Problem: QCAD randomly crashes

Post by NPD » Wed Aug 19, 2020 1:58 pm

My QCAD installation randomly crashes and shuts down. I am editing different drawings and it doesn't seem to be related to one specific drawing. After crashing, if I wait a minute, I can re-launch the app fine. It's very annoying though. Sometimes I lose my changes. I have changed auto save to 2 min. and constantly save my drawing now.

Sometimes it will crash within 15 minutes of use. Other times I can go for an hour and before crashing. Does anyone have any idea what might be causing it? Is it a memory resource issue? I have 12 GB of RAM on my laptop. I've searched online but could not find anything recent related to random crashes.

Thanks for any help you can offer.

QCAD just crashed on me after about 2 hrs using it. I did a ctl-A to select all objects, the busy cursor displayed for a bit, then the app shut down. Is this a bug? Or am I doing something wrong?

Thanks,

Are you editing very large / complex drawings?
Can you attach / send the drawing you are working on?
Does QCAD crash (close) or does Windows indicate that the application is not responding?
What is the error / dialog of Windows in case of a crash?
Thanks.

Hi,
Select All hmmm ... or Undo!
It could serve to check for Null-entities.
How is harder, TA is the only function I know that selects them.

Attached is one of the files I was working on. It is only 38 KB in size.

QCAD just shuts down and disappears. There is no message from Windows that the app is not responding. It's really strange.

Thanks.

Thanks for the drawing.
I can't reproduce the issue with that drawing on a Win10/62. Even blowing it up to 264 KB (copying multiple times) gives me still a stable situation. Your RAM should be enough - so that can't be the reason too.

I assume something went wrong during the installation. I recommend to de-install QCAD inclusive deleting the qcad3.ini.

1. delete QCAD
2. delete qcad3.ini
3. download a installation packet which fits to your OS
4. install QCAD into a new/empty subdirectory
5. launch QCAD and test it with the same drawings which caused the problems
6. tell us how it works out ... :wink:

Work smart, not hard: QCad Pro
Win10/64, QcadPro, QcadCam version: Current.

Was this file saved from ACad > 2016? Won't open in ACad 2016 but works fine in QCAD 3.24.3.10/Win 10

Edit: what application was this file saved from?
Windows 10
