The following describes how you can check the port attributes of a part exported from 3Dfindit to NX.
In an opened assembly, perform a double-click on the desired part. (There is only access to attributes for single parts.)
Under More, click on Qualify Part.
Click on Object Characteristics in the context menu of PIPE1.
-> Respective dialog is opened.
Here you can see, among other things, the attributes transferred by 3Dfindit.
