## Highlighting Surfaces and Curves with the Mouse

PC-DMIS gives you the ability to quickly and easily highlight CAD surfaces and wireframe elements by simply hovering over them with your mouse. This lets you get a quick overview of the available surfaces or curves on your part model. This is called Mouse Over Highlighting (MOHL).

Example of Mouse Over Highlighting

To use the MOHL functionality, hold down the SHIFT key and move the mouse over your part.

If you have selected Surface mode from the Graphics Modes toolbar, PC-DMIS highlights in the highlight color the current surface under the mouse.

If you have selected Curve mode from the Graphics Modes toolbar, PC-DMIS highlights the current curve or wireframe element under the mouse.

If using MOHL with a textured bitmap applied to surfaces of your part, you should set your Z-Buffer Depth to a value lower than 32 bits. A setting of 32 or higher may cause jagged highlight lines to remain on your image until your refresh the Graphics Display window. See "OpenGL Tab".
