# Load DXF Documents from Reliable Sources
id:: 655fa1b8-2647-41bc-b7b1-9dbb29689907
- tags:: howto, readfile
- This works well with DXF files from trusted sources like [[AutoCAD]] or [[BricsCAD]], for loading [[DXF]] files with minor or major flaws look at the [[ezdxf.recover]] module.
- ```Python
import sys
import ezdxf
try:
doc = ezdxf.readfile("your.dxf")
except IOError:
print(f"Not a DXF file or a generic I/O error.")
sys.exit(1)
except ezdxf.DXFStructureError:
print(f"Invalid or corrupted DXF file.")
sys.exit(2)
msp = doc.modelspace()
```
- see also: applications that do fit my criteria of a [[Reliable CAD Application]]

- # Load DXF Documents from Unreliable Sources
id:: 655f9217-535e-4f2e-8502-387a23853929
- tags:: howto, readfile, ezdxf.recover
- If you know the files you will process have most likely minor or major flaws, use the [[ezdxf.recover]] module:
- ```Python
import sys
from ezdxf import recover
name = "your.dxf"
try: # low level structure repair:
doc, auditor = recover.readfile(name)
except IOError:
print(f"Not a DXF file or a generic I/O error.")
sys.exit(1)
except ezdxf.DXFStructureError:
print(f"Invalid or corrupted DXF file: {name}")
sys.exit(2)
# DXF file can still have unrecoverable errors, but this is maybe
# just a problem when saving the recovered DXF file.
if auditor.has_errors:
print(f"Found unrecoverable errors in DXF file: {name}.")
auditor.print_error_report()
```
- For more loading scenarios read the docs of the [[ezdxf.recover]] module.

- # Load DWG Documents
id:: 655f9dec-1dd2-4cd0-91b8-fba13b828a73
- tags:: howto, readfile, DWG, odafc-addon
- [[ezdxf]] does not support the [[DWG]] format, but you can use the [[odafc-addon]] to load [[DWG]] files via the [[ODA File Converter]]
- ```Python
import ezdxf
from ezdxf.addons import odafc
try:
doc = odafc.readfile("your.dwg")
except IOError:
print(f"Generic I/O error.")
sys.exit(1)
except odafc.ODAFCError as e:
print(f"Invalid or corrupted DWG file.")
sys.exit(2)
```
