Where does this
"skp23ds.dll" file come from ?
(I do not see it included in the SketchUp SDK.)
EDIT: Okay, I found it.
"Exporters/Skp23ds.dll" is one of SketchUp’s own native exporter libraries for use internally by SketchUp ONLY. It is not for use in 3rd party applications.
To cause SketchUp itself to export to a 3DS file we must use the Ruby API …
It can be invoked from a Ruby C extension that is running within SketchUp’s process.
Thank you very much!
I will try some other ways!
I would suggest that you need to use a C library for 3DS files along with the SketchUp file SDK.
Here is one I found just by doing a internet search … (but the last change was 4 years ago.)
