Autocad new layer AM create by itself?

[francine.zimmermannSRSWJ]

Hello, 

I working with AutoCAD standard 2022 and since a few weeks by doing a hatch a new layer AM is created by itself.

I work with my own company layers, how can I stop this? 

As I know AM ist for mechanical but I don't work with the mechanical application.

Is this a system variable that needs to be modified?

Thanks for your help

I tried to save the drawing (just with a rectangle) under version 2000, and I got a message (see attachment).

Maybe that's the reason?

By doing a purge nothing changes but I tested the "export" command and now, finally, my hatches are created again with the correct layer. To assign the layer to hatch I use a lisp with reactor. I never had that since I work with AutoCAD, I think it's from a block I inserted

this is normal, becouse  A 2022  have futures that did exist in A 2000, so that message was to prevent you that for ex>  Mleader is not suported in A 2000, and automatic will be transfromed in to a block etc...

I found the problem 

I don't know how it happened but the variable HPLAYER was wrong 🤕

Enter new value for HPLAYER, or . for use current <"AM_8">:

I change it to "." and all is fine.

Thank you all for your help

On the keyboard if you punch textlayer you see AM-6 replace AM-6 by a point (.) and it`s fix

Punch TEXTLAYER on the keyboard you see (AM-6) or an other one, replace AM-6 by a point (.) and it fix

Greetings, 

Just to chime in, I had same kind of issue with my office AutoCAD  where whenever I created any dimension it used to create one layer with this 标注 name. Don't know how but I don't know Chinese and Am not dealing with any blocks or other stuff from Chinese company drawings. Maybe this is a virus ...not sure why this layer was created. so I applied the same solution but with the command "DIMLAYER" it was set to this layer so I changed it back to '.' and it resolved the Issue. Nonetheless the creation of that layer is still mystery for me.

Thank you for the solution.

@vishalSF7XZ Layers appearing in a DWG that never had them before is not a virus or corrupt software or much of a mystery really: there are many reasons AutoCAD will do that as part of a user action all day long (think imported blocks, dimstyles, copy/paste and so much more) in addition to many system variables being preset to add those layers when certain commands are activated.

Ask the files creator in your case for guidance: they activated them and can help you deactivate them.
