Unexpected entity when using dwg2dwg.bat

[yamyam]

Hello everyone,

My QCAD version is QCAD Pro 3.30.1.0, and my OS is Windows 10.

When I use dwg2dwg.bat to convert DWG format drawings to DXF format, entities that do not exist in the DWG drawings appear in the DXF drawings.

The dwg drawing is as follows:

origin.png (24.6 KiB) Viewed 73184 times

The dxf drawing is as follows:

dxf.png (30.24 KiB) Viewed 73184 times

The attached file is the dwg file with problem. Without modifying the original dwg drawing, how can I modify the .bat file or others to make the generated dxf entity consistent with the original drawing?

Opening the file with the QCAD GUI reports:

• Unsupported XData type NOT imported: 1005

Suspecting that <origin.png> is how it is opened with QCAD. (Like it did over here)
And that the original drawing looked as <dxf.png> in another CAD-application.

The additional data is probably an external reference.
See this reply or this reply.

From what you report the additional data is included in the export created by dwg2dwg.
That would mean that this command tool is capable of including external content.
Already beyond the expectations.
You did not attach such an external file, so it is impossible to test the outcome correctly.

There is no fix using the QCAD GUI for the moment, not for over 12 years now (FS#693).
You could include the external reference as a standard CAD block in the drawing file with the native application.

Remember that an external reference may use the same layer names with different attributes.
The same blocks by name with different content.
And so on ...

I presume that it is this possible duality that makes it hard to implement.

Hi, CVH

I'm sorry. I'll pay attention next time. Or is there any way to move this topic to that sub-forum?

Suspecting that <origin.png> is how it is opened with QCAD. (Like it did over here)

origin.png is the screenshot of the dwg file in my attachment opened using qcad.

And that the original drawing looked as <dxf.png> in another CAD-application.

dxf.png is the screenshot of the dwg file after I converted it to a dxf file using dwg2dwg.bat and then opened it using qcad.

I used the .bat file in the Windows CMD by typing

Code: Select all

dwg2dwg.bat -o test.dxf test.dwg

I didn't introduce any external references, and I don't understand why it generates unexpected entities

Hi,

A moderator is able to move the topic.

I can not confirm that.
- I don't have the additional content of the XREF.
- The source is a DWG and is binary.
If that was a DXF and textual then we could look for the XREF specification.

Out of curiosity: Could you attach the exported DXF file?

Hi,

I don't have the additional content of the XREF.

When I open the file test.dwg with AutoCAD, the interface is the same as <origin.png>. And when I save it as a dxf file with AutoCAD, no extra entities appear.

Out of curiosity: Could you attach the exported DXF file?

Of course, this is the dxf file generated by the .bat file.

When I open the file test.dwg with AutoCAD, the interface is the same as <origin.png>. And when I save it as a dxf file with AutoCAD, no extra entities appear.

Could it be that you opened the test.dwg file after saving it from within the QCAD GUI?
Using the GUI, the XREF is not loaded, when saved again it is no longer included.

The copy of the DWG on the forum still reports the exception.
Try to open that with AutoCAD.

I used QCAD to save test.dwg as test2.dwg.
When I opened test2.dwg, there was no Unsupported XData type NOT imported: 1005 error.
But there were still unexpected entities.

[CVH]

I used QCAD to save test.dwg as test2.dwg.

Please specify: With the QCAD GUI or with the command line tool dwg2dwg

It is starting to be a chicken-egg conversation.
What came before what? What application is used for what?

Correct me if I am wrong:
- test.dwg posted [Tue Feb 25, 2025 10:14 am] was originally created with AutoCad.
- Converted to DXF with dwg2dwg it looked like dxf.png with additional content.
- Opening the source test.dwg within the QCAD GUI looks like origin.png ... There is an exception reported, additional content not loaded.

We can't replicate the export of dwg2dwg:

Code: Select all

08:41:23: Debug:    addObject: block: "*Paper_Space"
Cannot import file: ###Obscured###QCAD/QCAD_32.1/test(org).dwg

Probably because we don't have a copy of the external reference.

Sure, this is generated using the QCAD GUI.

Correct me if I am wrong:

Yes, your understanding is completely correct. And opening the source test.dwg within the AutoCAD also looks like origin.png.
When I save test.dwg as the dxf format with AutoCAD, the result is also like origin.png.

We can't replicate the export of dwg2dwg:

Code: Select all

08:41:23: Debug:    Input file:  ###Obscured###QCAD/QCAD_32.1/test(org).dwg

08:41:23: Debug:    addObject: block: "*Paper_Space"
Cannot import file: ###Obscured###QCAD/QCAD_32.1/test(org).dwg

This is the information printed out after I converted the dwg using the command line.

Conversion finished.

Probably because we don't have a copy of the external reference.

If external reference refers to the missing information in test.dwg, then I don't actually have it. The only file I have is test.dwg.

Hi,

I can now replicate loading the DWG within the QCAD GUI and save it as DXF with the additional data.
As well with QCAD 3.32.1.0 version as with an older version 3.27.6.0

My fault before was to reopen the original.
With proper naming I did not make that mistake.
I have too many files called 'test' downloaded from the forums.


Near the end of the conversion process is another clue:

Code: Select all

08:56:21: Debug:    dynamic block ref

Block 13 and *U2 are representations of windows and how they open.
The additional data appears to be shutters ... Dynamically adjusted to both window sizes.
Something said to be unsupported.


I did encountered that before ... Searching ... Found it.
In this reply as answer to my own questions, under the second title [SOLVED]:

• This tickle down to another level of visibility, the RObject itself being set 'Invisible'.
  Supported by QCAD on load and an unknown property for QCAD users BUT also cleared while saving.

I did report something like that ... Seems to be already 5 years back: FS#2146
And that points to an open question ... Unanswered.


Bottom line: QCAD clears the invisible state of some objects.

Unfortunately, as a simple user I cannot help you any further than reporting this additionally.

Thank you, CVH, I have seen the report you submitted: https://qcad.org/bugtracker/index.php?d ... sk_id=2146

Is there any way we can increase the priority of this bug? Actually, I have encountered similar problems with many of my drawings.

[CVH]

Yes,
You can vote it up ....
For that you need to be logged on as user.
You can apply for an account, it is independent of the QCAD forum account.

Not aware that trailing reports (5 years) are looked at or that additional comment is even considered.
It won't hurt, right?
