Part of the model doesn't get printed

Hi I created a 3d model using fusion 360 and when I slice it in Simplify3d, half of it disappears. The image of the preview mode is here:

I also attached the factory file.

The image of the object is:

I wanted to note that Cura does slice it , so I don't really know why Simplify3d can't. Thanks for your help

The shape file has a number of issues that S3D is not able to cope with. I've run the model through 3DBuilder and it now slices correctly.

Attached is the repaired shape file

Thanks a lot for your help.
Can you share what can I do so that next time I don't face this same issue?

If you're in a pinch, you may be able to remedy it by selecting "Separate Connected Surfaces" from the Mesh menu after adding the model. That often allows improper meshes to print successfully.

Did you create the object from scratch in F360 or did you insert a mesh and then modify it? I've never had slicing issues with anything I've created from scratch and exported as an STL.

I created from scratch in f360.
I tried “Separate Connected Surfaces” but it jus froze the app.
