Okay this is more of a engineering question then a SW one.  But I am putting together a drawing of a concept but it is extrmely preliminary, and I need to provide it to a client for there internal presentation.  I want to ensure that I lable in some way to state that the drawing is not to be used to make anything or that it is a final drawing in any way.

Is there a "standard" term or sentance that is used for this?
