Maxsurf Modeler Complex Hull Form

Hello,

I am attempting to model the hull form of an anchor handler vessel, and I have been unsuccessful in my attempts. I've tried importing a DXF background but Maxsurf reads the file incorrectly, I've tried using Markers but cannot develop a surface out of them, and I've tried to draw curves, again with no luck. Is there any expert here who might be able to help me get started?
