Hi everybody,
 
	I'm a PhD student of Naples and I'm working in a complex project that involves Labview code (that I know very very basically..).
 
	I'll start to ask you help for a little problem  
	I had imported a STL file (3D file) in Labview (below there is a screen shot) and I manage to get the coordinates x,y,z of  the point of the STL file that  I select with the mouse click.
 
	Now I would need to create a marker ( or a little sphere or a red point ) on the STL file where I clicked and, if I click on an other point I would need that the marker created before was deleted and that a new marker be created on the new point I clicked, I mean that on the 3D object must be always only one marker. (I'm sorry for my English, please tell me if there is something not clear).
 
	I would specifie somethings:
 
		the Z coordinate is not important to create the marker/point/sphere because it gona be create on the surface of the 3D object I've imported at the start of the VI (STL file).
	
	
		I must be able to continue to move the 3D object in the scene and create the marker/sphere/point only when I click on the object surface
	
	
		I need to storage the X,Y marker coordinate
	
	
		on 3d onbject must be only one marker at the time
	
	 
 
	THANK YOU IN ADVANCE
