DRAWORDER keeps changing

so, I have a raster image underlay in my drawing and I set the DRAWORDER to BACK in order to trace over. The problem is, when I do certain commands, like for instance, merge layers, or move something, it undoes the draw order and the image moves back to the front in a seemingly arbitrary way.

The question would be, how do I set it so it stays in the back no matter what new layers I add or if I move something or delete something, etc. I just want it to stay put.

any ides?

Try pitting it on its own layer and lock that layer. It'd may work

Is the draw order actually changing? Do you REGEN when this becomes apparent?

You should check your DRAWORDERCTL system variable setting, and adjust it, as per the screen capture.

I believe that the default value out of the box is , perhaps your setting has been changed.

Dana's suggestion (REGEN) should reinstate the desired draworder display in your drawing.

I didn't check it, but Dipali's suggestion also seems like a good viable alternative.

Interested to try this variable tommorrow have background image, then a wipeout then linework, must send to back in order and other trick is linework is at elev 1, else wipeout does just that.

This is a problem I often have also. I will have to try your suggestions Dipali & Dadgad in the future.
