(Apologies for the lack of graphics with this post. I was getting too many errors when trying to upload the workspace png to the forums… in any case…) The attached file shows the early development of a room data sheet script. After much searching I finally got the script to place the generated 3D v…

Try running the attached graph in Dynamo player and see if that clears things up for you. Create One RDS Problem Edit.dyn (122.7 KB)

Did not even touch dynamo yesterday but finally had time to try the code this morning. I’m still learning about the wait/pass node as my dynamo projects slowly increase in size and complexity. Also noticed you changed how the initial Room id string was passed. I’m sure that will be helpful when I e…

Update 18-10-17: Ok. Worked on this a bit more and new 3D views (in pairs) continue to overwrite previous ones. I’ve stripped out even more code to try to narrow down the problem area: Removed some of the 3D view processing go/nogo logic that checks previous views in case views were getting stuck…

It’s element binding (which is the other thing I did). It’s presence in the graph’s file indicates that you aren’t running this via Dynamo player, but via dynamo, and that you are not closing (without saving) the graph between runs.

An element binding issue? Interesting… Do you have any more information you can share about the mechanics of this issue? (Because, hehe, I’m suppose to be the Dynamo expert in the office. :thinking::fearful::cry:)

You are. I’m writing g up something more formal, but here are the basics: You don’t want Revit to place a new smoke detector in the active room every time you hit run, resulting in 10,000 duplicate instances when you finally see the category is turned off in the active view… nor do you want to have…

Thanks for the helpful explanation. I was really confused by the behavior of the 3D views overwriting because I just couldn’t see any possible root cause in the script. After thinking about it I do recognize the behavior you’re describing. The not saving workaround will have to do for awhile until …

There are solution alternatives built around python which avoid this issue, however you’re running the risk of making 30,000 duplicate elements that way. If this is a graph that people will use often you may want to consider utilizing the Datashapes MultipleInput++ node to generate a better UI for …

Good tip. I’ve download the package.

Halla @jacob.small , I’ve been using Dynamo for quite a while but for the first time I’m facing issue of overwriting, whereas i’m using Dynamo Player only. Revit 2021. Please let me know. Regards, Atharva
