Hi all,
I updated to the latest Simply3D and since tried to reslice a model I've printed before with no problems. Now when I prepare to print, some of the model goes away. I can't figure out how to stop the slicer from doing this. It's basically a model with support structure in the model itself, so no support needs to be added to the model for printing. I can get S3D to add support no problem, but the model's own support seems a bit better on the final product. Previous version of S3D didn't do this.

After print prep
Here's the model itself.
