Preventing Layers from Being Purged?

[Dana W]

None of these methods of creating graphical entities on layers will prevent those layers from being purged, because the entities can be removed.

Try and purge the 3 layers in the attached drawing. And note that DBLIST confirms there are no graphical objects in the drawing.

But they insert the blocks and then purge, by my understanding.

I moved your thread to the AutoCAD LT Forum.

Seems like a lot of trouble to go through just to keep a few layers from not being purged early on in the life of the drawing.

Put every conceivable layer in the drawing template file that everyone thinks they will need. The last person to work on the drawing is responsible for purging the layers, etc. that were not used. Done. If that person can't handle the responsibility then he/she should find a more suitable career.

I somehow didn't see all these other replies. So, months later - thanks all! Some good considerations.

ReMark, your comment made me laugh a little. I do wish it was that simple, but drawings are not necessarily ever "fully" completed. I had one recently that was dredged up from 2007 or so to add more equipment! I guess it's a good problem to have, as I work for the company that sells the equipment...

Dont forget you can add as many layers as you want at any time, a very simple copy and paste from a text file or scripts in LT ?

If you have acess to a full Autocad or post here you can export out all the layer details to a text file some one will do for you.

[ReMark]

New layers can also be added by way of a script file.

Personally i gave up on this block purge trick years ago as i would rather my users purged & audited there drawings, just educate your users to use the design centre save your template .dwt as a favourite location in design centre problem solved (so they don't even need to look for it).
