I need a precise, engineering-grade 3D model of an oilfield choke manifold that my well testing team can use as a technical reference. The expectation is a full-feature, production-level representation—bolts, valves, tees, flanges, trim, instrumentation ports, the lot—so our engineers can review clearances, match connection sizes, and run basic clash checks before fabrication. Please build the assembly in your preferred CAD package and supply the native file plus a clean STEP export. I’ll also need an isometric render (high resolution, neutral background) that I can drop straight into a slide deck for an internal design review. To make this genuinely useful, dimensions must follow API standards, component tags should be logically named, and all moving parts must sit on the correct axes so we can animate valve operation later on. If you already model with pressure class color codes, keep them in; otherwise a simple grey steel material is fine. When you send the first cut, we’ll run through a quick check against our P&ID to confirm valve count, choke arrangement, and spool lengths. After revisions—usually one or two rounds—you’ll package the final STEP, the native CAD file, and the rendered isometric. That’s it. If you’ve designed wellheads, blowout preventers, or manifold skids before, your experience will translate perfectly here, and we can move fast.
