Introduction

A sheet can contains multiple views.

In this case the view can be considerd like kind of layer

Limitation : Objects placed in different view can't be conencted together 

As of consequence multi view is usualy used for :

• 1 view for P&ID Schema / data (Schema)
• 1 view for review annotations (Review Comment)
• 1 view for background geometry (Background
• 1 view for additionnal drawing geometry (draw)

Multiple views could be used to represent in the same P&ID 2 disconnected portions of the system

Instead of multiple views, you can use single view with layers, see dedicated wiki page.
