Now I will not start critic Carlson software but from what I seen , it
offer very limited oppotunities.

It's because of the Carlson program's limit of 3 stations plus stem and
transom (calls them "bulkheads") to define the hull that I used the Blue
Peter program first. The Carlson program does insert two points on each
chine between stations for smoothing which can be done on these points
with a mouse pointer but that's still rough. For plotting it prints out
points at 8 frames which the user may locate. No doubt more points allow
for better definition of the hull, especially for larger hulls which are
on a larger scale.

But -- but this is simply to bad, you need more points than that for
develobing and plotting , ------- maby as defination points for a
spline or smoothened surface on a screen ,but less than halve Inch.
between the points shuld be the least quality for generating mesh
entities.
Realy the trick have been done since 3D surfaced ; guess unfolding
single curved surfaces been an option from the start ,but just
software that make a to rough mesh been the trouble. Only problem
with the software I used is, that the entity you can make in AutoCAD
is not avaible unless an application produce the entity ------ the
command is there and will produce a multi row single curved mesh but
you simply can not reach it without the application you need to make
or find , beside unfolding work only, when points is distribuated the
way the unfolding software expect. So producing a reasoable unfolding
rutine in AutoCAD also requier an application that produce the mesh
entity the right way. -------- Realy I thought somthing better was
avaible ; I know Rhino will not unfold entities imported from AutoCAD
but it shuld be able to unfold entities produced inside the program,
maby Im't wrong I never realy needed others than my own software.

P.C.
