Hi
I use network to draw my model and i would like to choose the place of the seam
In my screen shot , by default, the seam is on the right but i would like on the back .
I must map (flow) a model on this bottle and i think it's easier to have the seam back
Thanks a lot.

Hi Finema, the seam is going to end up at the start/end point seam of the closed curves. Right now there isn't a tool for changing that directly but there is a kind of roundabout way. The roundabout way is to do a Loft just between your 2 closed top/bottom curves. While you are in Loft it is then possible to drag the seam points that are shown in the viewport to change the seam of the loft surface. After you have moved those to the back and finished the loft command you can delete your original curves, extract the Loft's edges using Ctrl+C/Ctrl+V and use those extracted curves for the Network.

Thanks a lot Michael, it's perfect.
My other problem now is to flow a model on this bottle
I would like the flowed model go on the shoulders of the bottle. Projection don't run for that. (see my screenshot)
and i join the 3dm file because i have tried a lot of thinks with flow but I can't finalize.
Thanks a lot

Hi Finema, for projective Flow mode the surface normals of the base surface need to all hit the target object. It can be ok if only a very small area misses but you've got too much that misses there.

But the base surface doesn't have to be a plane, it can be a curved surface something like this:



So that's something you could try. Projective mode also expects for the target to be smooth so you'd probably need to put a top cap on it and fillet the top edge if your base surface goes over that area, even if the actual object you are transforming will miss that area it still needs to be smooth if the base surface will hit it.

The other option I guess is non-projective flow.

"The other option I guess is non-projective flow."

Yes I'm trying, but I can't do it with non-projective.
it's really important for me to do this projection because it's for a work and i must do the render for monday.
Thanks again.

Another possibility might be some direct on surface drawing in the 3D view, if you place control points at fairly close intervals it will probably be close enough to the surface to be able to trim with it.

- Michael

No Michael because it's not a simple shape as in my joined file
I must flow a complex piece of Jewelwery that i have modeled in MoI.
Thanks again.

Hi Michael
"But the base surface doesn't have to be a plane, it can be a curved surface something like this:"

must i do a flow for the base and the model before projection ?

can you send an example ?


thanks a lot.

and Does anyone have a technique for mapping this shape on the shoulder?
thanks in advance

Works absolutly not for me!

I copy well the "edges" of the Loft change Points (Ellipse + Circle) and not the "closed curves" !
+ the original rounded sides
Make the Network : seam comes back in Front and not on left as during the moving point Loft!

Hi Finema!

I was interested.
Michael's method works,"you just have to slowly touch the object".
A little round at the top would be advantageous, I haven't done that yet.
And you have to push something back and forth.

Hi Finema,

I did for that case, a curve-to-curve flow from a straight line to a bent curve, as in the attached file. I didn't do it very carefully, just a demo of something to try.

Positioning your object and plane at an angle like Franz shows above seems like a good idea.

You have to move the seam point to a spot where one of the other direction curves has an endpoint.

It looks like you've moved it just by some random amount instead of having it land on a spot where the network has one of its other direction curves.

Yes that was that!
When I move points to some another previous existing intersections / "Sides curves" / Top/ Bottom that works! :)

I have believed that was a general concept! Move points anywhere you want so the seam! :)

Hi fine,
When i am having issues with base surface and target mapping, i sometimes solve it by creating a copy of my target object, then dicing and seperating a piece to be the base, then using the edit frame flat snap to get the base ready for the flow. The thing to watch for doing that is too much "fold over or bunching" when flattening the taget into a base.

I'm not in a position to demonstrate or play along right now...

A big thank you to all of you.
I will work with your solutions and come back to you to show you the result.
Thank you again!

hi
here my final work with flow
thanks to not diffuse this picture
thanks again for your help

Very nice bottle, Finema!

thanks Franz
