Bonjour,
Je cherche à replier ce modèle 2D sur lui même (obtenir un tube de diamètre 58mm) avec SketchupWeb, est-ce possible selon vous ?
Je suis relativement débutant et ne maîtrise pas encore toutes les subtilités du logiciel 
Merci pour votre aide !
Without the aid of plugins, my first thought is to take advantage of the faceted nature of circles in SketchUp. If the circle has 24 facets, say, select the left edge, copy-duplicate it to the right edge, and then array (type 24/ in the VCB) 24 copies in between and let those lines break the raw geometry into faces. Then incrementally use the rotate tool to fold them into place.
That would rely on the math being perfect between the faceted circumference of your circle and the width of your flattened face.
I agree with @RTCool. Dividing the vertical surface equally and then rotating sections of it would get you there from where you are starting.
What is it that you are actually trying to model? There’s likely a better way but it would require a different starting point.
Merci pour l’aide ! J’essaie de dessiner un support à canette avec une découpe sur le devant.
Translated by Google:
Is this for 3D printing? If so, you’ll have a difficult time in SketchUp Free converting that to a printable volume.
Instead you could create the can holder without the cutout. Then create the shape of the cutout and use Intersect Faces to intersect the two. Erase what isn’t needed leaving the holder with the cutout.
Much much quicker ! Which software did you use ? I know Sketchup Web might be a bit limited
I set this up in SketchUp 2026 (Desktop) but it’s exactly the same in SketchUp Free.
SketchUp Web is limited in the fact that you can’t use extensions and there are some extensions that could make this a little faster but you can do all of this with native tools, anyway.
Are you doing this as a hobby?
I just started 3d design this morning, ordered a 3d printer last week (Bambu PS1). Still looking for the right software to use for personal use. Good that the community can help
It would be a good thing to learn to use SketchUp’s tools and you can do that in the free version but maybe be open to the idea of switching to the desktop version if you find you need more capability.
If you want to see some example, I modeled everything shown here in SketchUp for 3D printing.
FWIW, this is one way of dealing with your shape using extensions. I made the flat shape I was rotating in my first screen shot into a 3D volume and rounded the edges of the cutout. Then used an extension to bend it into the can shape. To be honest it’s not the way I would go about modeling this particular thing but it’s onr way to get there.
depending on the level of detail you want / need, you could even rely on pushpull only for this shape. it won’t be nicely rounded, but it does the job.
I’ll learn with Sketchup web version, and might switch later. Thank you for the explanations, I see now more clearly how to design it (I didn’t know intersect function so far).
Thank you for the sharing. I’ll try it too !
