Why does Preview show top of model cut off?

[rw3iss]

Hi,
I'm experiencing an issue with Simplify3D cutting off part of the top of the model. I'm attaching the full model view, and what shows in the preview.
Why would it cut the top off like this?
My print settings seem correct. Build area dimensions are correct. The model geometry should be correct, pretty simple.
Any ideas?

Check the Advanced tab to make sure you don't have the "stop printing at height" option enabled.

If the part gets very thin at the top, you may also want to check your thin wall settings (see the article below)

Another possible cause of a similar-looking effect is that Simplify3D may have the View > Cross Section feature turned on.
