Missing sections from print?

[3DEnthusiast]

Hi all!
S3D is missing entire sections from this model when I try to slice it. Cura, however, doesn't have that issue. Below, I have attached an image of what S3D is doing. What am I missing?

Thanks!

The model is...to put it mildly....not a good model. It consists of two very similar meshes that virtually duplicate each other.

Fortunately, S3D has something that will sort out this mess! Use the "Separate Connected Surfaces" option....and you'll be able to print it.

Okay,
That's just plain confusing. I tried to do that when I had everything set up on the build plate and it still errored but putting the tower by itself and doing it works fine.

Thanks!
