About Using External Simplified Representations
Often, a large piping project involves multiple engineers. You can use external simplified representations to set up a work environment of only the required piping subassemblies and reference components. Exclude irrelevant subassemblies and include the relevant piping assemblies, equipment, and structure assemblies. You can set subassemblies that are not part of the piping assembly to reference only.
Consider the following factors when using external simplified representations in Piping:
Pipe solids and fittings should not be individually excluded from an external simplified representation. This could cause failure of downstream piping operations. Instead, consider excluding the parent assembly.
You cannot select references from excluded subassemblies when creating pipelines.
When using a schematic to drive the piping, make all needed parts and subassemblies available as references in the external simplified representation.
