Thank you. I found the solution. This model is from a surface mit thickness. Y Cura will fill all areas inside the surface. After removing surface it's all fine

today I crated an Solid over a surface. Now I see my printer fills the empty area. This is made from cura in the GCODE. I think the problem is the Surface. I found no way to remove the Surface in CAD. Can I say cura he must ignore surfaces ? surf_1 is Cura, surf_2 Cura preview, surf_3 CAD and you can see the surface around the solid Thanks for help
