DWG import/export memory leak (AD 2.5.7 Mac)

[Fixx]

Opening and exporting big (3 MB and bigger) DWG drawings usually eats all memory and then some. System halts and I have to force quit Designer (version 2.5.7). Please correct this behaviour.

Also, DWG export outlines/converts text to paths. This is unnecessary. Please retain editable text.

System is Mac Mini M1, 16 GB, Sonoma 14.1.1 (23B81).

Hi @Fixx,

Could you share a copy of the original file where you encountered this issue on export to DWG and confirm which export preset/settings you used? I've provided a private upload link below if you do not wish to share the file publicly.

OK I uploaded some files.

Most of the DWGs do not open in AD, one says unsupported entities, one displays weird scale/all objects are bundled together.

The one Affinity file refuses to export to DWG, uses up all memory.

The memory leak is the most severe problem. Problem is persistent and appears after file is large and complex enough -- these files are only a few of the problematic ones.

Thanks, I'd recommend exporting your .afdesign to DWG from the latest Designer 2.6 beta, as comparatively it exported in a few seconds for me without any significant memory issues, so looks like that issue has been addressed.

Equally, all the files are opening in the beta, albeit with the unusual scaling issue on some of them. I can see two unsupported entities from two of your files (AcDbOle2Frame and AcDbPdfReference in separate files). Still looking into these.

Allright, first impression is that it works for DWG i/o and is also much snappier. Thank you!

I further tested and:

text still is converted to paths on export to DWG (would be good to have option to keep it editable)

scale goes from 1:500 to 1:400 on export to DWG. Setting it to back 1:500 after does not change elements, you have to transform them manually. It did happen also in earlier version (which caused some trouble as I prepared content to wrong scale :-D). This should be corrected.
EDIT: I may be that the problem happens in IMPORT DWG as I remember I imported native DWG and got wrong scale (which I did not find out at the time). I tested exporting to DWG and importing that DWG back to AD so it is not necessarily export problem. I will check it later with Autodesk sw.

Pleased to hear that it's much improved in the 2.6 beta for you. 🙂

I've checked and this is currently by design, but feel free to post over on the feedback forums if this is something you'd like to see added.

I've logged the observed DWG import scaling issue with the developers.
