Delete all objects on a frozen layer

[angiegauthier]

Hi Everyone!

Can someone tell me how (or if it's possible) with Lisp to delete anything that is on a frozen layer?

Thanks 

Angie

Thank you again, but it doesn’t delete any frozen layer. I would like something similar like LAYDEL, but that allows select many frozen-off layers at once (selecting the frozen-off layers from the layer properties manager will be better). To use LAYDEL the layer has to be active on, but in my case I want to eliminate the ones that are not active/off. ( I have a lot of layers in a drawing, so, if I turn on all the layers, it is going to be hard to find the ones that I want to eliminate.)

You don't need a special routine for that. Use MERGE command from LAYER PROPERTIES DIALOG and merge all the layers but e.g. the first one into that one layer. Then use LAYDEL for it. Even if you'll do that 30 times a day, it's still real quick.

And tomorrow ask the ADSK staff why this is not build in Layer Properties Dialog. I'll must get your answer... since is The Answer Day!

I purged before, the frozen layers and objects still exist. 

Nothing was erased.

The version is AutoCAD 2015

Thank you BeeKeeCZ !

Your suggestion is a good workaround; unfortunately my file has a lot of layers, and AutoCAD almost froze when using the merge tool in the layer properties manager (it took 25 min. to merge).

It will be useful to have LAYDEL in the layers properties manager window, so we can sort the layers and select many at once.

I don't know what to suggest.  The code in Post 15 works for me [again, removing all objects on those Layers, but not yet Purging the Layers] in both AutoCAD 2004 and 2016.

Are you sure the Layers in question are not locked?  Did you notice the change in the command name from the earlier DFL?

[FCort]

All the layers were no locked.

None of the layers and objects were deleted.

Thank you for the effort.

The 'nil' there doesn't mean it didn't do anything.  If you want it to not show that, you can add a line to the code:
....

  ); if
  (princ); "exit quietly" [read about it in Help]
); defun

....

Again, for me, even without suppressing that 'nil' return, it does remove all objects from such Layers.  I thaw the Layers and/or turn them back on and Regenerate, and none of the things I had drawn on them are still there.  We could work on getting it to Purge the Layers, too, but first I'd like to solve the problem that it doesn't remove the objects for you, if it really doesn't.  But I admit, I don't have any idea where to look for a solution, since I can't duplicate that problem....

Hi FCort,

could you please, share with us a sample dwg with with a few objects and layers?

Hi friends

I don't understand why isn't working for my file.

I'd like to deleting all frozen layers in my drawing.

Could you help me, please?

File attached

Thanks

It doesn't remove the Layers, just the things drawn on them -- use PURGE or LAYDEL instead.  It looks like there's nothing on any of them, anyway -- that is, I thawed and unlocked and turned on all Layers, and REGENerated the drawing, and it didn't look any different -- so you should be able to Purge them.

Thanks for replay,

Can't I use any code to delete all frozen layer in my drawing?

I've tried purge command, but ins't deleting the layers.

Laydel command, worked fine. But I have to delete one by one objects.

Thanks

I couldn't Purge them, either, after running my routine for removing everything on them [I didn't try the others].  I suspect that means you have something like elements on those Layers that are included in Block definitions.  Laydel will remove even those, but merely removing everything drawn on those Layers will not free such Layers up to be Purged.  I'll leave exploration of that possibility to you.

There are some layers from autocad civil 3D.

I was using a template from C3D.

maybe could be this causing the problem.
