2. Ensure that the Graphics Display window shows your part model in Surface mode. It will not work in Wireframe mode. See "To Configure a View to be in Opengl Mode:".

3. Select the View | Path Lines menu option. PC-DMIS will perform this operation and display the probe's path lines inside the Graphics Display window. See "Showing, Animating, and Moving Path Lines".
