Problems with model export geometry

Hallo liebes WUFI Team,

Because the model I need to build is an elliptical gym, I tried to build the elliptical model in Rhino (a modeling software) (Figure 1).

Then convert the surfaces in the model into a mesh and import it into Sketch up (Figure 2), and then perform the related operations (Figure 3)

However, after importing WUFI PLUS from Sketch up, I found that the part that should belong to the same component has become multiple components (Figure 4).

What can I do to solve this problem, or what is the problem with the process? Is there a problem with the mesh conversion step? Because there is no such problem with the square model(Figure 5). So can you tell me if there is another way to convert a surface to a mesh?

Thank you very much
