The application utilizes a representation rule for each of the views on any of the sheet templates. This representation rule will operate successfully for the sample project as supplied with the product, but may need to be modified to suit your company methodology.
The Representation Library RPLB /Assembly-Planning/RepresentationLibrary contains the Styles and Rules needed for the application to function in its default state.
Each view in the drawing sheet will need to reference a representation ruleset that will determine the colours and line styles of the 2D graphical view. The hierarchy is shown below.

Each view in the sheet templates references the single supplied rule set RRST /Assembly/General/All, which displays model elements using the following rules:
Use /Assembly-Style/PIPE for ALL PIPE WITH (MAT (FUNC OF ZONE, 'Piping' ) NEQ 0)
Use /Assembly-Style/EQUI for ALL EQUIP WITH (MAT (FUNC OF ZONE, 'Equipment' ) NEQ 0)
Use /Assembly-Style/PANE for ALL PANEL
