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=[, ]
)
