DXF layer names

saunajumal

I'm trying to use -Sketchup to DXF and STL convertor plugin- but it takes layer names from -Entity name-. What I need is it to create layer names from definition name (the same name you give to component at first).

I found that this part of code is related but dont know how to change it:
#Componentinstance entity
elsif( entity.typename == "ComponentInstance")
if entity.name==""
entity.name="COMPONENT"+$component_count.to_s
$component_count+=1
end

After some change I now have the code like that:
#Componentinstance entity
elsif( entity.typename == "ComponentInstance")
if entity.name==""
entity.name="LAYER NAME"
end

Can anybody tell how to change it and use definition name? Plugin can be found http://www.guitar-list.com/download-software/stl-dxf-converter

Unfortunately it's perhaps much more complex than that.
There are several methods def dxf_.... which are expecting an argument ' layername'
In other methods the arguments passed place say entity.name for the 'layername'
This is then used inside the method when calling other methods thus
dxf_write_face(entity,tform,layername)
Since at this point we are iterating an array named ' entities' we know ' entity', so you can substitute entity**.definition**.name instead ?
Therefore

elsif( entity.typename == "ComponentInstance")
         if entity.name==""
           entity.name="COMPONENT"+$component_count.to_s
           $component_count+=1
         end
         others = dxf_find_faces(others, entity.definition.entities, tform * entity.transformation, entity.name,dxf_option)
      else

becomes

elsif( entity.typename == "ComponentInstance")
         if entity.name==""
           entity.name="COMPONENT"+$component_count.to_s
           $component_count+=1
         end
         others = dxf_find_faces(others, entity.definition.entities, tform * entity.transformation, entity.definition.name,dxf_option)
      else

The code also renames any unnamed instances - to stop that add ### in front of the entity.name= code etc...
This might occur more than once you need to check through >90000 lines of code...

Thanks, works perfectly for me - every component is on its own layer and CNC machine can read layers automatically for toolpaths.
