some ideas for add-ones to transfer dwg to dxf and print cad

[chibai]

We can actually make full use of AutoCad accoreconsole.exe to do something that is original?authentic？
Here's the code if you can get it~

code transfer dwg to dxf with computer installed AutoCad

def transfer_dwg2dxf_if_necessary(input_path: str) -> None:
    if input_path.endswith('.dwg'):
        input_dxf_path = input_path.replace('.dwg', '.dxf')
        if os.path.exists(input_dxf_path):
            os.remove(input_dxf_path)
        # create script save dwg file to dxf file by accoreconsole
        lock.acquire()
        with open(save2dxf_script_path, 'w') as f:
            f.write('AUDIT\n')
            f.write('Y\n')
            f.write('SAVE ' + input_dxf_path + '\n')
            f.write('16\n')
            f.write('QUIT\n')
        #cmd_line = 'accoreconsole.exe /i "' + input_path + '" /s "' + save2dxf_script_path + '"'
        s = time.time()
        result = subprocess.run(["accoreconsole.exe", "/i", input_path, "/s", save2dxf_script_path], stdout=subprocess.PIPE)
        e = time.time()
        lock.release()
        if result.returncode  != 0:
            print('fail to transfer from dwg 2 dxf')
            return False
        print("transfer time", e - s)
        return input_dxf_path
    else:
        return input_path

code print CAD file with computer installed AutoCad, while '2048SQUARE' is predefined papersize

def pt2str(pt: Tuple[float, float]) -> str:
    return str(round(pt[0], 2)) + ',' + str(round(pt[1], 2))

def print_png(input_path, output_path: str, ext: BoundingBox) -> None:
    lock.acquire()
    with open(cad2png_script_path, 'w') as f:
        # Command:
        f.write('FILEDIA\n')
        # Enter new value for FILEDIA <1>:
        f.write('0\n')
        # USC command
        f.write('UCS\n')
        # Word coordinate
        f.write('W\n')
        # Command:
        f.write('-PLOT\n')
        # Detailed plot configuration? [Yes/No] <No>:
        f.write('Y\n')
        # Enter a layout name or [?] <Model>:
        f.write('Model\n')
        # Enter an output device name or [?] <None>:
        f.write('PublishToWeb PNG.pc3\n')
        # Enter paper size or [?] <ANSI A (11.00 x 8.50 Inches)>
        f.write('2048SQUARE\n')
        # Enter drawing orientation [Portrait/Landscape] <Portrait>
        f.write('P\n')
        # Plot upside down? [Yes/No] <No>
        f.write('N\n')
        # Enter plot area [Display/Extents/Limits/View/Window] <Display>
        f.write('W\n')
        # 输入窗口的左下角 <0.000000,0.000000>
        f.write(pt2str(ext.extmin) + '\n')
        # 输入窗口的右上角 <0.000000,0.000000>
        f.write(pt2str(ext.extmax) + '\n')
        # Enter plot scale (Plotted Inches=Drawing Units) or [Fit] <Fit>
        f.write('F\n')
        # Enter plot offset (x,y) or [Center] <0.00,0.00>
        f.write('C\n')
        # Plot with plot styles? [Yes/No] <Yes>:
        f.write('Y\n')
        # Enter plot style table name or [?] (enter . for none) <>:
        f.write('.\n')
        # Plot with lineweights? [Yes/No] <Yes>
        f.write('Y\n')
        # Enter shade plot setting [As displayed/legacy Wireframe/legacy Hidden/Visualstyles/Rendered] <As displayed>:
        f.write('A\n')
        # Enter file name <>:
        f.write('"' + output_path + '"\n')
        # Save changes to page setup? [Yes/No]
        f.write('N\n')
        # Proceed with plot [Yes/No] <Y>
        f.write('Y\n')
        # quit the command
        f.write('QUIT\n')
        f.write('Y\n')
    s = time.time()
    #cmd_line = 'accoreconsole.exe /i "' + input_path + '" /s "' + cad2png_script_path + '"'
    result = subprocess.run(["accoreconsole.exe", "/i", input_path, "/s", cad2png_script_path], stdout=subprocess.PIPE)
    e = time.time()
    lock.release()
    if result.returncode  != 0:
        print('fail to print image')
    print('print image: ', e - s)

These codes are actually running in our startup company web software online, but our starup failed, so I come to share the idea.
We can actually make full use AutoCad accoreconsole.exe to do something

[mozman]

I googled "accoreconsole.exe" and found that it also ships with DWG TrueView 2019 and later. So, at least for Windows users, it is possible to get this application for free. I will consider a similar addon as for ODAFC if it works on my machine.

[mozman]

I tested this simple script to convert a DWG to a DXF:

AUDIT
Y
SAVE "C:\Users\mozman\Desktop\Now\ezdxf\acconsole\output.dxf"
16
QUIT

Execution by accoreconsole.exe , where<fullpath> is a placeholder to shorten the text:
accoreconsole.exe /i "<fullpath>\input.dwg" /s "<fullpath>\script.scr"

and got this result:

Redirect stdout (file: C:\Users\mozman\AppData\Local\Temp\accc152842).

Enter BACKSPACE to interrupt script.



AUDIT
Unknown command "AUDIT".  Press F1 for help.

It doesn't also recognize the commands SAVE or HELP. I assume a full AutoCAD license is required to execute scripts.

[chibai]

That's wired, Here's some result for my AutoCad accoreconsole
accoreconsole.exe -help

C:\Users\chibai>accoreconsole.exe -help

try "accoreconsole.exe /i "\input.dwg"
And try AUDIT or SAVE within accoreconsole CMD

[mozman]

The console does not accept any input, just beeps...

I assume the accoreconsole.exe just opens the console of the application and passes the script and the DWG TrueView console does not accept any input, it just shows some status messages at the console.

[chibai]

OK, my idea only work for AutoCad Licensen then..

I will not add an add-on to wrap the accoreconsole despite the fact that this add-on would be similar to the ODAFC add-on, but there are some differences:

• The ODA FileConverter is accessible to everyone for free of Windows, macOS and Linux.
• I can maintain the ODAFC add-on, because I have access to the application.
• The ODAFC has an impractical command line interface that is hidden by the add-on, that was the main reason to include this add-on in ezdxf. There is only a thematic relationship between the ODAFC and ezdxf, but the add-on could also be a standalone Python package.
• Your script shows that the usage of the accoreconsole is straight forward for experienced AutoCAD users, and if they can use a search-engine they may find this discussion thread 😄

[chibai]

Agree~!

I saw the ODA official website. The ODA FileConverter is 'Free Trail'? I'm not sure it is free or not?

[mozman]

The converter is free, the trail is for the ODA membership. Just click on "Try for Free".

that's cool!thanks!
