SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Creating and modifying parametric 3D CAD models normally requires manual GUI work in FreeCAD. This Skill lets an agent drive a running FreeCAD instance programmatically to model parts and assemblies, edit object properties, run FEM analysis, and export engineering files. ## Core Features & Use Cases - Parametric modeling: Create and edit document objects (Part, PartDesign, Draft), insert parts from a library, and set placement, scale, and rotation with verification via get_object and get_view. - Import/export and reporting: Import and export STEP, STL, OBJ, and DXF files, and generate PDF or Excel reports from a model. - FEM analysis: Run CalculiX-based finite-element analysis on a Fem::AnalysisPython container, returning max von Mises stress, displacement, and node count. - Use Case: Ask the agent to design a bracket, apply fixed and force constraints, mesh it with Gmsh, run a FEM analysis, and export the result as a STEP file plus a PDF report. ## Quick Start Use the FreeCAD skill to create a parametric bracket model, verify its geometry, and export it as a STEP file to the exports directory.

Frequently Asked Questions about qwen-mm-plugins-freecad

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create parametric 3D models in FreeCAD programmatically?▼

Call create_object to add Part, PartDesign, or Draft objects to the document, then refine properties with edit_object and verify with get_object. For custom operations, execute_code runs Python directly inside FreeCAD's GUI thread.

How do I run FEM analysis in FreeCAD with CalculiX?▼

Create a solid geometry, a Fem::MaterialCommon, a Fem::FemMeshGmsh mesh, and at least one ConstraintFixed plus one ConstraintForce or ConstraintPressure, all added to a Fem::AnalysisPython container. Then call run_fem_analysis, which requires the CalculiX ccx solver on PATH.

Does FreeCAD automation work on macOS or Windows?▼

The automatic FreeCAD download and launch only supports Linux-x86_64. On other platforms you must install FreeCAD yourself and optionally set FREECAD_BINARY to point at the binary before the tools can connect.

Why can't the FreeCAD tools connect to the application?▼

Connection failures usually mean FreeCAD is not running with the FreeCADMCP addon, or a headless machine lacks a virtual display such as xvfb. The tool error message identifies the cause, and --check-system from a source checkout lists missing system tools.

When should I use execute_code versus execute_code_async in FreeCAD?▼

Use execute_code for anything touching documents, objects, FreeCADGui, selection, or recompute, since it runs on the GUI thread. Use execute_code_async only for long pure OCCT or CPU computations that do not touch the GUI or document tree.
