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

How do you make a dashed or dotted circle appear like a powerpoint wheel animation? I would like to make an animation like the one below.

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. 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).
