Polygon Anomalies?

When I want to put a polygon and then make a mound, I notice that what I have is not in equation with the photo examples that I see in Devmode.
I find myself - by making a polygon - with the 3 arrows (blue, red, green) outside the polygon and not inside the polygon!
While on Polygon Objects we can clearly see that the 3 arrows (blue, red, green) are indeed inside the polygon!
On the attached screen we can clearly see that the 3 blue, red and green arrows are well outside the polygon!

The centroid of an irregular concave polygon is often outside the polygon.

Thanks !

In this case, how should I proceed to make a mound ?

Grab the green arrow and move that up,

And adjust terraforming distance if needed

Thanks !

follow the recommended procedure, but I have not mastered it ! I have more of a spectacular fall than a mound !

Did you enlarge the terraforming falloff?
