acad 13 layers question

Anonymous — Wed, 22 Aug 2018 10:42:16 GMT

Hello.

Can i ask you, how i can change many layers information to one layer. Without no changes colour, linetype, etc.

I have old acad drawing map and i want move all that layers information from one layer. Then i want delete old layers.

Is it possible?

best wishes

Hi,

If an object is set to use color = "byLayer" and you change the object from a green layer to a red layer then the color of that object changes.

If you combine a red layer and a green layer to a black layer (that's how I understand your question) then you first need to change the object to use color not "byLayer" and then you can combine the layers, but that is not a function built into AutoCAD, you might find tools that may handle color, lineweight, linetype, transparency, plotstyle in that way.

May I ask why you combine multiple layers (which means the file has a structure) to one layer (which then means the file lost it's structure)? Where is the advantage of killing a structure?

Hi,

1. You can save the layer on command LAYERSTATE > select all layer properties to restore > export.

2. To another cad command LAYERSTATE > import > restore

3. layer can be delete (if not used) purge or Using CAD Standard.

Can you clarify what version of AutoCAD you are using? R13 is ancient and cannot do what many of the newer versions can do. If you are referring to AutoCAD 2013, you could look into the LAYMRG command.

LAYMRG command works well, just run this lisp in your file first (see attached)

LAYMRG is not what you want, if I understand correctly. You want [I think] something that's red because it's of ByLayer color on a red Layer to remain red when it goes to the one Layer, and something of Dashdot linetype because it's of ByLayer linetype on a Dashdot-linetype Layer to remain of Dashdot linetype when it goes to the one Layer. I assume you also want anything that has any overrides of such properties to retain them after the transfer.

I wrote BEL0CL.lsp, available >here<, to do that to all the pieces in Block definitions. The name stands for Block Entities to Layer 0, maintaining every entity's Color and Linetype [from its original Layer or any override(s)]. It could be adjusted pretty easily to put things on a different Layer than 0, and outside any Block definition. Are you capable of doing that adjustment?

There's another later on that thread that does it also to the entities in Nested Blocks [with an N added in the file name], if that's of interest.
