Have fun trying to mesh this object
Meshing has apparently not improved in V6, and to be honnest, it is still as bad as 10 years ago.
I managed to get a clean mesh using MOI 3D.
The slider is a farce, and the so-called “detailed options” too since most parameters are utterly ignored ; in particular the aspect ratio.
Thin parts with rounded edges exibit awful creases.
The only way to get decent meshes is to make them with GH+Kangaroo, or use another software altogether.
