What you'll learn

  • Understand the fundamental principles behind Extrude, Revolve, and Loft — and develop the judgment to select the right tool for any geometric challenge.
  • Use the Extrude tool to transform 2D sketch profiles into 3D geometry and refine bodies using Shell, Face Offset, and Boolean operations.
  • Create cylindrical and sculpted forms by revolving sketch profiles around an axis using control point splines and constraints.
  • Use the Loft tool to connect multiple profiles and produce flowing, organic transitions that Extrude and Revolve cannot achieve alone.
  • Apply all three tools together in a real design project, combining modeling strategies and managing Design History to reach a finished result.

Course content

2 sections • 5 lectures • 1h 26m total length

  • Introduction to 3D modeling in Shapr3D1:10

    Get an overview of the three fundamental modeling tools, the types of geometry each one is suited for, and the design thinking behind selecting the right tool for a given challenge.

  • The Extrude Tool14:33

    Learn how the Extrude tool works and when to use it. This lecture covers transforming 2D sketch profiles into 3D geometry along a single direction, and refining bodies using Face Offset, Shell, and Boolean operations like Union and Subtract. The lecture closes with an introduction to the Revolve tool, which will be covered in depth next.

  • The Revolve Tool10:28

    Understand when the Revolve tool is the right choice for your geometry. This lecture covers creating sculpted forms by revolving a cross-section around an axis, and using control point splines and constraints to define and refine more complex, expressive profiles.

  • The Loft Tool15:48

    Explore what the Loft tool makes possible that Extrude and Revolve cannot. This lecture covers connecting multiple profiles to create flowing, organic transitions, and working with rails, splines, and G1 and G2 surface continuity to control the result.

Requirements

  • A basic understanding of 3D concepts is recommended; no prior CAD or Shapr3D experience is required.
  • A device compatible with Shapr3D (iPad, Windows, or macOS) with an active Shapr3D subscription or free trial.
  • A basic understanding of your device's operating system and an interest in product or industrial design.

Description

Welcome to 3D Modeling Fundamentals: Extrude, Revolve, and Loft, the starting point for anyone looking to get started with 3D modeling in a professional CAD environment. This course gives you a solid foundation by focusing on the three essential tools you will use across virtually every design project — Extrude, Revolve, and Loft — and teaches you not just how they work, but where and when to apply them. Led by 3D designer and educator Claas Kuhnen, this course is designed for designers and professionals who are ready to move from a foundational understanding of 3D concepts into confident, hands-on practice.

This course teaches you the logic behind each tool and the types of geometry it is designed to solve. You will learn when to extrude a profile along a direction, when to revolve a cross-section to achieve sculpted forms, and when to connect multiple profiles with the Loft tool to produce transitions that neither Extrude nor Revolve can achieve alone.

The course culminates in a full design walkthrough — the modeling of a water bottle — that brings all three tools together. You will work through real modeling decisions, combining techniques and applying the judgment you have built to complete a finished, presentation-ready design.

Who this course is for:

  • Designers and creatives with a basic understanding of 3D concepts who want a practical, project-based introduction to modeling in Shapr3D.
  • Industrial designers and product designers looking to expand their CAD toolkit with a modern, history-based modeling environment.
  • Students and hobbyists transitioning from other 3D tools who want to learn Shapr3D's core modeling workflow through hands-on practice.
  • Professionals exploring Shapr3D for the first time who want to understand when and how to apply Extrude, Revolve, and Loft to real design challenges.
