I have a drawing that has several layers that I cannot remove when
purging. I turn off all the layers except the ones I one to purge and
there are no lines there! When I try to delete the layer I get a error
message saying i cannot delete the layer. Has anyone got any
suggestions of how I can purge these layers?
That's a bit drastic. He will lose all views, viewport setups, UCSs, unused
styles and blocks.
The problem is more likely much simpler to solve. Check that floating
viewports do not have the offending layers frozen in them before you purge.
If that doesn't work, look into your block definitions. Some may have had
these layers "current" when they were made, so that even if there were no
entities on these layers, they are defined in these blocks. For that matter
see if there are blocks you can purge, they may contain the block
One more thing, if the layers came in with an XREF they cannot be purged in
the host drawing.
You can install Express tools if you did not yet, and there you have Layer
delete. That will work 100 %. You just have to draw one line with this layer
you want delete, and than choose Layer delete and select this line. Anything
in this layer will vanish.
