Can't open DXF file generated by cad.net

[AliHatam]

We use cad.net in our project and generate an output file in DXF format . But generated file doesn't open in Autodesk Autocad software . the generated file open in cad.net editor and viewer properly (Chiral.jpg) . I attach generated file for more investigation (generatedDxfFile in attachments) . That is important for us and our customers the file to be opened in Autocad
I also tested dwg output , but I have same results
We genrate this file in this way :
In summary , we read some blocks from other file (dwg file - BaseBlocks in attachments) , draw some lines and genreate some layers and generate final file

Hi,

Thank you for your mesage.

Could you please let me know the CAD .NET version that you are using?
Could you please also send me an example code (e.g. by email or PM me) that you are using to generate the file?

Hello, can you say that a mistake or a bug caused this file export error?
We want to release the first version of our software but this problem has prevented us

Hi,
This error happens because the file contains two blockrecords with the same handles, and each handle should be unique.

Hi,
Please, have a look at the all blockrecords that have same handle =C0F7.

A lot of our errors fixed by this advice
but we have some other errors. I think your help can help us to fix.

We have 3 Test file :
Test1.dwg ( In Dwgs.zip) shows normally in our software but after consume a lot of memory will not open in Autocad and system hangs.

Test2.dwg ( In Dwgs.zip) shows normally in our software but when open in Auotcad there is some errors
( Test2 - In Our Software.png , Test2 - In Autocad-Before Open.png ,Test2- In Autocad.png in Images)

Test3.dwg same as Test2.dwg

Hi,
I examined the files you sent. The Test1 - Error.dwg file wasn't created by either our software or AutoCAD and it contains errors, more precisely, it has a lot of blockrecords with the same name and handle, e.g.
BRANCH - $BF6F
GLOBEVALVE - $BF70
VPRESSUREGAGE - $BF71
...
Other files seem to have the same problem.
As a solution, you can open such files in AutoCAD and recover them. For more information about recovering files, please, refer to https://www.easeus.com/file-recovery/re ... matically.

Hi , and thanks for your answer
First , all of files was created by Cad.Net absolutely
Second , we searched more in keywords you reported us , "same handle for a lot of block records"

We faced this problem because we have a file as block repository that contains about 50 common blocks and we read and add blocks to our main project file from this file . the occurred mistake was the method we add blocks to our main file that result all similar blocks had same handle .

For persons who has this problem and mistake in future , the right way for add same block twice or more is clone blocks and described in this forum post :

Hi,
My colleague Mikhail gave an example of how to copy CADEntity. And he mentioned that this method doesn't keep the original handle value, so the developer should check the handle's uniqueness.
It means if you make a copy - you should generate new handle for this copy.

Thanks, Maria. The problem occurs when the file contains two block entries with the same descriptors, I fixed this on my side. Really helpful.
