FAQ
What do you need from me to start the work?
A sketch, PDF, image or a short process description is sufficient then I will review the input and confirm the scope before starting.
Can you redraw an existing P&ID from a PDF or scanned drawing?
I can redraw existing P&ID diagrams from PDFs, scanned drawings into clean and professional AutoCAD drawings.
Which software do you use?
All drawings are created using AutoCAD, following standard P&ID and technical drawing practices.
Will I receive the AutoCAD (DWG) source file?
PDF delivery is included by default. AutoCAD source files (DWG) are available as an optional extra.
Can you follow specific standards or client requirements?
I can adapt drawings to client standards, symbols, tagging conventions and project requirements when provided.
What is the difference between the Basic, Standard and Premium packages?
Basic covers simple P&ID or redrawing tasks, Standard includes detailed P&ID with control loops, and Premium provides complete P&ID documentation with advanced control strategies and control philosophy.
Can you deliver faster if needed?
Extra fast delivery is available as an optional service, subject to project scope confirmation.
How fast can you deliver?
Delivery time depends on diagram complexity and number of loops. Small P&IDs can be delivered within 24–48 hours. Larger or multi-sheet projects require more time. Please message me before ordering for an accurate estimate.
Can you customize the diagram to my company standards?
Yes. I can follow your company template, title block, layer structure, symbols, tagging system, or drafting standards. You may provide examples or guidelines before we start.
Do you follow any standards?
Yes. I use ISA/industrial standard symbols and professional tagging conventions commonly used in EPC and industrial projects.
