Remove the empty layers

How can we remove the empty layers from drawing?

You have to do it manually one by one.


Edit: not quite true. In 2.2.0 you can select more than one layer in one go. See below.

You have to do it manually one by one.

yes its right way

Multiple layers can be removed using [Shift]-Select (left mouse button) or [Ctrl]-Select:

[Shift]-Select for a contiguous group of layer:                               Or [Ctrl]-Select to a non-contiguous group:
                         

A dialog will be shown to confirn the deletion of multiple layers:


You can also filter  to list a group of layers:
         

... and then select multiple layers as above.

There is one more quick way to remove empty/unused layers.
You just create new empty drawing. Then you select all objects in your original drawing and copy them to the new empty drawing. Only used layers are created in the list of layers of the new drawing.

Hey, that's a very good trick!
But keep in mind that in LibreCAD V2.1.3 you will lose the hatches (bug, solved in 2.2.0). Also you will have to take care that the new empty drawing has the same settings in Current Drawing Preferences.
So in further development of your trick, I had the thought, why not re-import to the same, but cleaned up drawing?
Instead of Copy, use Cut. Then, if you are lucky to have V 2.2.0 rc, you can delete all the layers, except 0, in one go. And then Paste back the contents including the used layers only.

Hi, that's really better way. I will use it. Thanks a lot for your post.

Hello Gary,
unfortunatelly the selection of more than one layers does not work for me.
I am using windows version of LibreCAD 2.0.11
I supose, based on the look of your dialog window, that you are using LibreCAD in Linux system.
Maybe the list of layers has more functions under Linux or there another glitch which I am not aware of.
If you know anything about it, please let me know.

Regards.

You have to use LibreCAD 2.2.0 (the latest is rc2) to select more than one layer.
Available here https://sourceforge.net/projects/librecad/files/Windows/NightlyBuilds/master/LibreCAD-Installer-2.2.0-rc2-1-g6dfb387c.exe/download
or if you are still on XP https://sourceforge.net/projects/librecad/files/Windows/NightlyBuilds/master.xp/LibreCAD-XP-Installer-2.2.0-rc2-1-g6dfb387c.exe/download
You may also try the portable version https://portableapps.com/node/63458
You can test and use this while keeping your current installation.
 

Hello Dellus,
thanks for links. I have tested the portable version and the selection of more than one layers works. Thanks
