I went to print a new effector for my He3d K200 so I had a spare to try to create a new blower type part cooling duct, and when the print finished , I could see through it in one line across the part. I used Simplify 3d 4.0. Up to now, it had performed flawlessly on the few prints I made. Looking at the slicing later by layer, you can see that it creates rectangle where none really exists. I have a side by side comparison of S3D on the left, and Cura 2.7 on the right. You can see the continuous seam top to bottom. Does anyone know what settings I can change that will change the slicing behavior?

Top Layer - You can see the rectangle exists in S3D, but not Cura

Mid layer, you can see the seam continue (layer 25 of 40 )

First Layer, you can see that it starts at the very bottom.

Thoughts?
