<![CDATA[Transform a 2D rectangle to a L shape]]>Hello,
i have an interrogation for build a special shape. What method is the best for :
Transform a 2D rectangle to a L shape. It's a simple folding to X position.

If you have an idea.

Thanks

j'ai bien réussi à créer cette forme avec les "paths / expand / offset".
mais cela me pose beaucoup de problèmes pour la suite, à savoir, le positionnement des perçages. En effet c'est compliqué car l'angle de pliage peut varier en fonction des utilisateurs.

J'ai trouvé une fonction OPENSCAD qui effectue exactement ce que je souhaite. Est-il possible de mettre cela en place sur JSCAD

Je n'arrive pas bien à comprendre la logique de son code qui est "en vrac" dans la description de la vidéo.

Je vous remercie pour le temps que vous consacrerez à ma demande.

You won't be able to precisely mimic the bending of steel plates. Maybe

You can use offset to create a round bend. First, create a path for the L, then offset the path to create rounded corners. And finally, extrude linearly to create the plate.

Please experiment. I think that you can find an answer.

There are other ways as well, so let us know if you need more help.

By the way, we have many members so please us you favorite language.

First of all thank you for taking the time to answer me.
I'm coming back to you because I still can't model my shape. The goal is to allow people to model metal brackets. I start with a rectangle that I want to fold. The bend is therefore rounded. So I can't use 2 rectangle and apply a rotation on one of them because the folding will be straight

Do you have a design to start from ?
