When I create a pipe network in one drawing and then import it into another drawing with LandXML I get the following message: "Multiple Part Families with the correct geometry for Pipe [Pipe - (xx)] were found." for each pipe in each network. In the new drawing each pipe is set to the first pipe type in the part list which is different than the one in the pipe network in the original drawing. Both drawings were created with the same drawing template and parts list.
What is causing this and how can I fix it?
