Import Linesplan DXF to FREESHIP?

[internetturk]

Hi everybody,
i have a linesplan in DXF format.
I have to scale it and want to import FREESHIP.
How can i make?
How can i import offset or linesplan (in DXF format) to FREESHIP?
Thanks a lot

I don't think you can, but why would you want to anyways?
You should read the manual that should have come with it, but I think you can import a text file that has the curves in it.

i have a linesplan and i have to scale it's Lbp 50 m to 65 m.
How can i scale?
I think may be FREESHIP can...
Do you offer me any software for scale ship? (Lbp, B,D,T and CB)

[Raggi_Thor]

You can scale a dxf in BricsCad or IntelliCad.
www.bricscad.com

This software create a offset table?
It's a marine software?

[Raggi_Thor]

No, it's a general cad program.
It simply scales the lines.
To scale an offset table you could use Excel or OpenOffice maybe?

[internetturk]

It's not help to me
Only ship or marine software can scale(Lbp, B, D and CB)

[Raggi_Thor]

I am sorry, I didn't quite understand what you want :-)
Lbp, length between perpendiculars?
CB, center of buyoance?

If the linesplan is a dxf ddrawin, I would just scale it to be 65m :-)

[internetturk]

you can but how to redraw frame sections?
How to calculate CB or LCB...
but Marine software make it.

[Raggi_Thor]

Yes, I agree. FreeShip or RhinoMarine for example.
IN the old days a boatbuilder would scale the the frame spacing also, so the frames remained the same. LCB should be in the same relative position if you only scale the length.

There are so many possiblities,
you could import a lines plan into freeship or rhino and the model a new hull close to the existing lines, then scale an make new sections.

Ok how to import linesplan FREESHIP?
How can make existing hull in FREESHIP?

This is from the FreeShip user manual, page 17!

3.5.4 Surface.
Import a textfile containing a number of 3D curves. This
option can best be used when the offsets of a round
bottomed hull need to be imported. These curves may
have any number of points which may differ from curve to
curve. Usually the curves run from the bottom of the hull
upwards, however longitudinal curves are allowed too,
just as long as all the curves have the same orientation
and run in the same direction. It is important that the
curves are not crossing each other.
The user will be prompted how many points in
longitudinal direction (number of columns) and in
vertical direction (number of rows) the imported
hull must have. Then the program fits a B-Spline
surface through these points such that the new
surface interpolates these points.
The first line of the file must either be a 0 (zero) or a 1. A zero indicates that all coordinates are in
meters while a one indicates that the coordinates are in feet. Each curve is defined by a sequence
of X,Y and Z coordinates separated by at least 1 space. The end of a curve is indicated by an
empty line after the last coordinate. The last line in the file should be 'EOF'. The following is an
example of a file containing 3 stations.

Here's another possibility, convert the body plan to jpg or bmp and load it as a background. Then make a hull.
