Maxsurf: Problem with Trimesh Generated by Markers

[Frik]

Hi

I am new using the Maxsurf tool and new to modeling in general. I am trying to make a tug hull to a specific water line. The error happens when I generate Trimesh using Markers, It's "converging" to a point where the "split" happens.
I also noticed that the stern and bow were done wrong,

Thanks in advance for the answers, I'm lost here.

I found out what I did wrong. I did not select the "Half" button that causes the Body Plan to be halfway down the boat when it is in the markers step, if not select ends up getting that X in Trimesh.

I have exactly the same problem with a trimesh file creating an X towards the back sections of the model. . Could you explain where the 'half' button is please? Many thanks!
