Hi Pilou,

> Why they are not equal spaced as it's along a straight line?

I'm not sure of the precise reason in this case. In general filleting involves intersection between offset surfaces which is often a tolerance and adaptive based computation itself.

During that offset process, certain areas happened to get fit closer to the ideal result than others, resulting in fewer points in some areas.

It is not always easy for the algorithms to understand that a simple result can be possible especially when the surfaces involved are general curved surfaces and not primitives like cylinders or spheres.


If you need to get the most simple fillet construction possible, you may be able to get better results with a solid modeler like SolidWorks or something like that. They have generally spent more time making special case handling for more types of situations.
