If I could chip in - one of my clients is a large industrial client.
They have two sides of their "mapping" group - Autocad and ESRI.
Then I show up : ). <br>
<br>
They use the DWG format - in fact most of my clients that have
autocad capability will send me DWG and when I go "hey could you
convert that to dxf" there is a general groan. So - I pop open
arcgis and convert. Now that I think about it I've never tried
converting data from dwg to shape or back to dwg with gdal. I don't
know if that is even possible (I need to look). TN's department of
Transportation runs a healthy mix of ESRI/AutoCAD/Microstation (I
think) but as far as a know no open source anything. I get the
question of "What about DWG?" more than I care to mention. <br>
<br>
Having DWG capabilites would be a huge gain for QGIS (I think). <br>
<br>
Anyway - my unsolicited .02 cents worth. <br>

Hi Micha,<br>
<br>
That is interesting - we invested a lot in the DXF export
capabilities of QGIS. Once this is finished I am pretty sure we
will also look to improve the situation regarding the import.<br>
<br>
Do you think import of DXF is enough or do we also need DWG
support? If so, the best bet would probably be the Teigha library
from the Open Design Alliance (<a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="https://www.opendesign.com/the_oda_platform/Teigha">https://www.opendesign.com/the_oda_platform/Teigha</a>),
which isn't available for free - but it is the library most other
GIS (eg. ESRI, Intergraph) and CAD (eg. Bentley, Bricscad, etc.)
are using. We would have to pay a membership fee, but it allows us
to redistribute the library with the software. Membership in the
consortium is affordable in my opinion.<br>
<br>
What are your thoughts on this? Would you also be available to
help with a crowd-funding effort? Do you see options besides
Teigha?<br>

could you elaborate why "it would be unrealistic to say we <br>

From our point of view, we need support for dwg. That side of
vendor lock-in is, unfortunately, even stronger that the ties to
ESRI. So we stay with Arc* not because of the GIS capabilites,
but more or less only because of the ability to read Autocad
plans and surveys.<br>
