SolidWorks - Zebra Stripes


Zebra Stripes. Some of you might have come across to this function and was wondering what the purpose of this function is. For those who haven't seen it yet, you can access this function from Evaluate ribbon > Zebra Stripes.


The function of zebra stripes is to simulate the light inspection. This inspection is typically used to inspect the surface of a car. Light inspection is done by shining parallel lights unto the inspected surface. The reflection of the lights would form a contour on the surface, making any imperfections easily detected.

When the zebra stripes function is activated, a contour profile is shown on all surfaces of your model. Even this function might not be particularly useful for solid modelling, it is a very useful function to make good surface model.

Below is an example of using the zebra stripes function to identify your surface model.

Zebra stripes - bad model

Spiral or circular pattern indicate that the surface has dent/bulge
