I've seen some people use a functionality that goes something like this. In drafting, set view A as your active sketch view. Start the line command and pick geometry from view B. This starts the line in the active sketch view, view A, where the picked geometry would theoretically be. I can't figure out why this works on some PCs but not others. I can't find a setting that I think would control this. Any ideas?
First, the second view (that is not the active sketch view) is a Pre-NX 8.5 exact view. Then, you can hover over the objects and they are highlighted. But no point selection is possible, so there is no "real" selection.
The more probable cause is that the user does have an active sketch, but the line (or curve) command he uses is the non-sketch line. In this case, the created curve is not a member of the sketch, but it can be associative to the geometry - depending on the associativity setting in the dialog.
