3DCoat 2025 Development

[Stefka]

Hi @Oleg Shapov

Thank you very much for your support.

Here is my original post from some time ago.

This is really a pain in the arse. Please try your best to convince the developers that the feature of "Manifold Problem" becomes optional.

Thank you and best regards

Walter

Dear Developers
I´m using version 2025.03, but my problem is related as well to all the older versions.
Hope this is the right place to talk about it!?
I´m using 3DCoat now for more than 2 years. I´m only doing hard surface modeling. One of my main problems is in the Modeling room.
It is the "non-manifold" problem.
As everybody knows, this function is deleting triangles anywhere in your model, neither showing you where the triangles have been deleted, nor giving you the chance to disable the deletion!
This unwanted deletion ruins many of my models and costs me a lot of time to repair. The non-manifold problem is not an issue for my models.
Because of the deletion, the modeling room is of no use for me, because it causes more problems than solutions. Instead, I´m using blender for this, because here I never got any complaints, nor did I ever get any parts of my model willfully deleted.

PLEASE!
1. Make the correction of any non-manifold problem optional in your software. User may disable this option and never again gets patronized. I think many may be greatful if you tell them that their model has some errors but nobody wants you to delete any triangles out of a 50´ - 100´ triangles and leave them a nice puzzle to solve.

2. If enabled, the places where you deleted part of the model should be marked.

3. The note that is posted, when triangles are deleted , should not be in the footer of the window. When working concentrated on something, and not expecting any messages, you will not see it. I think it´s better to place any error messages in the center of the screen.

So PLEASE again, set this function as an option.

Thank you very much for your kind attention.

Best regards
Walter

I immediately added your suggestion to the wishlist. But don't put your hopes on me because I have no more influence on developers than you do. As an assistant in this inconvenience, try the Show Open Edge tool.

Hi @Oleg Shapov

Don´t underestimate yourself, you are moderator, so your influence is much higher than mine. If you support my "wish" I´m sure it has much more weight than my "wish" alone.

Thank you, yes I know the tool. But, if you have an object with a lot of Open Edges, you get an overwhelming result. Finding the hole that came out as a result of Non-Manifold, is a problem. Picking the correct one out of a bunch of holes is an endless story. As you may know, the modelling part is its own story and I don´t use it for construction, in the time it takes me to find the correct tool in some sub-sub-sub menu I can finish the construction using my current standard tool.

The only reason I use the modelling menu is to export the selected part of a construction as a stand alone part.

Thanks for your support, best regards

Hi, in 3DCoat-2024, (surface mode) in the left panel of tools, brushes and commands there is a section called "Custom", and within that section is the "base brush".
As you can see in the image below:

That said, now in the latest build of 3DCoat-2025 I can't find the Custom section and the base brush within it.
What happened to the section and the base brush? Was this section with the base brush builder accidentally removed?
Please, could someone check this in the latest build of 3DCoat-2025?
Thank you very much.

[Carlosan]

you are right, base brush is gone :(

Maybe it's because of the switch to python. I'll check today.

You are right! Thank you very much for checking this.

Bugs encountered in Modeling room:

1. Undo (Ctrl+Z) not working properly:

   • To revert an action, I often have to press Ctrl+Z multiple times instead of just once.

2. Symmetry tool issues:

   • After performing an action, symmetry fails to replicate it on the opposite side.

   • Even when adding equally spaced edges on both sides, moving one side does not update symmetrically on the other.

3. Visual reference:

   • I’ve attached a GIF demonstrating these bugs for better clarity.

Symmetry tool issues:

Please disable "Virtual Mirror Mode", it is still buggy. And then apply symmetry "Apply Symmetry to All Layers" after all manipulations.

Thanks for the message, I found the bug and fixed it. The build with the fix will be available today or tomorrow.

Thanks Oleg, yes it's buggy but apply symmerry works well!

Did you have the oportunity to test the Ctrl+Z issue? If you need a new video I can record It, because It's driving me crazy, in live smooth It happens all the time and if It is disabled is the same but it happens after some actions like extrude.

Yes, I updated the task about this bug. I hope the developer will hear us. Спасибо!

This is a case of Subdivide.
I have already fixed 3 crashes with Smart Hybrid.
Maybe this has already been fixed.
Wait for build 07
