Thank you Michael.
yes, tweaking the shape through control points will work definitely better.
Thanks for your input.
Very much appreciate it.
Enjoying MOI very much.
Also, in my last project I had a similar shape and builted a ring around it...
Basically, at end of project I had an area underneath that did not closed (somehow though, it did boolean union OK....).
As I grow these models as RPs, I have discovered Netfab basic (STL viewr + repair) and that software took care of that little area.
So, basically I am squared.

Thank you Michael.
