Sketcher Basics — From 2D Shapes to 3D Models

Welcome back to FreeCAD Made Easy! In Part 1, we explored the Start Workbench and got familiar with the interface. Now in Part 2, we dive into the Sketcher Workbench — the true foundation of parametric modeling in FreeCAD.

This episode walks through how 2D sketches become fully editable 3D models using the powerful combination of Sketcher and the Part Design Workbench. You’ll learn how to create and control geometry with precision, then transform it into solid features using industry-standard parametric workflows.

🔧 What you’ll learn in this tutorial:

Creating a parametric body and starting a sketch
Choosing sketch planes (XY, XZ, YZ) for proper model orientation
Drawing basic geometry: rectangles, circles, and profiles
Applying constraints (dimensional and geometric) to fully define sketches
Understanding under-constrained vs fully constrained sketches
Building a perfect square using constraints
Using the Pad tool to turn 2D sketches into 3D solids
Introduction to the Pocket tool for cutting features (preview of Part 3)
Working with external geometry and construction lines for precision placement

By the end of this lesson, you’ll understand how Sketcher and Part Design work together to create clean, fully parametric models that can be edited at any stage — a core concept behind modern CAD design.

Whether you’re new to CAD, exploring 3D printing, or looking to improve your workflow in FreeCAD 1.0, this tutorial keeps things simple, practical, and beginner-friendly — no unnecessary complexity, just solid fundamentals that actually stick.

The Pocket Tool

In Part 3 of FreeCAD Made Easy, we take the next step in parametric modeling by diving into the Pocket Tool — one of the most powerful and versatile features in the FreeCAD Part Design Workbench.

This tutorial focuses on how to remove material from a solid model using sketches, allowing you to create holes, cutouts, and detailed features with precision and control. Building directly on the Sketcher fundamentals from Part 2, you’ll learn how to turn fully constrained sketches into functional design features.

🔧 What you’ll learn in this tutorial:

How the Pocket tool works in parametric modeling
Creating cut features from sketches attached to faces
Understanding Pocket types: Through All, To First, Up to Face, and Dimension
Using external geometry to align features accurately
Applying constraints to position holes and cutouts precisely
Best practices for clean, stable feature design in Part Design

Whether you’re designing parts for 3D printing, building mechanical components, or just getting started with CAD, this lesson keeps things practical and easy to follow — no fluff, just real skills you’ll use.

By the end of this video, you’ll have the confidence to carve out complex details and take full control of your models using FreeCAD’s parametric workflow. Continue the series to keep leveling up your design skills.

Multiply Features with Clone, Mirror, Polar & Linear Tools

In Part 4 of FreeCAD Made Easy, we step into one of the most powerful workflow boosters in FreeCAD — the MultiTransform Tool in the Part Design Workbench.

This tutorial shows how to combine multiple transformations—like Mirror, Linear Pattern, and Polar Pattern—into a single operation, allowing you to duplicate and position features quickly while keeping your model clean and fully parametric.

🔧 What you’ll learn in this tutorial:

How to use the MultiTransform tool in Part Design
Applying Mirror features using planes and reference geometry
Creating Linear and Polar patterns from existing features
Understanding order of operations (why sequence matters)
Using Datum planes and references for accurate placement
Building complex geometry from a single feature

Instead of recreating the same feature over and over, MultiTransform lets you work smarter—design once, then reuse it with precision. This is a key step in moving from basic modeling to efficient, professional workflows.

Whether you're designing for 3D printing, mechanical parts, or structured layouts, this lesson will help you speed up your process and keep your models flexible and easy to edit.

By the end of this part, you’ll be able to take a single idea and multiply it across your design—cleanly, efficiently, and fully under control.

VarSets vs Spreadsheets — The Rise of Parametric Control

In Part 5 of FreeCAD Made Easy, we explore VarSets — the modern way to manage parameters in FreeCAD. This is where parametric modeling starts to feel truly powerful, flexible, and streamlined.

This tutorial introduces VarSets as the evolution of traditional Spreadsheet-driven workflows, showing how to control dimensions and relationships directly inside your model without relying on external tables.

🔧 What you’ll learn in this tutorial:

What VarSets are and how they work in FreeCAD
How they compare to Spreadsheets (and when to use each)
Creating and editing parameters directly in the model
Driving dimensions like diameter, spacing, and layout using expressions
Accessing VarSets through the Model tab and Expression Editor
Using parameters in real-world modeling scenarios

VarSets bring parameters closer to where they belong — inside your design — making models easier to manage, understand, and modify. It’s a cleaner, faster workflow that reduces complexity while increasing control.

Whether you're building parametric parts for 3D printing, refining your CAD workflow, or just trying to make your designs more adaptable, this lesson shows how to take control of your model in a smarter way.

By the end of this part, you’ll be able to drive your designs with variables instead of guesswork — and that’s where FreeCAD really starts to shine.

Why Won't it Move?

Struggling with constraints in FreeCAD? You’re not alone. Constraints are one of the biggest challenges for beginners—but they’re also the key to creating clean, fully parametric models.

This FreeCAD Made Easy lesson focuses on how constraints really work inside the Sketcher Workbench. You’ll learn how to control geometry, eliminate degrees of freedom, and understand why sketches break—or behave unpredictably—when constraints are missing or applied incorrectly.

In this tutorial, you’ll learn:

How geometric and dimensional constraints work
What under-constrained vs fully constrained sketches mean
How to fix sketches that move or behave unexpectedly
How to use constraints to build stable, editable designs
Why constraints can feel frustrating—and how to make them click

Constraints can be a pain at first, but once they make sense, everything in FreeCAD gets easier. This guide is built to help you push past that frustration and start creating reliable 3D models with confidence.
