3D Modelling Moving/Floor Planning

Overview

FreeCAD is a parametric 3D CAD modeler for designing real-life objects of any size, with workbenches for mechanical engineering, architecture, and CAM/CNC workflows including profile operations for contour cutting.²⁵ It targets engineers, architects, makers, and CNC users needing free tools for 3D modeling, simulation, and G-code generation.¹⁴ Key distinctions include its modular workbench system and full parametric history for design edits.

Key Features

Parametric Modeling - Builds editable 3D models with full history tracking for design modifications.
CAM Profile Operations - Creates contour toolpaths for CNC machining based on model faces or outlines.⁵
Arch Workbench - Supports 2D profile tools for architectural and building design.³
Path Workbench - Generates G-code with toolpaths, feeds, and dressups like lead-ins and tabs.⁴
Part Design - Enables feature-based solid modeling with sketches and extrusions.⁷
Simulation - Previews toolpaths and machining operations before G-code export.⁸
Modular Workbenches - Switches between specialized environments for different tasks.
Python Scripting - Extends functionality via macros and custom tools.

Pricing

Plan	Price	Includes
Community Edition	Free	Full feature set including modeling, CAM, and workbenches.

Platforms & Requirements

Runs on Windows 7+, macOS 10.11+, and Linux distributions with 64-bit multi-core CPU, 4GB RAM minimum (8GB recommended), OpenGL graphics, and 1GB disk space.² Complex models demand higher specs like 2GHz+ CPU and dedicated OpenGL 4.0 GPU; partial multi-threading limits performance on intricate tasks.²

Integrations & Ecosystem

OpenCASCADE (geometric kernel)
Import/Export: STEP, IGES, STL, DXF, OBJ
CAM G-code processors
Python API for scripting
CNC simulators
Tool libraries for machining

Alternatives

App	Difference
Fusion 360	Commercial with cloud collaboration; FreeCAD is fully offline and open-source.
Blender	Mesh-focused for organic modeling; FreeCAD excels in parametric solids and CAD precision.
LibreCAD	2D-only drafting; FreeCAD adds full 3D and CAM capabilities.
SolveSpace	Lightweight constraint solver; FreeCAD offers broader workbenches and CAM.

Reputation

FreeCAD is respected for its no-cost access to professional-grade parametric CAD and CAM tools, with strong community support via forums and wiki.⁶ Users praise its versatility across platforms and regular updates, though some criticize partial multi-threading and steeper learning curve for complex assemblies.² It stands out in open-source CNC workflows but lags proprietary software in speed for large models.
