CHINE

[CYD]

The command create a chine  for me don't work properly.
I have problems  to create a real chine  on the surface  with a discountinuity , do you have any suggest ?

This should work.  Did you know that when you first make it you will not see a chine discontinuity - the hull remains smooth.  What you will see is that it adds an extra row and too each side are two rows that with the third define a straight part in the columns of the grid.  If you now, for example, select the middle points of the after few columns in these groups and drag them outward, you will then see a hard chine, that resolves into a smooth hull forward.  Pretty cool...

CAUTION: if you move any of these, also forward in the smooth hull, you will create discontinuities that, as far as I know, you can not get rid of, so I suggest you use this chine generator in draft hulls, and then only at the end of processing your final hull.
