Hidden lines are shown as light grey lines in Wireframe display. To set model display style, you can use the following buttons on the Graphics toolbar.

Shading—Default setting. Shades the model. Hidden lines are not visible. The shading adapts to changes in model orientation. You can use this display method to view the contours of a surface or to print a copy of the model.
