OBJ file in surface3d

Question

I have new problem couldnt find any solution in Google... im using a qml file and it contain a surface3d, when i show it with a obj file that was in qt examples (oilrig) it could show correct without any problems!

but when i used my own obj file (boat) it couldnt show correct in surface3d application (showing with grid Triangles, not like a volume...)

in blender(a program for editing 3d models) my boat and oilrig has correct views but in surface3d just oilrig is true, i tested 100 items more that downloaded from internet but cant work? just oilrig that was from qt examples was true can any one help me????
