Hello everyone. I posted a couple of days ago with my problem, but didn't get any help. Hopefully you wont mind if I ask again. I have an Autolisp routine where I can insert simple 3D objects on request. I am promted to input the X, Y and Z dimensions and the object is generated into my drawing (attributes and all !). I recently re-installed R2002 onto my new computer and since then, whenever I bring these objects into my drawings, they are grouped together. When I try to select one of them (to move etc.), they are all selected. I have to explode the items to enable me to move them. The Lisp routine is encrypted, so I can't work out why this would happen since re-installing Autocad. Can anyone suggest what may be happening here?? If I can get some help as to what may be happening, I might be able to solve it. (I'm pulling my hair out here guys, not much left. Any help would be much appreciated). Thanks in advance.
