[BUG] Crash on leaving sketch after converting to mesh about cad_sketcher HOT 11 CLOSED

Could you share the content of the console after the crash?

You'll have to start blender from the console in order to see the console after the crash...

from cad_sketcher.

I toggled console with Windows > Toggle system console command.

Then I added a sketch with a rectangle and a circle, and left sketch without converting them into mesh.
But the console command did not register any activities at all.

Then I edited the sketch, and converted the sketch to mesh.
Again, no change in the log.

As soon as I leave the sketch, BforArtists crashes along with the console.
So I do not see anything captured in it.

After the crash, I found this file:
C:\Users<userName>\AppData\Local\Temp\CAD_Sketcher-main-Nagesh.log

(unlike the help description, the file name contains "-main-Nagesh" for some reason.)
There is no other log file with "CAD_sketcher" in its name anywhere on my laptop.
(I checked with Everywhere, which indexes all files.)

But the log file does not have any content at all. (It has 0 bytes size).

Finally, I found that I have to save the file first:
So I saved the file first, and then repeated the experiment.
This time it produced a crash report at-
C:\Users<UserName>\AppData\Local\Temp<FileName>.crash.txt

This is attached.

Die you try the addon with vanilla blender?

To see the console after the crash you can start blender from a console. You should find it by tipping "cmd" in the windows search. From the console you should be enough to just enter "blender".

Yes, Blender 4.1 also crashes in an identical manner.
I launched Blender using Command Prompt.

After Blender crashed, the Command Prompt shows the following text:
(this is the entire text of the session, including installation of the addon, etc.)

Ahh i'm afraid we cannot take reports into account that apply to alpha versions. If this also happens with stable versions or when 4.1 gets into beta we can have another look.

OK. Thanks!

I tried this with Blender 4.0.2 RC and it does not crash.

Blender 4.1 is scheduled to enter the beta stage on 24th Jan 2024.
AFAICT, it won't be possible to raise this as a bug for Blender 4.1, right?

How do you mean, report it to the blender Foundation?

from cad_sketcher.

Well, when an addon works with Blender 4.0 but not with 4.1, there are two possible reasons:

1. The code of 4.1 is not backward compatible with 4.0 (so far as a given addon is concerned)
2. Code in 4.1 is broken unintentionally (regression issue).

In the first case, the addon developers have to know how the code is going to change, so that they can make the addon compatible with the new version. IINW Blender developer forum provides this information in advance to the addon developers, so that they can modify their addons concurrently.

In the second case, the user should be redirected to raise the bug in Blender's GitHub.

As a user, I don't know which case applies here.
So if you let me know, I can close the bug here, and raise it in the Blender's GitHub.

The final intent is to give an early feedback to the right group, so that the correction can be applied at the earliest.

from cad_sketcher.

It's likely the second scenario as braking changes are usually made in major releases. Reporting the bug upstream makes sense however this usually requires a simplified setup as blender developers probably don't have the time to install addons...

Good news, they fixed it already: blender/blender@ce81bdc

Great!
I use development version of bforartists, so this change will hopefully appear in next week's release!

Many thanks!
