<p><strong>@ Giovanni</strong></p>
<p>Fortunatamente lo conserva: <br /><a class="external" href="http://novarese.t15.org/gfoss/elba_32632.zip">http://novarese.t15.org/gfoss/elba_32632.zip</a></p>
<p>Se apri questo DXF nel Blocco Note e cerchi la stringa "UTM", esso è pienamente georiferito: come controprova, caricalo nella trial di Autocad Map, poi dai il comando _ADESETCRDSYS...</p>
<p>Il problema è che Qgis non ingloba alcun SR nei DXF, nonostante richieda di specificarlo durante il salvataggio...</p>
<p><strong>@ rest of the world</strong></p>
<p>Luckily it stores it:<br /><a class="external" href="http://novarese.t15.org/gfoss/elba_32632.zip">http://novarese.t15.org/gfoss/elba_32632.zip</a></p>
<p>If you open up this DXF in Notepad and look for "UTM" string, it's fully georeferenced: as countercheck, load it in the Acadmap trial, then type the _ADESETCRDSYS command...</p>
<p>The issue is that Qgis does NOT embed any CRS within DXFs, even if it needs to specify it upon "saving as"...</p> QGIS Application - Feature request #9639: Keep CRS when saving DXF fileshttps://issues.qgis.org/issues/9639?journal_id=494702014-03-06T04:47:39ZJürgen Fischerjef@norbit.de

<p>Well, applications (like Map) may save all kinds of data in custom dictionaries. The <a href="http://images.autodesk.com/adsk/files/acad_dxf2.pdf" class="external">DXF spec</a> doesn't mention ADE_PROJECTION. Do you know any spec that could help with mapping ADE_PROJECTION codes to EPSG codes and vice versa?</p> QGIS Application - Feature request #9639: Keep CRS when saving DXF fileshttps://issues.qgis.org/issues/9639?journal_id=561902014-10-11T05:12:13ZGiovanni Manghigiovanni.manghi@gmail.com
