Layers moving in relation to other layers

Hi all

Some layers have started moving out of position or resizing in relation to other layers in my model. This has just started happening, the don’t move far, but on a particular model of a house, I find a chair layer for example, has moved into a wall.

Any suggestions?

Layers don’t move, they are nothing more than visibility tags.
If geometry is moving around then something you are doing is moving it.
If you could supply us with a model displaying the behavior we should be able to see if there is a problem with the model.

Thanks very much. At present I have corrected the geometry, but I am interested to see if it happens again. If it does I will supply the offending model.
