So I finally get to officially request a feature as a user!!!
Anyways, there already exists a skp action to launchEW (i.e. skp:launchEW@advanced-camera-tools). We would like to see if you can add a SKP action to launch 3dw. Either directly to a model, or (especially of interest) to open the “Share Model” page that the File -> 3DWarehouse -> Share Model gives.
Of course, this feature could be passed onto the Extensibility Team to implement through Ruby, but I think the precedence is set to do this through SKP.
