Hello Everyone, I'm trying to figure out if there is an easy way (lisp maybe) to merge multiple layers into one layer, while retaining the linetype of the original layers, and maybe the colors too, but the retaining the colors is not as important as maintaining the linetype. Most of the entities drawn are bylayer, thus the problem with the linetypes. I know, I know... Why would we want to merge all our layers? It has to do with some legality stuff when we are working with certain contractors. If anyone know of any tips and trick on how to do this, that would be greatly appreciated. Thanks in advance for you help. Sam
