Had great fun assembling this model and getting all the moving parts to work correctly. Without the capabilities of PhysX, this would not have been so easy. See finished model here
My virtual Meccano Outfit is now complete (all 230 interactive parts).
I have put together a software demo which illustrates a layout of all the parts and the user interaction therewith.
Details, pics, UTube video link, and a free download is available here
