[Qgis-user] Opening dxf files for 3D

[Nicolas Cadieux]

Hi,

I have not worked with the 3D in QGIS 3 but I did do some work with Qgis2treejs a few years ago.  As far as I know, you will not be able for visualise a dxf like you would in a CAD.  Qgis was, with that plugin more like a 2.5D where the ground surface can be modelled with a raster surface and flat polygons could be extended to make buildings with a z value.   Maybe I did not get to play enough with the plugin to find the proper functions...  maybe QGIS 3 has more built in function?  Not sure but I think you will need a real cad software in order to see a real 3D structure.  There are a few OpenSource  CADs, none of which I would work with professionally :( but they may be good enough for visualization.   FreeCad was one.  MeshLab or Cloud Compare may work with DXF.  Not sure. 

Please correct me if I am wrong anybody.  I would like to be informed if things have changed.

Nicolas
