I do need to find a free or cheap easy editor can be used to import dxf r12/r13 files, add layer names to it and export again the file.
I need this tool to import layered files into biesseworks cam, so to bypass the long and complicated procedures of this software.
Does anyone know what I should use?
If yes how must be done this simple operation with the suggested program?
I need it to convert dxf simple files into dxf files with layer names, I do not want autocad as it is expensive and not my cup of tea in principle.
I do not need to modify anything, add anything or remove anything.
I only need to import the dxf, mantaining groups and geometry types (for example polylines must be kept as polylines, arches as arches and so on), it is important as becomes easy to assign layer's names and the work will not be ruined by geometry approssimations and type changes.
At least the kind of lines and geometries must be preserved, if groups are gone it is not really fine but will be ok anyway.
So then I need to create layers with specific names.
Once done that I only need to export it again to dxf format, possibly again in r12 format (but I will ask the technicians which version is able to import the biesseworks so to be more precise with my question).
Nothing else I guess.
I do use another cad to draw and edit the drawings in general, but it is not able to create layers that can be exported to dxf.
