I open a Revit level in a project to select all elements of a category. I have a Dynamo script that selects all elements of a category via the Data-Shapes pakete ListView. I now want to switch levels without closing the Dynamo script, so that I can select the desired elements here as well, which wi…

Why not make your script in such a way so you can pick the Levels too with like a tick box?

That’s exactly what I want to do, but I can’t figure out which node to use for it. Would the ListView node be sufficient?

Yes. ListView from Data-Shapes gives you a selection box for each item in your ListView. You just feed in the level name as the keys and the level objects themselves as the values. That should return the list of level elements you select in the UI. A screenshot of your graph in action might be help…

Here a pic to selecte the level an selecte the windows, after this we want to change to the next level and selecte the windos again on this level and work with them. [image]

So you want to run the graph a second time? Why not just use player and do that if so?

Gotcha. So you’re not automatically selecting all windows from the selected levels. You want to select a Level from the UI, list out the available Windows from that Level in another UI selection, select the Windows you want to include, and then repeat the process for another Level. Is this because y…

[image] Nick_Boyts: So you’re not automatically selecting all windows from the selected levels. I would do it like this tbh (select the windows on selected Levels), but maybe your worklow doesn’t allow for that(?).

Sounds like the workflow becomes “all elements of category” windows. Then “select levels” with the Datashapes UI nodes. Then filter by bool mask to remove windows which are not on the selected level.

Hi, Thank you for your suggestion; it sounds very good. I’ll give it a go. I’ll work through it step by step in the Player. I’ll start with one level at a time, select only specific windows, and add the parameters with their values until I’ve applied the parameters to all the windows in that leve…

You still could select Windows on selected Levels only using Data-Shapes though (if you want to). So you can do it all in one go. Not sure were you are stuck using this approach.
