Help with pathfinding

Hello, I’m looking for somebody that is able to point me in the right direction with this. I have a part and would like to be able to click on the part (grey) and then click on the red part, in end making the grey part move to the position of the red part.


Eventually there will be lot’s of grey parts and red parts so I think this is where it gets complicated.

I imagine that pathfinding and tweening might be used but I just don’t have the scripting knowledge to make it happen so any help is appreciated.
