Remove similar layers side by side

[Anonymous]

Hi, all my layers in AutoCAD are in the form of an attached image. What should I do to be able to delete one of the layers? The number of layers is too large?

Set LAYLOCKFADECTL to 80 first.

Then isolate a layer to check what actually contains to not remove objects you don't want to. Then hit Ctrl+A and DEL. Unisolate and again, repeat the process with the next layer.

@Anonymous ,

A similar concept as @ВeekeeCZ.

1. Purge and -Purge All Items.
2. Unfreeze and Lock all layers, then unlock and erase your specific element.

Another option is using the QSelect Command and then erasing.

Hello, thank you for your solutions, friends, but my problem was not solved and I put the file for you. If you find a solution, please let me know.

@Anonymous ,

Unfortunately, these duplications are on the same layers and cannot be isolated.

You will have to manually select the ones you want to delete.

Another option is to restore the file before the file was saved with these duplication and make sure all other updates have been applied.  Right click the drawing file in Window Explorer and select "Restore previous versions" > select date (if available).

The problem is not Layers [as AutoCAD uses the word].  Those copies of the same thing close together are on the same Layer [here both Text objects and both Polylines are on the same Layer]:

so no Layer-based approach can fix the duplication.

But the duplicates are at different elevations.  Viewed from the "front" instead of from above, it looks like this:

Maybe that's what you meant by "layers."  One set of the duplicates in my first image is in that upper band, and the other in the lower band.  From this view, you can easily ERASE the upper band with a window selection, if you can determine that everything in it is an unwanted duplicate.  Isolating Layers could help with that determination.

Great catch @Kent1Cooper ! 

I did not even think about that option.

Objects at elevated level moved to the  *_elevated layers.

Hi,

I see differences not just in Z-value, sorry.

>> my problem was not solved and I put the file for you

I tried it, but the problem you have is that the geometry is not just duplicated by a copy command, the duplicated entities have different vectors, here you can see the distances measured between some of the dup's:

...which makes it now difficult to find these entities (the original and the duplicated one) together.

Do you know how they were created?
