Davo, like Alex suggests, there's lots of miss understanding between 2.5D and 3D. Most of my signs are not 3D. Often I don't even go to the extra effort of pocketing. Although pocketing allows for easy background painting while the letters are drying at another station. I'm not fond of gilding 3d signs. The one below is an example of pocketing & gilding. None of this is 3d router work. So while the background is drying, I'm putting on the gold size for the next mornings laying of gold.
