@fredo6 I also want to suggest that after using the plug-in, the components do not deform, bend in shape and retain their component properties. This will give more options to the users of your plugin. As an example, I additionally created objects made using the Flowify plugin. It transfers components without distortion, but the components lose their connection to each other, if you can implement this in your plugin, it will be great.
Test.skp - This is the model you asked for

the triangulating line that appears after using the plugin should become soft+smooth

Nope.
It should be soft = true; smooth = true AND cast shadows = false otherwise it will not work.

I agree +20 on this!
I already said that in the original discussion on Trimble forum and I 100% stand on that.
Slicing should be optional. The default behavior should be "deform only", that would make more sense.

@fredo6 said:

I am not sure it is possible to identfy and carry over the quad mesh, because of the slicing.

I guess it's super-difficult when you need to slice (so you are creating new geometry with new vertex-order/face-IDs), but it's actually quite easy when you just need to deform.
The key is that you apply preemptive triangulation (with different properties for planar quads/planar n-gons) at the very beginning of the deforming operation in order to stabilize vertex order, edge properties and UV mapping, then you can safely preserve/restore everything once the deformation is done.

I'm not a programmer, but I managed to formalize the whole algorithm decently enough that Claude can execute that brilliantly (based on the steps that I use to do manually in order to stabilize a mesh for proper Subdivision/Uv-mapping workflow).

I achieved good deformations which are reliably preserving quads, and UV mapping with decent fallback methods for n-gons.
I was planning to share the code with you regardless (for review before publishing it on Sketchucation), I think it could be interesting if you could integrate (and probably improve) it in some of your plugins, this one could be a clear candidate.

Нет.
Должно быть soft = true; smooth = true И cast shadows = false, иначе это не сработает.

I was sure that I was not giving complete information, but I wrote that I knew)) I think Fredo knows exactly what it's about and how it should be. But still, thanks for the correction, maybe this way we will get the desired result faster)

Я планировал поделиться с вами кодом в любом случае (для проверки перед публикацией на Sketchucation), думаю, было бы интересно, если бы вы интегрировали (и, возможно, улучшили) его в некоторые из ваших плагинов, этот может стать подходящим вариантом.

I would like to ask you to share this interesting plugin. I created a lot of interesting things myself with the help of Claude. It's interesting to see what others are doing.

fredo6

With FredoBend v1.2b, you can normally keep the quad properties by turning off:

Slicing
remove coplanar edge
soften edges

Here is a video showing the process.

FredoBends - Quads.mp4

Here is the test file. Tell me if this is OK.

I don't understand what you mean.

The component / group property is kept. If you bend a component. the output is a component. Same for subcomponents.

However, all the content of the container is made unique, because bending is not a transformation but a creation of geometry. This has nothing to do with slicing.

Wow, I realize that I didn't understand correctly the proposal, so I retreat my + 20 on this.
Because you basically can't do that in Sketchup (you'd need some sort of modifier system similar to the 3dsMax one to accomplish this).
I understood that he was talking about a non-slicing behavior instead (which would be preferable).

It's currently in the last (I hope so) alpha stage, I'll need to fix a couple of edge cases before it can go beta.

@fredo6 said:

Я не понимаю, что вы имеете в виду.

Свойство компонента/группы сохраняется. Если вы изгибаете компонент, на выходе получается компонент. То же самое относится и к подкомпонентам.

Однако всё содержимое контейнера уникально, поскольку изгибание — это не трансформация, а создание геометрии. Это не имеет ничего общего с разрезанием.

Perhaps I did not state my thought correctly, perhaps I got confused in the terms, or perhaps my translator did not translate it correctly) I want to say the following: when we use a plugin, is it possible not to deform the component so that the component does not lose its connection with its own kind? As an example in the video, I used the Copy Along Curve plugin. He arranged the components in an arc without deforming or making the components unique.

3.mp4

fredo6

Plugins like Copy Along Curve just move and rotate the objects to position them along the curve. So, this is not really bending and it is another use case.

For FredoBend, it is possible to add an option where only the top container is modified, leaving the sub-container not deformed.

alexpacio2013

It doesn't work for me. With my sketchup 2025 full of plugins, it doesn't work. In practice, if I place the object on a line or a curve, it doesn't get curved. While if I install it on sketchup 2026 with very few plugins, it works. There are some incompatibilities, but it doesn't give me any errors. Anyway, congratulations, it's fantastic.

If there are errors in the Ruby Console you should post those to help Fredo determine the cause.

I presume you have an updated LibFredo installed.

alexpacio2013

@Rich-O-Brien Latest version of FredoBend 1.2b and FredoLib 15.9a. Everything is up to date.

Looks great Fredo. This is destructive one, isn't it? No way to edit afterwards

Для FredoBend можно добавить опцию, при которой изменяется только верхний контейнер , а подконтейнер остается недеформированным.

I think that's what you need. At least it would be great to experience it. Thank you.

mx_constructtools

It looks like the plugin mx_constructtools is redefining a base method (Array#sum), which is not a good practice and is dangerous for other plugins. This is causing the error.

The bent object is of course new geometry.

However, as shown in the main video:

the original object is untouched
If you modify this original object, you can update the bent object in one click.
you can also edit the bent object and change the bending parameters. If the original object has been modified, the new bent object will be updated.
there is an option to save a copy of the original object to an external file. This is for the case where you delete the original object in the model, including its definition.
