Introduction to Parametric Part Modeling in Onshape

Designing 3D parts that are easy to modify and update is a core skill for modern engineering and product design. This text-based course introduces you to parametric modeling in Onshape, the leading cloud-native CAD platform. You will transition from basic sketching to creating fully parameterized 3D models where changes to one dimension automatically update the entire design. You will understand how to structure your design intent so your models remain robust and error-free as they grow in complexity. What you'll learn: - Understand foundational CAD concepts, including coordinate systems, design intent, and the parametric modeling workflow. - Create precise 2D sketches using geometric and dimensional constraints to define shape and behavior. - Apply primary 3D features such as extrudes, revolves, sweeps, and fillets to transform sketches into solid parts. - Configure variables and equations to drive parametric relationships across your entire model. - Manage design iterations using cloud-based version control and collaboration tools native to Onshape. The course starts with fundamental terminology and simple 2D sketching before guiding you through 3D feature creation, parametric design logic, and collaborative workflows. You will practice these concepts through clear, written step-by-step explanations and structured design challenges. This course is designed for beginners with no prior CAD experience, as well as traditional CAD users looking to transition to cloud-based parametric workflows.
