layer color doesn't stick

[jdfnnl]

I copied a legend of electrical symbols from another drawing and when changing the associated layer color, in time it always seems to snap back to its original color. Any ideas what could be causing this?

Hi,

Can we have this legend as a CAD dwg file for testing?

Hi,

1. AutoCAD and ACAD LT cannot do this by themselves.

2. Which allows the layer color to be changed
Restore Layer State
User-specific extensions and third-party applications

(you are talking about an ACI color (color number 1-255) ?

What is the color you like to stick and to what color is it switching back?

Share  the File with the wrong layer color and we take look.

Are they blocks? You need to change the color properties of the block objects.

Properties like lineweight and color of block objects can be confusing, but this link explains how they work and why pretty well: https://www.cad-notes.com/layer-0-bylayer-and-byblock/

@jdfnnl Never seen that happen with only core AutoCAD content: share with us a DWG file that behaves this way, we all use the same tools you do, we should see it happen to us as well.

When you say copy do you mean xref the legend?

If it’s an xref and you change it’s layer color you have to set visretain to 1 so current layer colors will stick. Otherwise after closing and reopening it’ll snap back to the original xref dwg color.

Here is a dwg of the legend that contains the 'elec' layer, which in my current drawing keeps snapping back to color 152. I have not noticed exactly when this happens, but I still need to manually change it most times I publish to PDF. The legend was simply pasted from another file, not inserted as a dwg reference.

well, without the dwg that you copy & pasted this legend in which has the problem, having the legend dwg won't help.

But may I ask why are you copy & pasting when you should be xreferencing which have multiple advantages:

1. any changes in original legend dwg, all other dwgs with this referenced in would automatically update

2. if you already have a block name in the current dwg like "Lighting fixture" that looks graphically different than what's in the legend dwg and you copy & pasted the legend into it, the "Lighting fixture" will now look different.

3. if you already have a Text Style "ARCH_48" in the current dwg and you copy & pasted this legend into it, the Text Style will change and look like your current dwg.

4. if you already have a Layer called "Elec" with a different Color like 3 in the current dwg and you copy & pasted this legend into it, the Elec Layer Color will change to 3.

I made this change in a new DWG file.

Closed and opened it a few times. Restarted AutoCAD 2023 and opened it. Even tested it in AutoCADLT, ARCH and MECH variants of AutoCAD. Nothing has changed back to "blue" from the Orange I assigned.

So... can you share your destination file here with us too?
