I’m currently using a node from DataShapes to allow for manual selection through UI but the selected elements do not stay highlighted…
I’ve also tried the python-solution from @ c.poupin but this also doesn’t keep my selected elements highlighted. (This was a solution from 4 years ago, so maybe there was a change in the API?)
Okay, so this is weird. When trying it on a Revit sample file (within the same Revit session), the highlights do show up…
I’m baffled as to why it does not work on my own file…
