Ran again here exactly what is being done,
Basically that I am applying material to only a face on a wall object, and when I close out program and restart its not on the wall face, Im not having an issue with applying materials to layers just faces

So picture a 3D IMAGE of a wall, color is then added to various walls in the 3D rendering of a room then saved. Then when computer laptop is restarted all those colors saved are then gone like it was never done.

I thought you said materials were disappearing.  Now you are talking about colors?  Colors of particular materials?  I think a better explanation is in order.

Since you said this has happened in similar drawings I'm guessing it is something you are doing and not necessarily something AutoCAD is doing on its own.

The only real way to see to the heart of the matter would be to attach an actual drawing file to a subsequent post.  Maybe someone here can take a look at it and figure out what exactly is or isn't happening.

Yes very frustrating! So bits a 3D image in which color is added then once saved , and the lap top restarted the work done disappears

Ah...you're back.

What settings are you talking about?

Think about it for a moment.  You've created a drawing and added some materials then you saved the drawing.  Later on you open the drawing and the materials have vanished?  Honestly, something about that just doesn't make any sense.
