Software features for placing and manipulating components enable users to draw and edit P&IDs more rapidly. For example, the software automatically repairs line breaks when in-line components are moved or deleted. Component grouping enhances placement of commonly used components and provides more global control of symbol attributes. A group of components can be defined for various business or project purposes. For example, in the drawing, instrument engineers might want to give instrument lines and symbols a group name for a specific use (i.e., “odor control group”). In this instance, the group name exists only in the drawing for notational purposes and does not have anything to do with the tagging functionality and its stored values. The software’s predefined grouping collections of components or assemblies provide the user the ability to assign logical collections of components for convenient group manipulations.
