Hello everyone,

I'm modeling a virtual factory based on an existing building for a future production line. My goal is to determine where each machine should go to optimize the flow. The main issue is that parts will go through doors several times and will cross paths, I would like to simulate that. 

I would like to simulate transportation either with humans or forklifts. How can I do that? (I've tried to create pathways and walk paths without success) 

Many thanks
