No written documentation. You have some help within the application. There are also many videos out there.

For those who are interested in CapCut, here is the link to a great guide for those who are just getting started. CapCut User Guide Hope you find it an interesting guide. It has a lot of information about the toolbars in the application.

It works fine in SU2026 for me. The box is a component in this case. [image: 1779799408521-bm.gif]

Unfortunately your EXTG and PROP groups are very very complex, and have many faces and edges that are almost coincident. The native Solids Subtract tool will let you take one from the other, BUT the results are made non-solid, with 0.0 volume. Because CutNfill relies on these tools, that is why you can't get meaningful results. SketchUp's built-in tolerance is 1/1000" and any edges that would be shorter that that are ignored, as if their end/start points are coincidental, but the tiny gap is not 'healed'. Consequently, any faces relying on such missing tiny edges will fail to form, and the result is a non-solid group with 0.0 volume. So you need to make your modeling much simpler and ensure that this tiny geometry issue is sidestepped. In real life cut and fill is not an exact science on site, so any approximation does not need to be perfect.

I use Spacely AI extension (https://www.spacely.ai/), it works pretty great and they have free trial credits too. I would recommend realistic render tool, it has a built-in preset that you can click and choose. Also, they have point & edit tool which allow you to change some part of the render without having to change the 3D model.

Version 4.5.6b - 05.25.2026 Enabled presets for stairs. [image: 1779764885301-wall_su1145_800.jpg]

Works great! [image: 1779717534197-3612e21d-ae57-431a-bfd2-3baf4d4b17c8-image.jpeg]

Killer result

I wrote an answer to your mail box

@huynhminhtriet You can see at my site https://moiscript.weebly.com/ Divers / Manuels / Sauce Tomate(Su) / SimFonia / ... 6 items But i doubt that links are always available! You can try http://www.simfonia.fr/SAT/ at https://archive.org/ your best luck! I will see on my own archives but i doubt, it was a some difficult program!

Currious I see it without any problem! https://youtu.be/9677AxsqL5A

@mamoodoo said: I do have to learn to be better organized and be orderly as you said The model I uploaded has as few polygons are possible (given your initial shape). I included plenty of steps and comments on the process. There are a couple of thing that you could learn from that process. The less unnecessary polygons you use, the better. Order of operation matters. Keep your model as modular and low poly as possible before doing the heavy deformations. Add thickness and join modules later on. When you have a big problem, don't try to one-shot at it. Divide it into multiple more manageable problems instead. I hope that can be helpful.

@Rich-O-Brien Yeah that'd be nice. It seems to look and feel a lot like their old 123D app. I hope they add some sort of texture ability.

Thank you too

Which extension are you referring to? All of them? Are you Mac or Windows?
