Hello,

I read this lecture online from a student in UC Davis about Mechanical Drawing (PDF format) on one of his pages there was this drawing with 6 layers  that I could control the layers by turning them off and on ( there was this bar on the left side opened that had these eyes next to each layer)

unfortunately the lecture has been removed from the site so i cant attach an image.

How can I create something like this for presentation?

Thanks

Alex
