Hello! Sometime in windchill i see that strange parts in part structure window
What is type of this parts? They are not display in visualisation window. But if i search that part by number - it opens correct with no problem.

What you are seeing is the Part Master. It means that the Configuration Specification that you are using is not returning a version for the child parts in this structure.
