Please take a look at this attached STL, and the attached gcode file. Look around layer 50, at how Simplify3D sliced it, which defies common sense. There are overhangs which are meant to be solidly attached to the wall that they are attached to, yet Simplify3D sliced the file as if these are separate pieces, greatly weakening the structure. These should be integrated with the perimeters of the walls that they are attached to, not having separate perimeters. This doesn't make sense.
Granted, I'm brand new to S3D, but this just seems to defy logic.
