Howto sideload remote DXF/DWG from URL

[schoeller]

Dear all,

thanks for PyRx.
I would like to sideload a remote (preferably) DXF file and process. Alternatively the file is downloaded, converted and then loaded. Side loading a DWG [is documented](https://github.com/CEXT-Dan/PyRx/blob/1370f3b0627e5f45d3eb46506b0580f94b4b5a27/PySamples/testSideDatabase.py) in the sample section.

I would start out like:

import urllib.request
from pyrx_imp import Rx, Ge, Gi, Db, Ap, Ed, Cv
target_url = "https://github.com/mozman/ezdxf/raw/refs/heads/master/tests/test_01_dxf_entities/houses_of_parliament_georeferenced.dxf"
data = urllib.request.urlopen(target_url)

When doing

import requests
import io
from pyrx_imp import Rx, Ge, Gi, Db, Ap, Ed, Cv
target_url = "https://github.com/CEXT-Dan/PyRx/blob/1370f3b0627e5f45d3eb46506b0580f94b4b5a27/unitTests/testmedia/BCADCIVIL1.dwg"
data = requests.get(target_url)
inmemoryfile = io.BytesIO(data.content)
sideDb = Db.Database(inmemoryfile, True)
sideDb.closeInput(True)
inmemoryfile.close()

I receive

: PYLOAD
PyErr Python argument types in
    Database.__init__(Database, _io.BytesIO, bool)
did not match C++ signature:
    __init__(struct _object * __ptr64, bool, bool)
    __init__(struct _object * __ptr64)
    __init__(struct _object * __ptr64) ,Traceback -

For now there seems to be no other option than saving to a temporary file. However, you need to use the Db.dxfIn(dxf_file) or Db.readDwgFile(dwg_file) method.

import tempfile
import traceback
from pathlib import Path

import requests
from pyrx_imp import Db


def PyRxCmd_doit():
    try:
        main()
    except Exception:
        traceback.print_exc()


def main():
    target_url = "https://download.autodesk.com/us/samplefiles/acad/architectural_-_annotation_scaling_and_multileaders.dwg"
    data = requests.get(target_url)
    sideDb = Db.Database(False, True)
    with tempfile.NamedTemporaryFile("wb", delete_on_close=False) as f:
        f.write(data.content)
        f.close()
        sideDb.readDwgFile(f.name)
        sideDb.closeInput(True)
    filename = Path("test.dwg").absolute()
    print(filename)
    sideDb.saveAs(str(filename))

Wicked, cheers!

@CEXT-Dan , maybe it's worth adding a method to load dwg/dxf from a stream?

It’s not supported by AutoCAD. I tried to do this once while using SQL to store blocks. Temp file is the only way
