FreeCAD Guides: Create 3D from 2D & Back

Getting Started with FreeCAD

Create Precise 2D Sketches as the Foundation for 3D Models

FreeCAD’s Sketcher Workbench lets you draw 2D shapes with geometric and dimensional constraints, ensuring precision for your designs. This is the first step in creating robust 3D models for engineering, architecture, or hobby projects.

Our guides walk you through creating a fully constrained 2D sketch, transforming it into a 3D object, and generating technical drawings. We’ve tested FreeCAD’s tools extensively to provide clear, beginner-friendly instructions that save time and avoid common errors. Whether you’re designing a simple part or a complex assembly, FreeCAD’s parametric approach keeps your workflow flexible.

Start with our tutorials to learn how to use FreeCAD effectively. Avoid common pitfalls like under-constrained sketches by following our tips, and explore the FreeCAD community for additional support.

Why Choose FreeCAD?

FreeCAD is a Powerful Tool for Parametric Modeling

FreeCAD is an open-source 3D parametric modeler that lets you create precise 2D sketches and transform them into 3D models. Its parametric design allows you to adjust dimensions at any stage, making it ideal for engineers, hobbyists, and educators. With FreeCAD, you can also extract detailed technical drawings for manufacturing, ensuring your designs are production-ready.

Step-by-Step Guide to 2D-to-3D Workflows

FreeCAD’s workflow starts with a 2D sketch, which you can extrude into a 3D model using tools like Pad or Pocket. The parametric system ensures that changes to your sketch automatically update the 3D model, saving time on revisions. The TechDraw Workbench lets you generate 2D technical drawings with dimensions and annotations, perfect for sharing with manufacturers.

In this guide, we’ll cover how to create a simple 3D model, such as a box with a hole, and produce a technical drawing. We’ll also highlight common challenges, like fixing under-constrained sketches, and recommend resources like the FreeCAD wiki and forum for further learning.
