<p><font face="monospace">I am not 100% sure how AutoCAD plugins
work, but I seriously doubt they can be licenced as GPL.</font></p>
<p><font face="monospace"><br>
</font></p>
<p><font face="monospace">If you link ( or Python `import` ) modules
within your plugins, they have to be compatible with GPL.
Therefore any proprietary module / binary linked would not
correspond to that requirement. </font></p>
<p><font face="monospace"><br>
</font></p>
<p><font face="monospace">Said otherwise, you cannot have `from
pyautocad import Autocad` in a GPL-licenced plugin.</font></p>
<p><font face="monospace"><br>
</font></p>
<p><font face="monospace">You are free to reuse any functional
workflows from QGIS and other concepts, as this is not subject
to copyright. But any reuse of code from QGIS or QGIS plugins
would have to be licenced under the original licence ( GPLv2+
usually ), and any linked code should be GPL-compatible.</font></p>
<p><font face="monospace">Also a grey-dark area would be any code
taken from QGIS and translated to C# : that would most probably
have to be under the same GPLv2+ licence.</font></p>
<p><font face="monospace"><br>
</font></p>
<p><font face="monospace">There are ways to avoid "GPL
contamination" between software components, but this kind of
advice would not help the opensource community, so I will let
you figure that out yourself.</font></p>

I want to be transparent with the QGIS community. The project
is inspired by QGIS workflows and uses common open geospatial
service concepts also supported by QGIS. If I later reuse or
adapt any actual QGIS source code, I will preserve the
original copyright notices, clearly document the specific
source files/functions used, and keep the derived work under a
GPL-compatible license.</div>
