Wall Footprinter

Hi - I used the Wall Footprinter in my model for visual clarity based on this post: https://answers.flexsim.com/questions/110372/visualization-of-walls.html However, after running the model for about two weeks, I see it runs slowly. When I recorded the performance profiler, I see that the yellow area shows the Wall Footprinter, but the number of hits is low. What does this mean?

Also, to remove the Wall Footprinter, is it sufficient to delete the node from the model tree since I cannot locate it under the library/toolbox?

Yes you can delete it - it's just the OnDraw code that is being called. I've also noticed that you have dividers under all your walls - that seems like unnecessary duplication.

@Jason Lightfoot The barriers are needed. I've used them in situations where there's a rack next to the wall, and operators need to retrieve items from the rack as I saw they pass through the wall to grab items from the back of the rack instead of the front. The back of the rack is closer for them and on their way. As for how they actually get through the wall or divider, I'm not entirely sure, but that's why I've added barriers there.

@Maryam H2 Please see the attached model demonstrating you should not need them with this location overlap :

Despite this the operator still does not walk to the closest point shown or pick through the walls as you imply.

PickThroughWalls.fsm

If you have an example where you think they ignore the walls, we'd like to take a look at it.

@Jason Lightfoot In my model, there is a long one-way corridor that operators must travel to reach the designated racks, as shown below. If we modify the Slot Assignment Strategy to anything other than "First Slot with Space," operators may not necessarily do this behavior since items located at the front of the rack and they need to travel to front of the rack. But, they tend to retrieve items closer to the back of the rack and pass through walls if they items they find is closer to the back of the rack.

Also, in my model have dividers in addition to the walls and they still do the same.
