16.7.1. Multiple Layer

It is always good to create at least one additional layer for use as background purpose. It can contain just one huge rectangular or with some background design with it. It should be separated from the foreground work so that it can be locked within that layer and can be ignored when working on the foreground drawing. Engineer shall consider to have even one more layer for text only if the drawing is complicated, so that text can be animated to be hidden in overview and show only upon zoom in.

Layer Control is at Mid of the Bottom Panel
