Answer 1

AFAIK there is no command line tool to do it. Much less a Javascript tool.

SketchUp itself does have the capability, so you can create a Ruby plugin to do the export when SketchUp is opened. So you can have a .bat file or whatever the Mac equivalent is, and let it run SketchUp with your plugin.

Or you can roll your own conversion tool using the SketchUp SDK. http://www.sketchup.com/intl/en/developer/su-api/ The SDK does not need the SketchUp installed, but on the other hand it does not have any built-in .OBJ export support, so you would need to implement the exporter yourself, only using the SDK for reading the SKP file. This might be quite involved.

Or use this ruby plugin for Sketchup sourceforge.net/projects/stl4su/files – Whitsun

SketchUp has an open source STL plugin which is accessible from the Extension Warehouse:

http://extensions.sketchup.com/en/content/sketchup-stl

The STL works for SketchUp Make (which is Free) and SketchUp Pro ($590). SketchUp Pro also includes a number of other export file formats, such as OBJ, 3DS, DAE, FBX, etc....

Can the exporter work in the command line (I don't want the GUI)? – Oliviero

Afraid not. That plugin runs only within SketchUp. – Koonce

Answer 3

I know its not programatically, but last version of Sketchup has the option directly to export to OBJ file.

File Menu -> export -> 3D Model -> Then select from the dropdown of extensions the OBJ.
