Good evening Dynamo Community!
I am placing wall opening families by ducts from a linked file.
They are placed in the right spot but they only show as rectangles in Revit.
If i make any manipulation in revit, for example changing size or level the hole instantly is there.
I´m pretty confused because it already worked a few times, some times by running the script again. I already tried new transactions…but i really can´t get this to work. Also changing parameters like size or level with dynamo doesn´t help 
Would be really happy about any advice! 
Hmm…
How about a hack? Does ‘End Transaction’ then SetParameter Offset +10 followed by SetParameter Offset -10 work?
Good luck,
Mark

Thanks for your reply Mark, i already tried that but it doesn´t work.
I thought the problem could be the host, but it finds the wall as host…
I added a bunch of transactions and found the “solution”, so you were right mark!
I have to set one parameter a second time to make it work. Until now i always tried to set the same value twice, but it only works if i set 2 different values.
Would be interesting why this happens…but i´m good if it works
