Hello All, I have an issue with a map that seems to be caught in a loop after a script that creates elevation views based on the location line of a storefront wall has been executed. I am new to the world of Dynamo and I found the [LearnDynamo](http://learndynamo.com/about/) website hosted by Jeremy. I was using the Mod 2 map as a training tool and added some flare here and there, but the majority of the map, including the script, was created by Jeremy…so full credit goes to him. There was one other node that I used from the Clockwork Package…Element.Location, full credit to the developer of that package. The Mod 2 map from the website above works well, but when I tried to expand on the idea trouble ensued. I am using the Element.Location node to generate line data to be used to create the crop region of the interior elevation view. At the front of the map I am using a filter to only select the storefronts that I have typed tagged beginning with “SF-”. It seems to me that all of the logic through the lists is correct and valid, but I have no idea when I go and run the script at the lower right hand corner of the map my session of Dynamo becomes unresponsive and I eventually have to “X” out killing Dynamo and Revit. I am currently using Revit 2016 with Dynamo Core/Dynamo Revit 1.2.0.2690. As a new user I am unable to attach any files…is there a way in which I can share the map with the forum? Any help and/or pointers in the right direction would be most helpful. Thanks. ---

@EENagel Looks good to me. Is it not the same with you? [![](https://dl.dropboxusercontent.com/s/3mgwtrolke0jj7v/Elev.gif?dl=0) ](https://dl.dropboxusercontent.com/s/3mgwtrolke0jj7v/Elev.gif?dl=0) ---

No…when I run the map it seems to get caught in a loop. Dynamo/Revit becomes unresponsive and I have to close out of everything. I am running revit/dynamo on a virtual machine…don’t know if that is causing the issue. I’m going to test it out off of the VM. Out of curiosity, what version of dynamo are you currently using? I’m trying to see if we are comparing apples to apples. ---

From your screen shot above…dynamo freezes when I toggle the boolean feeding into IN[0] to true. ---

OK…I think I finally figured out the problem. There was nothing “wrong” with the graph itself, but rather with how the graph is executed. I had the Automatic option selected and was using the Boolean to actually generate the elevations. When I changed all of that to manual, everything ran smoothly. So, Pros and Cons of using Automatic and when/when not to use Automatic?
