SPOOLFAB PIPING ISOMETRIC DRAFTER — DISCOVERY CALL / EXPLORING A POTENTIAL ONGOING RELATIONSHIP (OIL & GAS FABRICATION) WHAT THIS POSTING IS This is a discovery post, not a bid request. We are not asking for a formal quote, a firm rate, or a committed turnaround time at this stage. We're simply trying to find out whether experienced SpoolFab drafters are out there who'd be interested in exploring an ongoing subcontract relationship with us, and to have an initial conversation about fit, experience, and general capacity before either side commits to anything. If there's mutual interest, we'll follow up with a real scope of work, you'll propose your pricing against it, and we'll provide a small pilot batch to get started. ABOUT THE WORK We are a pipe fabrication shop that bids and builds piping packages for oil & gas well-pad and midstream projects. When we win a package, the customer supplies us with piping isometric drawings (ISOs) as PDF files defining pipe routing, sizes, schedules, materials, fittings, and weld/flange details for each line or spool. Before we can release drawings to our shop floor, every customer ISO needs to be recreated as a native, shop-ready drawing inside SpoolFab, our fabrication drafting software. We're looking to eventually bring on an experienced piping isometric drafter who already knows SpoolFab inside and out, for what we hope becomes an ongoing subcontract relationship — not a single short-term gig. As we continue winning packages over time, we'd want to keep sending new batches of ISOs to recreate, indefinitely, batch after batch. Right now we're just exploring whether that kind of partner exists and is interested, before we formalize anything. WHY SPOOLFAB, AND WHERE SOLIDWORKS FITS IN Our interest in SpoolFab specifically comes down to how easy it is to work in and how low the cost of entry is for a subcontractor — you don't need an expensive seat or a steep learning curve to get productive in it, which matters a lot to us for an ongoing, flexible relationship like this. That said, we also use SolidWorks internally, so if you feel SolidWorks is a viable way to produce the same kind of shop-ready isometric/spool output, and you already hold the necessary SolidWorks license and have genuine interest in this work, please express interest as well — we're open to hearing that case. WHY WE'RE EXPLORING THIS This is real production work that would feed directly into our fabrication schedule. Once a package is awarded to us, we typically have about two weeks before production must begin on the shop floor, so turnaround speed matters a lot to how we'd eventually structure this. We're not asking you to commit to a lead time in this post — we just want to understand, in general terms, whether your availability and experience could realistically support that kind of pace before we go further. WHAT THE WORK WOULD LOOK LIKE, IF WE MOVE FORWARD If this turns into a working relationship, the scope would generally include: 1. Recreating each customer piping isometric — provided as a native, CAD-exported PDF — as a true SpoolFab fabrication drawing, matching the source ISO's pipe size, schedule, material specification, fittings, weld and flange call-outs, and all dimensions exactly. 2. Generating the SpoolFab-native outputs for each isometric under our shop's configuration — spool breakdowns, cut lists, and BOM exports, as applicable. 3. Handling sub-spool breakdowns. After we deliver an initial recreated ISO, we may redline it ourselves to break it down into multiple smaller sub-spools for fabrication or shipping reasons. When that happens, you'd create a separate SpoolFab drawing for each resulting sub-spool as its own line of work. 4. Flagging problems instead of guessing through them. Customer-supplied isometrics aren't always perfect — dimensions can be missing, BOMs can be inconsistent with what's drawn, or a callout can be ambiguous. We'd want any of that flagged clearly with a specific question rather than an assumption pushed through to the shop floor. HOW WE'D EXPECT TO START Rather than throwing a large, unfamiliar batch of live work at a new drafter on day one, we'd want to start with a small pilot batch of maybe 10 to 20 ISOs pulled from packages we've already won and completed in the past. That would let us confirm you can produce clean, correct SpoolFab output matching our shop's conventions, work out file naming and hand-off logistics, and build real trust in turnaround and quality before scaling up to live, time-sensitive batches. None of that starts from this post — it's simply the shape of what would come next if there's mutual interest. HOW WE'D EXPECT TO PRICE THIS, EVENTUALLY We anticipate structuring pricing so it scales fairly with how much work is actually in a given isometric — tiered by the number of line items in that isometric's bill of materials (BOM), roughly: small (1-9 items), medium (10-25 items), and large (26+ items) — plus a separate rate for sub-spool breakdown work created after an initial ISO is redlined for splitting. We are not asking for your specific numbers in this post. If you have a general sense of your typical range for this kind of work, feel free to mention it, but it's optional and non-binding at this stage — we're not comparing bids here. QUALITY EXPECTATIONS, IN GENERAL TERMS Longer term, our approach to quality would be straightforward: if a delivered isometric or sub-spool contains an error you introduced, you'd correct it at no additional charge, since that's a normal part of careful drafting work, not a penalty. That wouldn't apply if the source drawing itself was ambiguous and you'd flagged it before drafting, or if we later redline something that was correctly drafted the first time — both of those would be new work, not free rework. We're mentioning this now just so you know how we think about the relationship, not because we need you to agree to it yet. WHAT WE'RE LOOKING FOR IN THIS CONVERSATION Required: - Direct, hands-on production experience with SpoolFab, OR with SolidWorks if you currently hold your own SolidWorks license and can produce equivalent shop-ready isometric/spool output. AutoCAD, CADWorx, or PPO experience is good background but not a substitute on its own — we need someone already fluent in one of our actual working tools, not someone learning it on our drawings. - Strong isometric-reading fundamentals: pipe specifications, ASME B31.3 and B31.8-style fabrication conventions, weld symbols, flange ratings and classes, and bend/cut data. - Comfort working entirely from PDF source files — we have no native CAD files from the customer to hand you. - Genuine interest in an ongoing relationship rather than a one-off project, since that's what we're ultimately trying to build. Nice to have: - Prior experience on oil & gas well-pad or skid piping packages, since our drawings follow those conventions. - Experience producing shop-floor-ready spool sheets for an actual fabrication shop, not design/EPC-side isometric drafting. WHAT WE'D LIKE FROM YOU RIGHT NOW This is a low-commitment first step for both of us. Please reach out with: 1. Which software you'd be working in — SpoolFab or SolidWorks — and confirmation that you currently hold the license/software yourself and have real, hands-on production experience with it, plus roughly how long you've been using it. 2. A sample of an isometric or spool drawing you've personally produced in that software, if you're able to share one (redact any confidential customer information). 3. A general sense of your current availability and capacity — not a firm number, just whether taking on an ongoing subcontract relationship like this is realistic for you. 4. Whether you'd be interested in a short conversation to talk through how this might work before either of us commits to anything. We're not evaluating applications on price or speed at this stage — we're just trying to find out who's out there, genuinely experienced in SpoolFab or SolidWorks, and open to exploring a long-term working relationship. If there's a fit, we'll define a real scope of work, you'll propose your pricing against it, and we'll provide a small pilot batch to get started.

Hi, Thank you for the detailed posting. I’m very interested in exploring this as a long-term subcontracting relationship rather than a one-off project. My background is in mechanical engineering and CAD, with extensive experience in SolidWorks, 3D mechanical modeling, manufacturing drawings, fabrication documentation, and engineering projects. I am comfortable interpreting technical drawings, dimensions, material specifications, fittings, weld details, and manufacturing requirements. For your workflow, I understand that accuracy is critical because the recreated isometrics will go directly to the fabrication shop. I would follow the customer ISO exactly and flag any missing, conflicting, or ambiguous information rather than making assumptions. I’m particularly interested in your proposed pilot approach of 10–20 previously completed ISOs, as this would allow both sides to establish drafting standards, file conventions, quality expectations, and workflow before moving into live production packages. I’m also interested in developing a long-term relationship where I can provide additional capacity when your project workload increases, including sub-spool breakdowns and revisions. I would be happy to discuss your current workflow, typical ISO complexity, expected monthly volume, and the pilot batch during a discovery call. Best regards,

Hello, I’m a Mechanical Engineer with over 2 years of experience in piping design, AutoCAD Plant 3D, piping isometrics, and industrial projects, with experience across 200+ engineering projects. I can also share samples of my previous piping and isometric work. I’m interested in exploring a long-term subcontracting relationship for your oil & gas fabrication projects. I understand the workflow of taking customer-issued PDF ISOs and recreating them as clean, shop-ready fabrication drawings. My relevant experience includes: - Piping isometric drafting and detailing - Oil & gas and industrial piping systems - Pipe sizes, schedules, materials, fittings, flanges, and weld details - Spool identification and fabrication-oriented documentation - AutoCAD and AutoCAD Plant 3D - BOM/MTO extraction and drawing coordination - Careful checking of dimensions, elevations, welds, and connection details I understand that accuracy is critical because these drawings ultimately go directly to the fabrication shop. I’m comfortable working from customer PDFs, following your drafting standards, and adapting to your SpoolFab workflow after learning your specific procedures and templates. I’m interested in starting with a small pilot batch so you can evaluate my accuracy and drafting quality before establishing an ongoing workflow. I can share relevant piping ISO samples and discuss my experience, availability, and general workflow during an initial discovery call.

Hello, I’m interested in exploring the ongoing subcontract relationship. I’m an experienced CAD designer with strong hands-on experience in SolidWorks, particularly for mechanical fabrication, assemblies, sheet metal, and production-ready drawings. I understand the importance of accurately interpreting piping isometrics, including pipe sizes/schedules, fittings, flanges, weld details, dimensions, BOM information, and spool breakdowns. I’m also comfortable working from PDF drawings and flagging discrepancies or missing information rather than making assumptions. My primary platform would be SolidWorks, and I can produce clean, organized shop-ready spool/isometric documentation. I understand that SpoolFab is your preferred workflow, but given my SolidWorks experience, I’d be interested in discussing whether my workflow can meet your fabrication requirements. I’m particularly interested in the potential for an ongoing relationship rather than a one-off project. My availability can accommodate recurring batches, including time-sensitive production work. I can provide relevant SolidWorks samples and would be happy to have a short discovery call to discuss your workflow, expected outputs, and the pilot batch. Best regards, Adedamola
