The Work
You will create and review parametric CAD data for AI model training. The work involves practical mechanical design, accurate FreeCAD models, dataset generation, and clear documentation.
You will build reusable digital representations of mechanical parts, assemblies, and design features while checking that each model is accurate, robust, and suitable for real-world manufacturing.
• Create, edit, and validate precise parametric CAD models in FreeCAD.
• Build a varied library of mechanical parts, assemblies, and design features.
• Apply Geometric Dimensioning and Tolerancing principles to reflect mechanical design standards.
• Review CAD data for geometric accuracy, find discrepancies, and resolve quality issues.
• Apply feedback and make revisions as project requirements change.
• Document modeling workflows and design decisions for technical traceability.
• Use Python scripting where helpful to automate modeling, improve parametrization, and enrich the dataset.
What It Pays And Takes
