Layer reconciliation was introduced on the Autocad 2008 products (AUTOCAD MEP 2008, AUTOCAD 2008). As I understand this is an Autocad 2008 notification to inform the user that there is a new layer being added – specially if you are xrefing a drawing. Very helpful for people who are strict in their layer setting and standard. But for those who will just use the external drawing as a reference, this layer reconciliation turns out to be annoying rather than helpful.

When you see the “Unreconciled New Layers” notification on the bottom right corner of your drawing screen it is always a good idea to view the unreconciled new layers in layer properties manager and fix the layer otherwise this will surely bug you when you plot your drawings. Believe me! because if you are going to plot the drawing without reconciling the layers, the plot notification dialog box about the unreconciled object will pop up many times. If you have 50 unreconciled layers you have to act on 50 popup box before you complete your plot command. The friendly Ctrl+alt+del will come to the rescue, should you find yourself in a hard situation like this (boss is standing behind you, waiting for the print out of drawing )

So you know what to do the next time you see the layer notification as illustrated above. But what if upon clickng the wonderful “View unreconciled new layers in Layer Properties Manager” link you were welcome by the famous “MEP 2008 Fatal Error Notification box” what will you do then?

My advise, AUDIT & PURGE your drawing. This will remove the unused Autocad Blocks and layers in your drawing. Reconcile the drawing – if the error still persist then most probably the affected acad drawing may have exceeded the number of layer filters that could have been causing the fatal error. We have to delete these layer filters inorder to save drawing. I once encountered this error and when I look at the layer management I observed that layer names with different symbols and characters are present in my drawing. To workaround layer reconciliation without the encouter of autocad mep fatal error , reconcile the affected drawing by accessing layer manager (default shortcut command = LA). Delete the excess & erroneous layer filter by clicking the “yes” in the dialog box that will appear. Reconcile all the layers and you are done!

Should you have a nicer way to fix this problem please share by commenting on this post.

That’s all for today, I hope this help you in anyway.
