This issue has been raised by me in the past, as long ago as V4… Doesn’t look like there is an easy way to access AutoCAD (dxf,dwg) export settings/schemes in a script… I thought by now that the schemes might be stored in the general .xml settings file, but I don’t see anything there. Previously, they weren’t even exposed in a visible registry key, there was a hack to get at them via the registry that Dale posted once, but it’s not an easy one.
I didn’t see anything either in RhinoCommon that looked promising, maybe I missed something…
For me at least it would be useful to see what schemes the user has stored so as to be able to set one on export; far better would be to be able to create a scheme in the script or be able to set the export parameters without having to create a scheme first.
Has any progress been made on this or is it still in the V4 and earlier stage…?
