Hi Cor,
have you experiences in it? I have no experiences with loading DXF :-(, but for my self I made in history some VBA routines to export major AutoCAD/Bricscad Elements(e.g. lines, polylines, circles, blocks, texts) to ACSII.
Also for export to MySQL spatial. So it's easy possible to use CAD graphics in GIS (MapGuide Open Source). I suppose it's intreting because MapGuide can render this graphics by http request. In this way CAD drawings are visible in an Android phone. That's my actually state.
And because all graphics are saved in a database, their properties should be processable by SQL. Okay, depending on scaling, complexity an some other conditions. Withs it I will play around in the near future.
However I'm allways intrested in working with AutoCAD/Bricscad/MapGuide related with Android.
