Crash exporting dxf using "Symbol layer symbology"

[dario955i]

Crash.zip

What is the bug or the crash?

I'm trying exporting dxf. If I do with a small vieport size (200mx200m) everything goes well. If I try with a bigger size (2km by 2km) qgis crashes and the dxf has been created is corrupt and you cannot open.

I see that if I export a big data Qgis can have some problem, but alert on exporting, like a warning, would be better, in order to reduce the dimension. It ould be interesting unsterstand if it is issue of RAM, processor, or whatever.

Please find attached source file with data.

Steps to reproduce the issue

1. File
2. Export as dxf
3. crashes

Export as dxf

@dario955i this is with project > export > export project as DXF or with another method?

Does it happens always, regardless the project and data?

[dario955i]

Hi, yes, procedure is Project > export > export project as DXF

probably I solved choosing "Feature symbology" under symbology mode instead of "Symbol layer symbology". Now I'm able to export a very large portion of the city at the time.

In any case, in the previous mode my Qgis crashes.

@dario955i with any project/data or just a specific one? Can you attach a sample project + data that shows the issue?

[dario955i]

It crashes with this big file. If I try with small portion or other small file it doesn't. I can check layer by layer if there is one in particular causing the crash.

@dario955i thanks, then if you can attach it here.

[dario955i]

I guess my reply has not arrived to anybody because it was not “reply to all”.

I have detected one of the layer causing crash. As we are talking about data of public administration, is there any chance to send to only one recipient?

Thanks

@dario955i you should reply using Github web interface, not by replying by email to notifications.

If you cannot attach the data here you can send it to me giovanni dot manghi at gmail dot com

[gioman]

I replicated the crash with a project/data that was sent to me privately, waiting to see if we can attach them here.
