Hi Franz
What warning message do you receive?
you can post a picture .....
in each case the nod file. It is connected with two objects
referenced, the seat's skin and the line it represents
its axis of rotation ...
so clearly first you have to open the 3dm file
make sure there is a connection in the Object by Name nodes
and then run ...
If, on the other hand, you look at the red-lit icons, then you say
that not updated the extension library ...
Strange, the 3dm file is very light, so is the file nod ..
I could not tell you anything else ...
