   Hi,

I've a little problem reading DXF file with my own application.
In my program I see entities that in Autocad there is'nt, can be PURGED.

Reading che DXF file, how I can understand when a block (or entity) is not used (can be purged) and the i can leave invisible?
What is the attribute of an entity that can be purged, hw I can see in the DXF code?

Thanks,
Best Regards, Massimo.

	I suppose if a Block can be purged, it can be found in the TABLES section, but not in the ENTITIES section if it has not been inserted. Or...before making a dxf from AutoCAD, purge it first :)
