Thanks for your help. Sorry for gaps. It was my bad selection. I`ve uploaded my 3d model from which I took that edge.

I`ve attached image. Left is imported, right is manually created (points are in same places as vertex).
I`ve thought there is some way to convert that polylines to curve line to have points in place of vertices.

If I would convert edges to curves in that way then it should be easy to rebuild subd model in nurbs faster.
I don`t want to rebuild curve. I want to have my line points in place of my vertices. I would like to automate process a bit to not redraw every line from subd mesh.

post the original wings in .obj format

the original obj seems to be build with quads

it could be converted with smooth curves ... maybe ;)

this ?

in ' Draw curve ' choose ' Trough points '

pick the points on your draw ... and all will be made with smooth lines

fantastic tool ! ;)

That`s how I created this (right curve). I used that line tool manually but If I have 1000 lines like this to rebuild whole subd model then it will took ages and I may make mistakes often.

I`m asking about automatic way of doing this on 1000 curves. Next I would rebuild surfaces from those curves in MoI3d.

If 3dm file would be a text file then I could write python script to change that polyline curve to nurbs curve with same vertex->points position.
I know there is scriptingin MoI3d but I don`t know it :)

example with ' through point ' command ( in yellow )

pick points on your sketch or object and the curve is made ... right click to end

go to top view to be sure your curve is flat ... on an object ( if you draw in front view ) you can hasardously pick on points that are not in the same plan

use manipulator around your curve and move a corner ... you'll see the word ' Flat ' when all the points are in the same plan

( not sure my english is orthodox !!! ;)

ok you want ALL the lines to simulate feathers ...

? !!! , ,? .)

post the original obj .. to experiment Subd

I don`t get it. Where is that command "through points"? There is no such a command in "commands" folder.

Here you have 3 feathers in OBJ (made for subd presentation)

select your object and click 'Subdiv' command

looking for the links

Through points is in Draw curve - Free form

fantastic scripts of Max Smirnov !!

install all the pack 'Subdiv ' ... split scale bridge

and enjoy ;)

Subdiv_beta9
sBridge.v.0.71.2015.03.26
sScale.v.0.6.2015.03.28
sSplit.v.0.95.2015.08.10

unzip and all files in your MoI3d commands folder

you can also install if not Custom UI

a bunch of useful stuff and you'll see Subdiv and the others in the bottom bar of MoI

The delCorners script, (of Max), may be helpful.

3 obj subd

internal error when i upload the 3dm file ( size ? ) so i zip the guy ;

yes ... a polyline ... and a click on the script ' Delcorners ' ...

another great tool ;)

And here some infos about modeling inside Moi with the Max Subdive scripts! ;)

mmmmm ! mon topic favori !!! ;)

et on croise les doigts pour que, dans une future version de MoI, il y ait genre les outils ' Edit subdivision de Formz ' ou un ' Tspline ' mais en mieux ;)

Thanks guys, that DelCorners on curves and Subdiv on small patches (between hard edges) is a King!

I`ve created model without extra loops on hard edges (obj). Next in MoI3d I divided it to patches. Next I used subdivide script. In few places I failed but it`s a nice method.

It`s still to long for me but it`s possible to do is nome way.

you can also play with Blend Nsided Loft to generate round surface between curves

place the different curves on Z axes higher or lower ... to various results

( curves are better when you use a script called Rebuild ...( another great tool ) ( need joined segments or curves .... then Rebuild )
