areas within surfaces are filled

[kaga 0]

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

We can't tell from these screenshots if there's something wrong with the model, or with your settings.

It could be that you have the "Remove all holes" setting enabled. Or your model could be non-manifold. If it is the latter, you could try loading your model into 3d Builder. If it tells you that "one or more models are invalidly defined", let it repair your model and export a new version.

 

If you want to know for sure what is going wrong, attach a Cura project file so we can have a look.

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
