Hi all.... I need a command to change layers. This is how it would work Select Command: Change to Std layers user input: cross a section of the drawing that will be changed prompt: which option? user input: A when user crossed a section of the drawing, 4 layers were selected 1-wall 1-text 1-dim 1-footing (or 2-footing, depending which layers were current) the "Change to Std layers" command changes the selected layers to: 1-std-A-wall 1-std-A-text 1-std-A-dim 1-std-A-footing It would never change 1-wall to 2-std-A-wall. see what I mean? sorry if I'm not explaining this well. I am using AutoCAD 2006 Does this already exist? Can someone help me with a routine? Thanks, jojo
