Why is Cura not slicing the opening in my model and is ignoring it.

My model has a recess in it but Cura keeps slicing it as a box shape.  I've added images.

Hey @hafeez8,

 

Welcome to the Ultimaker Community 🚀

That doesn't look good 😦

 

Do you have a project file for us so we can help troubleshoot?
To save a project file go to File -> Save project.

make sure the setting 'remove all holes' is not checked, in the mesh fixes section.

obewan unchecking remove all holes did not work, but thank you.   I've uploaded my project file Mari.

@hafeez8 the model has errors .  I was able to repair the model using the Mesh Tools plugin and the Fix Normals command.  MS 3D Builder is more capable and would also repair it.

The model on the left has been repaired by 3D Builder.

If you are using Blender or TinkerCad you should always check the models for errors.
