http://www.zwsoft.com/forum/viewthread.php?tid=1634 What am I missing here. ?!?! Yesterday while I was working I needed to quickly open a seperate dwg file. So, I dragged it from the folder it's in to the open zwcad window to drop it in and open another window in the process. But, I noticed that it was trying to insert itself into the current drawing. I did not want this so I canceled and opened the second file with the Open dialog in the file menu. That was fine until this morning when I realized that ALL THE LAYERS AND BLOCKS from the second drawing are now copied/inserted into the my first drawing. Worse is I cannot seem to delete them. I could not delete the layers from the "Layers Properties Manager" It just tells me "35 layers of 35 could not be deleted". It made mention of layer 0 and Defpoints that couldn't be deleted. But, I wasn't trying to delete those layers. (The initial drawing was big enough already, now there are well over 200 layers!!) Is this a bug or omitted feature, Is there a workaround? If not, please set me straight on what I misunderstand or am doing wrong. Please Advise .. TIA. zw_admin 2010-08-24 10:15:21 http://www.zwsoft.com/forum/viewthread.php?tid=1634&pid=13200 Have you tried the command [laydel] It deletes a layer whether there's something on it or not. Works for me. Robert bertdorf3 2011-01-05 14:39:29
