# Make dashed (or dotted) circle appear like powerpoint wheel animation

I am very new to blender, so I am still learning some features. I would like to make an animation like the one below.

My question is: how to make a dashed or dotted cirle appear like a powerpoint wheel animation?

Thank you!

• Please see array modifier which can duplicate a mesh from 1 to n times and have a rotation. So array modifier with a rotating empty is a typical way. – atomicbezierslinger Jan 19 at 15:39

The driver for the second input of the subtract node is #(frame - 1) / 120. The 120 is the number of frames for one rotation (at 60 fps this is two seconds).
