QCAD unable to open DXF files

Postby Webbo » Thu Jul 28, 2011 11:02 am

I have bought QCAD Version: 2.2.2.1 [Professional]
Date: Jun 11 2009
(c) 2001-2008 by RibbonSoft GmbH,
Andrew Mustun
http://www.ribbonsoft.com
Modules: None
Qt Version: 4.5.1

running on Windows 7 Professional, Service Pack 1

I have DXF files created from DWG files using the Teigha File Converter. version 3.05.0.0 using Qt version 4.7.1
I open the file with QCAD, there is no error message, but there is nothing on the graphic screen, there are no layers in the layer list and no objects in the object list. Indeed there is no indication that any data at all was read in. I have tried converting the DWG file to various DXF formats but the result is always the same.

Any help would be greatly appreciated

It could be that the file only contains entities that are not supported by QCAD (that's mainly the case for 3D entities and some rarely used other entities).

Please send us the file for verification to info [at] ribbonsoft [dot] com

Reluctantly abandoning XP, my Drafix CAD will not satisfactorily run under 7, Linux or (memory hungry) emulators. I have used its native .cad file format since 1988 for all my domestic projects (I am not a professional) knowing that it exports format include .DWG and .DFX viz.
“ AutoCAD Conversions
Design CAD 2D Conversions
Drafix CAD Ultra, Drafix 1 Plus, and Drafix Port File Conversions
HPGL and PLT Conversions
IGES Conversions
Planix Conversions
Windows Metafile Conversions”

QCAD writes under ‘QCAD Features’
"Features in italic are available in QCAD Professional only.
Supported file formats:
DWG
read support for format version R2.5 through R27 (2013)
write support for format version R12 through R27 (2013)
DXF
read support for format version R2.5 through R27 (2013)
write support for format version R12 through R27 (2013)[/i]
DXF version R15 (2000) [QCAD Community Edition]"
i.e R15 is not in italics.

Can you tell me whether the Drafix version of DFX can be imported by QCAD Community Edition. Thank you. SW

There are various different DXF versions and flavors. The best way to figure out if your previous CAD solution produces DXF files that are compatible with QCAD is to try and load such a DXF file with QCAD:
