Process diagram made easy with PTCAD Plus - P&ID Lite

         P&ID stands for Piping and Instrumentation Diagram. It is a detailed diagram in the process industry that shows the piping and related components of a physical process flow. These diagrams are essential tools used in engineering design and plant operation.

Key Elements of a P&ID

A P&ID typically includes:

- Pipes and fittings (with sizes, types, and specifications)
- Valves (manual, automatic, pressure relief, etc.)
- Instrumentation (pressure gauges, flow meters, sensors, transmitters)
- Control systems (PLC, DCS, and their logic interfaces)
- Equipment (pumps, compressors, tanks, heat exchangers, reactors)
- Flow directions and connection points

 Purpose of a P&ID

Design Documentation: Helps in visualizing how the system will work.
Engineering & Construction: Guides installation and maintenance teams.
Operations: Used by operators for understanding and troubleshooting systems.
Safety & Compliance: Critical for hazard and operability studies (HAZOP).

        PTCAD plus edition provides module help user draw P&ID Diagram easily called P&ID Lite. Not only lines and industrial symbols, P&ID Lite attachs data to each symbols inserted to drawing. This mean after user draw P&ID diagram, user will get equipment report data can be view in PTCAD and also able to export to MS Excel file.

        Kindly refer to the example video as a guideline for using the software.

        To load Sheet Metal module , pls select PTCAD Plus Tool then press OK
        At       Plus Tools  menu   user will see ribbons as image

      

Click at  Sheet Metal

     Program will show dialog to select sheet metal geometry to generate unfold production drawing as listed

• Cone
• Cylinder
• Rectangle Transform or Resize
• Three Ways Cylinder
• 90 Degree Cylinder Elbow
• Duct Transform

    User can select  gemetry and input dimension of gemetry then press OK to generate unfold or part production drawing  by specify insertion point of drawing .

    

                        User can print 1:1 scale to cut steel sheet to fabricate wanted gemetry.

FREELISP : Align circles in x or y axis

               

            If user want to make group of circles  align with reference one in X-axis or Y-axis.  Pls download LISP source code and run in your PTCAD.  Video below show how to use command (axy).

    Here is Video

            (setq idx (1+ idx))
          )
          (princ "\n✅ Circles aligned successfully.")
