Hello all,

I made a script that places adaptive families at points.  
This all works great but i noticed that sometimes, families placced in a previous run randomly disappear after running it again (after closing the script and reopening).

i use no element.delete nodes and i simply only place familes at random points and set some instance parameters.

Can element binding persist after closing dynamo or is something else going on?  
This even happens while using Dynamo player

I have deleted all the elments and started it in Dynamo player, now it works without deleting elements 🤔

Yes, this is all how [Element Binding](https://forum.dynamobim.com/t/element-binding-in-revit/31612) in Revit works. Read the linked topic and things linked from there closely for more info.
