Thanks but by using this node, you lose the “host” element, see in the picture this is written “Non référencée” but the main subject is to copy the element and place them at the same place in the same host…
Hosted family instances require a hosted means of placement. This would require a great deal more than ‘copy to document’ as the reference to the geometry in the link may not be included there, and if it was the host may not be kept consistent (due to the nature of link instances).
Thanks @jacob.small and @_Vijay .
Jacob : Yeah sure, but my C#, VB, C++ skills are inexistant
Vijay : Yes but there will be several times the same object.
Nevertheless i think, once copied in the structural model, i will manually do a rehost by reference plane, it does work well
