Meshing Question - Trying to optimize my mesh.

 From:  PaQ

Hello, I hope this question wasn't yet asked, I didn't find any thread about this question (but I haven't lost a lot of time in the research).

I'm trying to understand the meshing dialog box, and I got a stange result using a simple test object.

-------------------------------


Here's my object, I put 5 in the angle option, because I really want smooth curve in the red line area.




-------------------------------



I divide larger poly than 3, so I have a more regular subdivision, something than can be usefull if I wish to paint so displacement map on it later.


-------------------------------

Now I wan't to reduce the polygon count in the fillet area, to optimize my model a little bit. There are way to many poly so I use the [Avoid smaller than] option,
and here's the result.



I don't realy understand the result, the left side of the object is ok, that's exactly the amount of polys I need ... but I don't really understand why there are still so many
polys on the fillet right side.

I have post the .3dm file also ... the object is quite simple and clear.
