Does anyone know of an easy way to write CNC code for bulged objects to be carved from wood? In other words, if you were to want 3 dimensional carved grapes for example, is there a simple command that can take a 2D drawn circle and automatically bulge a surface a given amount? It would be similar to dipping a framework of 2D artwork into a bubble solution and automatically inflating all the areas into a set height bulge. It looks like the new Sears routing machine may do that. I would assume that some CAD softwares can do easily that, but I haven't seen that specifically. I can do it by building each surface with the proper gridwork of U and V splines and patching surfaces together, but it seems there must be an easier way. I can get from a surface to CNC code, so that part isn't as much of an issue as easily developing the 3D bulged surfaces.
