Delftship to maxsurf . . . How to ?

Hi, forum newbie here.

Reading this forum for decades now and never registered.
After a lot of hours playing around with FREEship and later Delftship I would
like to export my work and import it in Maxsurf.

Can anyone point me in the right direction here ?

Thanks

 

Hi H50,

IGES is probably the most convenient format in which to transfer a model from Freeship to most surface-based modellers.

Freeship, and the pro versions of Delftship, can export IGES surfaces that most 3D CAD programs can import and use.

 

Not very easy, because they do not use the same mathematical surface representation. Freeship uses subdivision surface, maxsurf uses NURBS. (Freeship can use triangular surface , Maxsuf cannot.)

You can go thru IGES import/xport. But freeship will first translate its subdivision surface into a bunch of small NURB surface that will approximate the subdivision surface. You will get in Maxsurf (or rhino) a bunch of surfaces with a bunch of control points, even if you have a simple surface with few control points in Freeship.

 

have 3.2 free here, you'r meaning old freeship and Delfship 3.2 PRO exports igis?
ah, didnt know that, still post my question couse i dont know what a VIZ block is
delftship 3.2 free polylines into max gives me a VIZ block, what is a VIZ block?
it extrudes in a vertical way and turns to nurb but not it into a surface
btw, how you check deadrise? with a geotriangle off a printout or what?

good old freeship indeed exports IGIS, thx marshmat, i forgot about that and try
stil wondering on that deadrise and what a VIZ block is and how to handle it..

 

Just tested Freeship to Maxsurf with the FS tug sample and it seems to go through fine via IGES. (see attached) As mentioned above, the triangular corners may be broken up into a few small surfaces but these are pretty easy to delete and correct.

 

Even if you transfer via iges you wont have the control point net in Maxsurf to do any further work. Might be better to export an offsets table, bring them into Maxusrf as markers and create a new surface model in Maxsurf using the markers as references.

 

No, actually via IGES you do get the full surface and its control point net which can then be modified in the normal way.

 

Sorry I should have been clearer. I should have said wont have a clean control point net.

I did an iges export of thier 2nd demo file and it said 278 surfaces exported so I expect that while MS would import all of them, the model would be a nightmare to work with and modify.

 

Quite right. The tug model was OK but others may well have an unmanageable number of surfaces.

 

It depends on the number of triangular surfaces, or the number of surface with more than 4 points. These are not supported by NURBS and have to be converted to multiple patches.

 

thanks Martijn i didnt know that or forgot about nurb properties
like taking the inflatable mesh of when converting to editable mesh
polylines should be to close i read somewhere, maybe even to surfaces
so much to do so litle time the rabbit said asking for half a cup
stations on in delftship comes nicely over in 3dmax, maxsurf academic now and still to try
3d adobe reviewer can take the mesh out and select polylines
a well, a little extra study may help, and forget about viz blocks eh

 

hmm... background pic only in delftship and not in freeship, no tricks?
after having mis-tryd re-installing acrobat pro extended 3d trial with one sour eye
now jugling free/delft, has anybody seen a pot of gold that makes live easy'r ?

 

drawing over a background img -only in delft- to export to free -that only exports igis witch free delft dont
was reading freeship to delftship and delftship to freeship and ok parts works one way using the steps in this link
but to export from free to export igis greys out, running free, delft and pro demo now, only peeking at the ad on's
pro does it all and exports igis alrite (what is not visible in the pro demo) so i'm counting my blessings to buy
and stop hijacking the tread wondering how pro boats do in maxsurf's seakeeper ;-)

 

hi,
i'm azahar and i'm a student. actually i'm not so clear how to export Delftship to maxsurf.
plz help me..
