The outline is not closed - SOFIPLUS

Hello everybody.
I am Wilson, from Paris , new to the community and happy to be a part of it.
Currently I am working on the modeling in Sofiplus of an air cooler, I have generated 3D of the hull but when I want to assign a surface in sofiplus to the model, that puts me: the outline is not closed.
Can someone please help me? thank you for your comeback!

It is not possible to create an area that connects itself (two edges have the same line). Try to separate you model into smaller segments.
Another way to model complex structures is by using the program SOFiMSHC within the TEDDY.
We have designed a few useful examples that explain the modelling of rotated systems.
You can find them within the
