AecObeject layers will not purge -
for AutoCad 2013:
draw a line on each of the offending layers,
then make sure you have your current layer set to zero
type LAYDEL,
select all lines on the AecObject layers
(select yes to continue)
purge and
the AecObj... layers are gone
thanks for the info below!
I am just adding a little more to roney75 solution. This is if you end up with many layers.
1. Open the drawing, select model space.
2. Change current layer to one of the "AecObjExplode_etc,etc" layers
3. Draw a line any place in model space on that layer
4. Change current layer to "0"
5. Put in command "laydel" select the line you put on that "Aec" layer
6. On the command line you will see: "Select object on layer to delete or [Name/Undo]:" at this point put in "n" for Name
7. A dialog box will show up with all layers. Select the ones to be deleted and this should take care of the items the purge is missing.
8. Important: Purge drawing then save. Objects will not be gone unless final purge is complete.
