Maxsurf Help

Hi,
can anyone tell me why when I try to deduct skin thickness so that I can export the dxf file to CAD that not all sections seem to have the correct deduction?
On approx 20% of the section it seems to overlay the deducted section exactly on top of the original section! Some of these are towards the bow and the others towards the transom!
I was going to use the deducted sections in CAD to get the stations cut but don't want to proceed until i get this figured out.

Thanks

 

Is there a reason you aren't using moulded lines? Maxsurf can add the skin thickness in your volume/stability calculations.
