Part file appears to contains lines that extend to infinity and cannot be selected.
Solution
NX selection sometimes will not allow users to pick objects whose endpoints lie outside of the bounding box which defines the working envelope for a file.
To maximize the working envelope for the NX session, adjust the following customer default:
Gateway-> Visualization-> View-> Fitting->
Object Bounding Box Maximum Size set as follows:
39,370 in English
1,000,000 in Metric
Save the changes and restart NX. The lines are now selectable.
