Shapr3D: Sketching fundamentals

Sketching is where every 3D model begins. In this 8-part series, CAD educator Claas Kuhnen walks you through the fundamental sketching tools in Shapr3D, giving you the precision, flexibility, and control to build models the right way from the start.

You’ll learn how to set up and position sketches on the right planes, work with constraints to keep your geometry stable, and use splines to capture complex curves with accuracy. You’ll also explore how Shapr3D’s design history lets you make edits that ripple through your model in real time, so changes at the sketch level update your 3D geometry automatically.

Each lesson is built around a core skill: understanding sketch planes, applying geometric and dimensional constraints, drawing with intention, and knowing when a sketch is truly ready to be used as the foundation for a 3D feature. These aren’t isolated techniques. They’re the building blocks of a reliable, repeatable modeling workflow.

By the end of the series, you’ll know how to create sketches that don’t just look right. They behave right, adapting to your design as it evolves.

This series is for anyone new to CAD or to Shapr3D, with no prior experience required. Each lesson is short, focused, and directly applicable to real modeling workflows. Whether you’re just getting started or building on basic familiarity, this series gives you a solid foundation to work from.
