I need a complete General Arrangement Drawing for a custom‐built heat exchanger that must meet ASME requirements. This is not a standard shell-and-tube, plate, or air-cooled unit; the configuration is unique to the process, so I’m looking for someone who can translate my process data and preliminary sketches into a clear, fabrication-ready layout. The drawing has to indicate all critical overall and nozzle dimensions, support details, lifting points, weld seams, and space envelopes for maintenance. I work in AutoCAD, so a DWG file accompanied by a clean PDF is essential. If you normally add a simple bill of materials and a drawing legend, please include those as well. Acceptance is straightforward: the file opens error-free in AutoCAD 2021, dimensions and notes align with the ASME code sections that govern pressure boundaries, and the sheet is tidy enough for a shop foreman to read without guesswork. If you’ve produced ASME-compliant GADs for unconventional exchangers before, let me see a sample and we can get started.

Hello, I’m very interested in supporting your project by developing a complete General Arrangement Drawing (GAD) for your custom-built heat exchanger. I understand that this is a non-standard configuration, and I have experience translating process data and conceptual sketches into clear, fabrication-ready engineering drawings that can be directly used by workshop teams. My workflow begins with a thorough review of your provided process data, sketches, and any design constraints. Based on that, I will develop a fully detailed GAD that includes all critical elements such as overall dimensions, nozzle orientations and locations, support structures, lifting points, weld seams, and maintenance clearance envelopes. I will ensure the drawing is logically organized, easy to read, and suitable for fabrication without ambiguity. I am familiar with ASME requirements related to pressure boundaries and will align dimensions, notes, and layout practices accordingly to meet expected standards. Deliverables will include: • AutoCAD DWG file (fully compatible with AutoCAD 2021) • Clean, print-ready PDF • Basic Bill of Materials (BOM) • Drawing legend and clear engineering notes I can provide a first draft within 2–3 days after receiving your base files, followed by quick revisions to reach final approval. I focus on accuracy, clarity, and practical usability in all drawings. I’m ready to start immediately once you share your inputs. Best regards, [Mohammed Hussein]

Hi, I produce fabrication-ready General Arrangement Drawings for custom pressure equipment and work directly to ASME BPVC requirements. Relevant experience: Completed ASME-compliant GADs for 3 non-standard heat exchangers in the last 18 months, including a vertical U-bend bayonet and a jacketed spiral unit. All drawings passed client + fabricator review with no redline for dimensioning or code callouts. I translate process data sheets and markups into clean layouts showing overall envelope, nozzle schedule with projections/ratings, support lugs/skirts, lifting trunnions, weld seam locations, and maintenance pull space. Delivery & standards: AutoCAD 2021 native DWG + vector PDF. Drawings use standard layer/CTB setup, model space 1:1, paper space viewports. All dimensions and notes reference ASME BPVC Section VIII Div 1 for pressure boundaries. I include a drawing legend, BOM stub for major components, and a clear note block. Files open error-free in 2021 and plot clean for shop use. Workflow: I'll review your process data + sketches, issue a nozzle/orientation plan for approval, then complete the CAD with one comment round included.

Thanks for considering my profile for your exclusive project designing a custom-built heat exchanger! While my career leans towards building facades, the set of skills I've acquired over time specializing in 3D Drafting, AutoCAD, and Engineering Drawing, transcends that niche. Dedicating myself to producing high-quality, marketable designs on-time while maintaining rigorous standards aligns perfectly with the ASME requirements and meticulousness your project demands. My experience producing feasible architectural plans has developed in me a unique ability to understand complex process details and convert them into clear and read-worthy designs. This proficiency is amplified by my strong command over AutoCAD, which allows me to confidently organize precise dimensions, nozzle placements, weld seams, lifting points - all ensuring a fabrication-ready DWG file alongside a clean PDF. Ultimately, I consider not just design aesthetics but also implementability and convenience when creating architectural designs. So you can rely on me to accurately present all critical overall and nozzle dimensions, support details and space envelopes for maintenance - facilitating seamless fabrication procedures. Prioritizing your satisfaction above all else, I commit to produce an ASME-compliant GAD with a cleaning PDF that opens without errors in AutoCAD 2021.
