Dan Sawatzky’s Texture Magic:
What is it about dimension that makes us look twice or look a little longer? There’s some sort of magic in 3D graphics that draw the viewer and deliver those few extra seconds for the sign to get its message across.

CNC routing and cutting lets businesses take advantage of this phenomenon by making it practical to add dimension to signs. CNC routing opens a lot of possibilities for a creative sign designer. It can mean layers, which let you have an even more dramatic 3D effect. It can mean textures, which create more interest. It can mean convex and prismatic effects that give lettering more impact. All of this could be done on a sign before the dawn of CNC routing and cutting but it was much more time-consuming and therefore more costly.
