Problem

A fairly simple looking wheel

But with only a profile view to start with and with rotated instances in the horizon, I knew that modeling this wheel could be troublesome if I was not careful early on.

Process

The "Extend" tool to the rescue

Despite modeling with good theoretical edges, I never would have guessed on my own that the extend tool was capable of keeping continuity to form the corner blends at the outer edge of the wheel.

Outcome

No radial array tool in Alias

Having to copy and create four extra copies of the section was an unnecessary step. I don't trust instances to keep perfect continuity so I wish Alias had a radial array tool that kept construction history.
