Hi,

i trying to do a mesh around a domain of a city. this can be easily done with snappy function.

But in order to make the mesh better, I though of adding layers. At the moment, the layers are weird in the sense that it stop at those sharp edges.

Is there anyway to avoid this?

Attached is a picture of the different layer effect. The one on the right is what i am aiming for. Any idea how to get to that?

Hi,

Increasing the featureAngle entry (which located at sub-dictionary of controls for layer addition) to 130 may work.

Hi,

It will be easier to identify the problem, if you can upload your test case.
