Dxf importer options hash tags

[reedwhti]

Hi
Im new to the forum. And have done a little ruby scripting related to automated exporting of dae models... So im a bit lost here with what seems like a simple thing.

With a dae export I found these options listed in a forum topic:
options_hash = {
:triangulated_faces => true,
:doublesided_faces => true,
:edges => false,
:materials_by_layer => false,
:author_attribution => false,
:texture_maps => true,
:selectionset_only => false,
:preserve_instancing => true }

status = model.export 'mycollada_model.dae', options_hash
That is great.
And now I want to import dxf files with a ruby script and control the import options like above.
I have search around for a list of option tags and came up empty.
My questions for the forum is:

1. How do we list the option tags from the App? In the Ruyby consol I would like to iterate through
   Sketchup.importers or something like that to get all the importers and call 'options' to get a list of options. It seems there is a disconnect on getting these from that App level.
2. My other question more specifically...what are the options for the dxf importer?

Thanks in advance.

Unfortunately only some exporters accept a hash as arguments.
To the best of my knowledge DXF is not one of them.
The last options set manually are always used irrespective of the passed arguments...
