Standard vs. Spec Driven P&ID Projects

September 22, 2020 IMAGINiT Technologies

Should you configure the P&ID settings for a Plant project template to be Spec Driven?  We must first understand the differences and ramifications of how Plant 3D will apply them in a project.

Standard P&ID projects

Specifications and Sizes are assigned for P&ID and Plant 3D drawings via Project Setup in a list.

Spec Driven P&ID projects

Specifications are listed from the project spec file directory and size found in them when a project spec file is selected.

 

Specification and Size Properties

The Property type settings for P&ID or P3D class definitions are the same for Standard or Spec Driven P&ID projects.

P&ID DWG Settings – P&ID Class Definitions – Engineering Items – Lines – Pipe-Line Segments

Standard P&ID Project

Standard P&ID projects employ specification and size lists to define the information that can be used in documenting process flows.  Since these lists are independent of the project specifications they can differ.

*The P3D Specification and Size selection lists will display the names of all specifications included in the project and only those sizes included in those specifications.

The P&ID Specification and Size selection lists will display project Specifications and sizes at the top along with the Standard P&ID Project’s specification and size lists below.

Off Spec selections allow designers to start and/or complete project P&ID’s before the P3D specifications have been completed.

While this has the potential to allow incorrect data to be used in the P&D drawings the Validation tools in Plant 3D can be used to monitor for inconsistencies.
