Message
Port face selector root contour is not unique.
Severity
High.
Detailed Description
A port face selector is an internal intermediary object between a structural slab and one of its bounding structural members.
A root contour is an internal object and a parent of a port face selector but also a parent of a structural slab.
If a port face selector's root contour is not unique, this demonstrates a serious problem.
Possible Cause
A relationship between a port face selector and its root contour is instantiated more than one time, which can be the result of an automation problem or a copy and paste problem.
Possible Impacts
The slab limited by this member will not correctly evaluate boundary offsets.
What You Should Do
Because this object is internal, there is nothing that you can do directly.
