FreeCAD Automation

When to Use

• CAD automation and scripting
• Batch processing of FreeCAD files
• Parametric design and design tables
• Assembly management and constraint solving
• FEM preprocessing and mesh generation (CalculiX / gmsh)
• Drawing generation with automatic dimensioning
• Marine engineering hull design and hydrostatics
• NURBS hull generation from HullProfile stations
• CalculiX FEM structural analysis
• STEP import / volume mesh / INP export pipeline
• Design table batch parametric studies
• Natural language CAD commands
• Integration with OrcaFlex/AQWA workflows

Prerequisites

• Python 3.8+
• FreeCAD 1.0+ (November 2024 release)
• digitalmodel package installed

Python API

Basic Operations

from digitalmodel.agents.freecad import FreeCADAgent

agent = FreeCADAgent()
result = agent.execute_prompt("Create a box 100x50x25mm with chamfered edges")
print(f"Created: {result['object_name']}")
print(f"Volume: {result['properties']['volume']} mm3")

Batch Processing

results = agent.batch_process(
    pattern="*.FCStd",
    input_directory="./models",
    operation="export_step",
    parallel_workers=4
)

See sub-skills for full details.

Parametric Design

agent.parametric_study(
    base_model="hull_template.FCStd",
    parameters={
        "length": [150, 175, 200, 225],
        "beam": [25, 30, ],
        : [, , ]
    },
    output_directory=,
    export_formats=[, ]
)
