OK thanks.

it was not my intention to spam but I don't really know how to report this problem but I also pointed out that this was not happening in version 2.83 vertices are merged automatically.
OK I create the report for non-mainfold meshes if someone hasn't done this already.

@Sebastian Parborg (zeddb) But this happen also in the 2.93. and the problem is related to boolean issue that make error?
Why you closed this?
How I can report this problem generated by error and this is also solved for blender 2.93.6 LTS?

I did a test both with and without collections, but on Blender 2.8 it works because the boolean operations do the automatic merge of the vertices which no longer happens with Blender 2.93 and blender 3.0, I do not know the reason but this is the problem that it no longer allows you to run booleans without having meshes getting corrupted, now I will probably be told it should work like that, but this didn't happen before so all the problems are related for this part of the code that has changed.

I did follow the steps as described.

Now checked with CTRL+A > Visual Geometry to Mesh on second cube and I can reproduce some issue. Not sure if this can be resolved by backporting 10fb5cc58d21. I got confused by seeing audaspace in backtrace.

Hi I also tried disabling the sound from the preferences and I also tried with another Linux distribution on a USB stick with PuppyLinux Fossa 20.04 LTS, and with both I have the same problem of anomalous crash below the new reports obtained from these crashes of the two different Ubuntu linux operating systems with the same hardware.

I have now done a test and it also reports me that the operation cannot be performed, so I have removed the double vertices (187) and the command is executed successfully, so I consider the problem solved and Blender no longer crashes.
Anyway with Blender 2.8 it's works well without warning.

ok I will try but with blender 2.8 works well!

I'm saying that the invalid geometry generated by the boolean modifier is an other issue.
You reported that blender crashed when quadriflow was used on bad meshes with zero length edges.

I've added a check so the operator does not run on meshes with zero edge length edges now.
So the issue for this ticket is fixed and now closed.

I've tested now with blender-3.0.0-alpha+master.e79e86018e38 and it's crash this is the file made with Blender 3.0 the other for 2.83lts has a different boolean object when the one for the 3.0 has an object made by boolean union.

Did you try the latest 3.0 version?

For me applying the modifiers doesn't not create zero length edges in master.

But what do you say this is a crash problem which originated from a file where I applied the modifiers and then tried to use the remesh command, it's not another problem it's a problem with Blender 3.0

In the first I applied the modifiers with Blender 3.0 and in the second I imported the scene in Blender 2.83, and I applied the modifiers and I ran the command remesh, this means that in Blender 3.0 and in Blender 2.93 when you apply the modifiers both generate a corrupted mesh is .
You can try because I attached the original file from which I imported the scene from 3.0 to test with Blender 2.83LST, I don't know what the problem is but it is not that one has to remodel or redo the objects it is evident that there is a problem.

On Blender 2.83LST it works fine, the problem is in 293.lts and in Blender version 3.0

Below the attached file with two objects to do the tests and it works as seen from the video screen.

Hi the original model is this but with no boolean modifiers applied.

I did remove double vertices and nothing was removed, because I was in shading mode sorry for that.

I don't know how to reproduce it, I modeled the object directly in Blender using a plane.



yes, now the vertices have been moved with the command, however I can solve the problem with this command, which can be added between the options something similar in the option and to fix the mesh with this type of problem, an option like: solve The vertices with NaN value in the positions?

Sorry for the wrong information, I checked the source file and it was made with version 2.80 or something similar because the last save date is 16 Sep 2020 and I used the collections, I think it's possible that it was done with 2.83 LTS

Please change the status and don't make it as Closed, Archived!

But how? 
this is not a bug, if I have two distinct groups of vertices and I assign each a different thickness for the group of vertices the modifier should be selective and take into consideration only the vertices of the group and nothing else, but be serious about saying that this isn't that a bug?

I also add the report of the problem that I made previously to the developers of the add-on to export in glTF format

By exporting this model in PLY format I can correct the problem by easily deleting the corrupted vertices, I have also attached the PLY file exported with uv mapping if it can be useful, I have only deleted the vertices outside the model, and so I could correct the problem easily.

Here is a video always with the same plans but with a different error, if the modifiers are reversed in the order it changes, even if I first create a group and then another, every time the result changes, then I send a new video with some other test.

I don't think this is however, something that should happen, being an empty object, it is implied that it is not a mesh object, and for this reason it should not be taken into account by the modifier, this is also useful for organizing arrays and offset auxiliary objects.

I believe that this however should not be closed or archived but better evaluated.


Thank you

Wow thanks for that, if it was possible can be an awesome thing, that will be an extraordinary game changer combined with bézier development if we can have the same scale with in SVG export.

Sorry for the report I've tested many times, with different options in the morning I've used normalized options and is what I've usually do for this task, and I'm pretty sure it didn't worked, checked now, after I have saved and it's working, better than previous. the PDF works very well but the SVG has a scale out strange, but is editable.

@Paolo Furani (pafurijaz) Thanks for testing with 2.93.0 . Closing the report because it is resolved for you.

Thanks again for the report. Make sure to follow Bug Reporting guidelines to submit a good bug report onwards :)

OK thanks, for now but I hope there is a solutions in some how in the future.

This file F9908120, with latest build, now freezes OS, any solutions before release on May 26?

With this version now works Blender version: 2.93.0 Beta, branch: master, commit date: 2021-05-17 22:30, hash: rBea11b4e10ce0

Please take a look here @YimingWu (NicksBest) and @Sebastian Parborg (zeddb)

KNOWN ISSUE https://developer.blender.org/T76759

I forgot an info, the blend file has also a scene with the SGV file imported inside as a reference with all Blender icons,

Hi here the file with the various icons and other experiment, someone are in mesh but I can make the conversion into Bezier if needed, for the conversion from Blender curve into clean SVG i suggest to use this add-on, is the only for now can export blender curve into nice SVG https://github.com/leomoon-studios/leomoon-bezier2svg/tree/master/src

Hi, I did other things and small updates, and I also downloaded the original icons in SVG format, I no longer received comments on this, and I also read last week on the Forum Devtalk, this: "Matias comment the icon idea could work, but don’t like the icon final look, we need an artist that take care of this. " And I thought you were doing work independently.
But I have every thing to share as Blender File and SVG.
If you give a directions I can make somethings on this and I'm glad to help.
Greetings

This are a change according you're idea and with straight edges and other one irregular.

Yes that is a optimal idea the option with a cube but a tiny icon is harder to recognize and make for me.. anyway I have here the file for SVG and the source bender file.

I've made this now..

Hi I have an other file with the same problem, this seem to me a problem related to adaptive modifiers but I really don't know why, this has only a line-art modifier on a simple mesh lines for the measures and also this don't works please before release the final version, resolve this bug, because this at the end save a corrupted file and that was impossible to reopen because goes in continuous bug crash, and the file is impossible to recovers with Blender 2.93. I successful opened on time but the thing is not replicable, and I don't understand why.

Hi on Linux and in my Notebook seem not working, here the screenshot

Hi i saw an other similar bug reported about exporting Grease Pencil, and I used in this file an orthogonal camera, to get a 2D draft, here is the other bug. https://developer.blender.org/T86942

Worked on the latest build :) version: 2.83 (sub 13), branch: master, commit date: 2020-04-16 15:38, hash: 8cb10c124efe, type: Release
build date: 2020-04-16, 23:02:18

I had the same bug. here my terminal output when I try to open a file, but I don't find the core dump file on tmp dir, only the recovery blender quit.blend

no I tried right now and it's still not working..

Even this issue seem resolved in the build of 19/01/2019

The subdivision modifier for beveled curves also does not work.

I had some info from an other user...
From the (wip) release notes : Note however there are still some missing features in the new implementation, particularly: ... Vertex creases support (to mark vertices as sharp or semi-sharp) ... We plan to added these improvements in the 2.8 series.

Now It's works and open a new floating window with 3D editor view.

Now It's works and open a new floating window with 3D editor view.

Now work.. after restart PC and Blender.. I don't konw why, Blender in my laptop crash often.. and this make me crazy.

@Brecht Van Lommel (brecht) Thanks, now everything is ok after I changed the selection method.
