Need help: compute centerline through a 3D model

I wonder, for example, where is the centerline of this model?
Where this model start and where is the end?
On what basis would anyone generate a centerline? How many of centerlines are there? Which ones are you talking about?

Are you talking about Ruby API or SDK?

The API is there, but I don’t think there’s a method like “create_a_centerline_of_model”. You need to define more precisely what you want.. and create your own method.

Do you think it is something like this: Hobby mihai.s - #462 by mihai.s
