Using Revit 2021 Dynamo: [image] When I am opening a dyn file it is showing all of the nodes on top of each other. The file looked like this: [image] But when reopened it looked like this: [image] If I space them out I get this: [image] So all of the Code Blocks are toast… If I make another Code Block it looks like this: [image] Has anyone seen this before? i am going to reinstall.

To date, every time it has come up it has been due to a conflicting add-in or lack up update. Update Revit to the latest version that you are using. Launch Revit, open a model, launch Dynamo, open a graph, and see if the issue persists. If so, proceed to step 3. If not you’re good to go, but try to keep updates installed going forward. Close Revit, and then disable all Revit add-ins. Launch Revit, open or start a model, launch Dynamo, open a graph, see if the issue persists. If so close Revit, and provide your Revit Journal and Dynamo log in this thread. If not, proceed to step 5. Close Revit and re-initiate your Autodesk provided add-ins. Repeat step 4 and confirm the issue doesn’t persist. If the issue pops up, be sure to update the add-in. If the issue doesn’t pop up, proceed to step 6. Close Revit and re-initiate a few add-ins and re-test. Do maybe 3 or 4 at a time until the issue reproduces, keeping any offending add-in out until you have tested all passing add-ins. Update the offending add-in, or keep it off the system until a version is issued which resolved the problem.

Hello Gentlemen, Was there a solution found to this issue? I’m having the exact same problem with my nodes collapsing on top of each other and then running null even if I do un-jumble them. My coworker’s computer opened the same script I was using without issue (he does not have the same packages I have). I uninstalled all packages for Dynamo, and sure enough, Generative Design did not uninstall, no matter now many restarts I did. I uninstalled the package through the control panel, and now Dynamo works again. If there is a solution found to this, please let me know. For now I will use Dynamo without GD.

@ariderAEE99 Do you have any other Revit add-ins installed on the machine where you were seeing this issue?

@nate.peters The only add-in we use as a company is Bluebeam (and Lumion LiveSync; I’m not sure that counts). [Revit Add-ins AEE99] I suspect this is not the cause, as my coworker’s computer reads the script without issue, and he has the same add-ins as I do. Thank you, Amanda

Combination of add-ins and packages can do it. Also your Dynamo version might be different than your coworkers. Make sure everyone has all Revit/Dynamo updates installed, then check the items in your Dynamo’s notifications window (the green ! icon in your menu bar) and/or in your Dynamo log file.

Hi @ariderAEE99 - if you can reproduce this please send me (or post here) the output from this listDlls tool - it should be pointed to Revit.exe after the issue has occurred. [image] ListDLLs - Windows Sysinternals List all the DLLs that are currently loaded, including where they are loaded and their version numbers. it will generate a list of all binaries that are currently loaded into Revit - it may give some direction. something like listdlls -v Revit from the command line

It happened to me when I had 2 version of Dynamo installed one older 1x and 2x version but by default opens the older version of Dynamo and nodes are on top of each other

Thanks @Michael_Kirschner2, I’m trying to recreate the problem but having poor luck. I reinstalled GD and didn’t have any issues with it. If I run into the issue again I’ll post the listDLL. As @RubenVivancos pointed out, I noticed a version of Dynamo 0.9 was still installed on my computer, so I uninstalled that (however, this was still installed at the point of time I had resolved the node-stacking issue).

Edit: Same issue reoccurred. I’ve attached a screen capture this time. I haven’t touched Dynamo since the last time I posted, when it seemed to be working fine. [Dynamo Failure] @Michael_Kirschner2 I tried to figure out the DLL software, but I know little about computer programming and I’m not entirely sure how to use the ListDLLs utility. When I open the downloaded application, a window opens with a list of all DLLs and auto-scrolls to the bottom, and then exits out without prompt. I deleted Generative Design (once again) that I had previous reinstalled (which was working - please see my last post), and the nodes are now fixed in my Dynamo. Hope this update helps figure out the root of the issue.

Can you post your Dynamo log file from before uninstalling generative design, and the associated Revit journal?

@jacob.small Tried to attach the journals, but I’m getting a warning saying that new uses cannot attach files.

Wanted to share my solution in case it helps anyone else.
