheel that is missing in the example you provided? 

Would I be better of creating 48 resolution primitives for my wheels and then just performing my original proposal?



As an aside to this, I am very interested in making some train track using a similar method where I can create the rail profiles needed and then calculate path points. When talking in circles that are in the 500mm radius range, is there a primitive set that is suggested or am I better off making segments that are 2LDU long and placing them all over?
