Convert All Objects and Nested Blocks to 1 Layer

[Anonymous]

I need to select an entire drawing and convert all objects including nested blocks to one and the same layer. Can anybody possibly help with a script?

Hi,

First use the command SETBYLAYER > All (for all objects) > enter>yes (to include all blocks) > enter

Enter to change all the layers including nested blocks to assign the color of layer.

Second use the LAYMCH > All > Enter, then choose an object with the layer which you have to set for all layers or type the name of the layer you want to set as final.

Here is a screen cast showing how to use the LAYMCH.

Thanks for your help. I've been playing with theses commands. The problem I'm having is that there are still nested blocks that remain on other layers.

When I select one and use "Block Edit" command you can see that they remain on their original layer. We export points to a total station and the handheld device works best if I can purge all but 1 layer. I can't do that with nested blocks unless I do multiple explode commands, then the file size increases quite a bit.

Hi,

Is it possible for you to upload the file so that I may give it a try ?

Here is a sample background we get from the arch/revit file.

It has nested blocks that remain on original layers. I would like to combine then purge all unused layers, basically get it down to 1 layer.

Thanks for trying.

Hi @Anonymous,

Thank you for posting your sample file here for testing. It looks like a lot of the blocks you're trying to change contain geometry that is placed on the individual layers you're trying to purge.

I believe you need to modify each of the blocks, changing all the geometry within them from specific layers to Layer=0, in order to achieve what you asking for here. I don't think there's an easy way to do this, aside from modifying each block via the Block Editor.

If you're open to using some customization, maybe the recommendation in this AUGI thread might help.

Perhaps some other users can recommend a different method?

Thank you, I will look into this.

Hi,

Sorry for the late reply.

You can try some lisps to do the work.

Here are some attached Lisps

1. Layerfix

    Description: Changes the block definitions to Layer 0, Other properties will remain . Will skip all

    Command : BL03

2. Fixblock

    Description: Puts all of a blocks sub-entities on layer

    Command : Blast

3. Beltb

    Description : change all Block Entities of definitions of a selected block and all

     nested block definitions within it to the Layer of the Top-level Block.

     Command : Beltb

Thank you. I will play with these and let you know how they worked.

Layerfix did the trick, thanks for all of your help.

Do you have an idea how can I do the same but in a mac autocad 2017. I tried everything that I see on the internet but those commands doesn't exist in the mac. And I've seeing some people posting some kind of code but i dont know how to ran it on a mac as well.

Hi Vinayv4v, thanks for posting your solutions.

Is it possible to modify the FixBlock LISP to select multiple blocks? 

[Vinayv4v]

Sorry.

I am not that good at programming.

[arkelec]

No worries, thanks for the quick response.

[Baltona]

thanks for the tip.  let me try out 

[Vinayv4v]

Also try the first suggestion. 

SETBYLAYER & LAYMCH as shown in the screencast.

[Baltona]

color didn't change at all , any advise please remember multiple blocks are inside single block 

[Vinayv4v]

Hi,

Use SETBYLAYER > Select objects > change by blocks to by layer > yes.

Then try the Lisp. 

[Baltona]

I had  tried several times upload lips but it did not loud up into system acad2017  two of those im having truble fixblock & layerfix

Hi,

Are you using the command APPLOAD to load the Lisp ?

You are not using Autocad 2017 LT ?
