Hi whats the best way to line a set of objects. I know seems a simple question but not working for me. 
Using Populations added shader array, shows the orange squares but no object comes up.  Tried a simple shape but then they are still random along the shape. Is there a path tool or is that just the Paintshader. or something to keep orientated to the simple shape  
Trying to do a long wall with an wall object. 
Suggestions. Many thanks
