Parsing via Blocks instead of Layers

[jmlg10]

Hi,

when displaying the DXF, there is a list of layers used very useful for analysing the file, but sometimes it could also be useful to show/hide "Blocs" instead.
Could it be possible to give a choice to parse the file as Blocs instead of Layers?
It could also be useful to be able to analyse entities to define their type, polyline, arcs, curves...

Many Thanks
