Wireframe with hidden lines

Here is something that has been with NX and Unigraphics for a long time but has been buried. Display your model in wireframe mode with hidden line removal, and have the hidden lines update dynamically.

NX3, Set this option when your in wireframe mode, Preferences -> Visualization -> Visual (tab) -> Hidden Edges (section) -> Hidden Surface (pull down)

NX4, Right click (3rd mouse button, in the graphics area) -> Rendering Style -> Wireframe with hidden edges

Now when you rotate the part you’ll see it in wireframe mode but rendered without the hidden lines, Similiar to shaded but without it being shaded. So performance will similiar to shaded.
