Copier et déplacer une partie du patron pour harmoniser le tracé d'une encolure

Helichryse · December 8, 2025, 6:45pm

Bonjour, je débute sur Seamly, je suis en train de tracer mes bases de corsage et je suis un peu déconcerté sur la manière de reporter certaines parties lors qu’il faut tracer des pinces ou dans ce cas tracer l’encolure en harmonisant le point encolure/épaule sur le DEVANT et le DOS.

J’ai essayé de copier la partie encolure DVT afin de coller la première partie de l’épaule de l’épaule DEVANT/DOS afin de tracer une encolure harmonisée, mais je ne comprend pas comment réaliser cette étape. Du coup j’ai utilisé l’outil “miroir” pour dupliquer mon encolure DVT + “Déplacer” pour le coller sur l’épaule DOS, mais c’est un foutoir… Comment faites vous ? Recommandez-vous un tuto sur le sujet ?

Comme je suis nouvelle utilisatrice, je ne peux pas vous joindre de photo pour vous montrer ce que j’ai fait, je les mettrai par la suite en commentaire si je peux alors les ajouter…

Merci pour vos suggestions !

So this on what I’ve been working…

And this a test I made to manage to connect the neckline :

I would find it so much easier if their would also be a tools to make the line or point magnetic, so that would be easier to move or drop things from a place to an other.

Hello and welcome to the Seamly forum, @Helichryse

The best tool to use is the Move tool:

Before you use it, complete your neck and armhole curves & place a line from the Front High Point Shoulder (C2) o the Back High Point Shoulder (D2) (because these are the 2 points that you want to join together).

Pick up the Move tool and, while holding the CTRL/CMMD key, select the neck front point, the neck front curve, the high point shoulder point and the point at the start of the shoulder dart (C, curve, C2, P1) - make sure that they have ‘walking ants’ (dotted lines) around each one - and hit Enter. Move and rotate the selection anywhere and hit Enter again.

In the property editor box that comes up, change the Point of Origin to the point at the start of the line you created before (C2). In the Angle box, enter the angle of the line previously created (C2_D2) and in the Length box, enter the length of this same line.

In the Rotation box, enter the angle of the back shoulder slope (D2_D3) minus the front shoulder slope (C2_P1) and hit Apply to check that everything is correct. If one of the lines are going the other way, add or subtract 180°. When everything is correct, hit OK.

If your curve needs tweaking, tweak the original curves until the moved curves line up:

Here you can see a close up of my move where the 2 neck points match exactly the shoulder lines match exactly and I’ve tweaked the back neck curve so that the 2 curves run into each other with a straight line:

Repeat this process on the armholes by placing line between the 2 shoulder tip points in the direction that you want to move the points. I like to move the front onto the back.

I hope this helps you.

Oh, thank you very much @Grace sounds clear and I learned new words in english now. I’ll try it tonight ! Thank you so much !

I’m so sorry. When I saw that you replied in English, I was so happy because I would have had to translate everything with Deepl and hope for the best. It would’ve taken me half a day to describe like I did

If you right-click on the text, you can choose to translate it to French.

I finally tried it and it worked very well, not yet clear for me how to settle the degrees of the angle but I just did what you wrote and that works I can’t translate from the forum but deepl helped me a lot for my new vocabulary words. Thank you !! No worries english is perfect

I assume it is better to preserve the moved collar hidden in a group in case I have to modified again the neck in the futur, or do you erase it ? I am wondering this because I realised some line or move become impossible to erase if we keep on building on it, so I ‘m wondering if it best to keep for later (since I must still convert my basis in blouse later) or to erase them and start them over later if needed. Thank you.

I normally only draft the collars after I’ve converted the base pattern into a blouse pattern because then the neckline will be established, which will normally be wider and deeper than the original, which I draw on separately and draft the collar to the new neckline so that it will change when I change the distance from the original neckline.
