TdwgReader fails to open this file

Post by KKesslau_SEMA » 14 May 2019, 10:39

Hello there,

we encountered the problem that the TdwgReader fails to open/read this specific dwg-file:
https://www.heinze.de/cad-manager/18985642/0/

The file format reads as AC1014. The problem seems to lie within this file, because we can import other DWG-files with AC1014 without a problem. We converted this file to AC1027 and it worked without a problem. But not all of our costumers have for example AutoCAT LT to convert the files.
Opening the file in a viewer (i used Autodesk DWG TrueView 2016 and 2019) also works.

I debugged the import and it seems that the error occurs at

Code: Select all

TdwgReader.ReadObjects
in the Unit DWG.pas.

Can you look into it?

Thanks in advance,
Kevin

Hello Kevin,

Thank you for the file.

We could reproduce the Access Violation error when reading this file, it occurs in a TdwgDataBase.ReadSubEnts procedure (DWG.pas). I have forwarded the problem to CAD VCL development team by opening a support case.
