# Parametric FreeCAD model of a machined titanium carabiner body (FreeCAD 1.x ONLY) ## Summary I need an experienced **FreeCAD** user (this is a hard requirement — not SolidWorks, not Fusion 360) to build a robust, fully parametric PartDesign model of a small machined part: the body of an EDC titanium key carabiner, cut by wire EDM from 5 mm plate, then milled (two symmetric 1.5 mm recesses) and drilled. This is NOT a from-scratch design job. The design exists: you get a 1:1 reference DXF for the aesthetics, a complete spec sheet with every functional dimension already measured from the physical product, and a **starter FreeCAD file containing the master skeleton sketch and a parameter Spreadsheet already wired with expressions**. Your job is craftsmanship: trace the silhouette properly (lines + tangent arcs only), build the features in the right order, keep every sketch fully constrained, and deliver a model that regenerates cleanly when parameters change. ## What you receive - Starter .FCStd: parameter Spreadsheet ("Parametros") + master skeleton sketch (gate axis, two anchor holes, nose seat point), fully constrained and expression-driven - Reference DXF in real mm (aesthetic guide; the anchor/nose zone of this DXF is known to be freehand and must NOT be traced — it is rebuilt from the skeleton) - Spec workbook ([login to view URL]): all dimensions, tolerances, criticality, modeling rules - Photo set of the existing product (assembly sequence, gate open/closed, caliper shots) ## Key requirements (full list in the spec workbook) 1. FreeCAD 1.x, single PartDesign Body, all dimensions driven by the provided Spreadsheet via expressions. 2. Feature order mirrors manufacturing: symmetric Pad (5 mm) → recess Pocket from an offset datum plane (Espesor/2 expression) mirrored about the mid-plane → through-all hole Pockets → chamfers/fillets last. 3. Wire-cut silhouette sketch: **lines and arcs only** (no splines), tangent-continuous, fully constrained, exportable as clean DXF for wire-EDM CAM. 4. Functional chain is sacred: two Ø3 anchor holes 5.0 mm apart (±0.05), collinear with the nose seat face center at 35.5 mm — these drive the gate preload of the real product. The skeleton already encodes this; everything else is built around it. 5. A construction-geometry verification sketch showing the gate outline in closed and ~30° open positions (no interference with the interior opening). 6. Decorative hole row (5 × Ø3) spaced by distribution between two endpoints — pitch must never be dimensioned directly, and the count must be editable. ## Deliverables - .FCStd source (clean tree, 0 DoF sketches — include screenshots of the Sketcher solver report) - STEP AP214 - DXF of the silhouette sketch (lines/arcs only) - TechDraw PDF: three views/details grouped by operation (wire cut / milling / drilling) with the tolerances from the spec sheet, critical dimensions highlighted - Acceptance test: I will change Espesor, recess depth, axis orientation and hole diameters in the Spreadsheet; the model must regenerate without errors or manual repair. ## Scope notes - Only the BODY. The gate (the spring clip) is an existing part and is out of scope, but its interface dimensions are in the spec sheet and must be respected exactly. - Confidential commercial product: files must not be shared or published. NDA available on request. ## To apply, please include - Examples of FreeCAD (not other CAD) parametric work, ideally PartDesign + Spreadsheet driven - Your FreeCAD version - One sentence on how you would model the two symmetric face recesses (this tells me you read the brief)

Hi, I would be pleased to develop your EDC titanium carabiner body entirely in FreeCAD 1.x, using a single PartDesign Body with a Spreadsheet-driven parametric workflow, fully constrained sketches, and manufacturing-ready deliverables including FCStd, STEP AP214, DXF, and TechDraw documentation. My approach for the two symmetric face recesses is to create a single Pocket from an offset datum plane driven by the Espesor/2 Spreadsheet expression and then mirror the feature about the model's mid-plane to ensure robust regeneration. Could you please confirm the FreeCAD version used in your starter file? With extensive experience in parametric mechanical CAD, precision manufacturing models, and production documentation, I deliver clean, fully editable models that regenerate reliably when key parameters are modified while maintaining strict dimensional accuracy and organized design intent.

Hi! I have recent FreeCAD experience delivering a parametric housing assembly project using PartDesign with fully constrained sketches and expression-driven dimensions. You can see this work on my Freelancer profile where the client left a review and tipped upon completion. For the symmetric face recesses I would create an offset datum plane at Espesor/2 and use a mirrored Pocket feature driven by the recess depth parameter from the Spreadsheet, keeping the model symmetric about the mid-plane without duplicating geometry. I am running FreeCAD 1.1.1 and am comfortable with Spreadsheet-driven PartDesign workflows, fully constrained sketches with 0 DoF, and clean feature trees.

Hello there! Could you please confirm you're using FreeCAD 1.0/1.x (and the exact version of the starter .FCStd file), and whether you'd like the model to remain fully compatible with the stock PartDesign workbench only, without external workbenches or macros? I have experience creating robust, Spreadsheet-driven parametric models in FreeCAD and can build the carabiner body exactly as specified, preserving a clean feature tree with a single PartDesign Body, fully constrained sketches (0 DoF), expression-driven dimensions, and a manufacturing-oriented feature order. I'll reconstruct the wire-EDM profile using only lines and tangent arcs, rebuild the functional anchor/nose geometry from the provided skeleton rather than tracing the DXF, create the symmetric milling recesses from an offset datum plane referenced by the Espesor/2 Spreadsheet expression and mirror them about the mid-plane, then complete the drilling, chamfers, and fillets while ensuring the model regenerates cleanly under parameter changes. I'll also provide the verification sketch for the gate positions, a clean DXF of the silhouette, STEP AP214, TechDraw PDF grouped by machining operations with critical tolerances, and screenshots confirming every sketch is fully constrained and solver-clean. Would you also like me to include a brief design log documenting the dependency chain and Spreadsheet parameters so future edits remain straightforward and maintainable?
