Mistakes happen in CAD, but the good news is you don’t need to start from scratch. In chapter 1 lesson 9, we’ll show you how to edit and modify 3D parts quickly and efficiently using parametric design, modify tools, and the timeline.

You’ll see how going back to your sketch can update the entire model automatically, and how tools like fillet, chamfer, and shell let you refine geometry directly in 3D. Plus, we’ll explore the timeline, a powerful feature that tracks every step of your design so you can step back, edit features, and fix errors without breaking your model.

What you’ll learn in this episode:

• How parametric design makes updates flow through your model
• Using modify tools like fillet, chamfer, and shell
• Editing features directly from the timeline
• How to fix mistakes without rebuilding your part
