Meshing issues

When I create a mesh in Rhino. After designing the obejct, I am unable to generate the mesh I wish to. I have attached here 2 files - the mesh Rhino generates and the mesh which I want. How to resolve this issue? Please help me. I am a beginner in Rhino. I am using Rhino 5.


Try replacing the top and bottom flat surfaces with surface made using Loft from the perimeters to center points. The Cen OSnap may help in locating the point. The new surfaces will have “polar” isocurves. Meshing tends to follow isocurves.

In the Mesh command go to Detailed Controls and adjust the Maximum edge length.
