Hi everyone! It’s Brad Tallis from CAD Ed, bringing you the next installment of the Fusion Getting Started series where we walk through how to create a fishing reel from start to finish. Reference the following video as you follow along:
If you’re new to Fusion, the Sweep command might sound a little intimidating—but it’s actually one of the most useful tools for creating smooth, complex shapes without a ton of extra steps. Think of it like this: you draw a shape (your profile) and then tell Fusion to “drag” that shape along a path you’ve sketched. The result? A clean, continuous 3D feature that follows your design intent.
What is the sweep command in Fusion and why use it?
Sweep is perfect when you want to create things like wires, pipes, rails, or any part that follows a curve. Instead of building multiple features or lofts, the sweep command in Fusion lets you do it in one go. You give Fusion two things:
- A profile (the cross-section of your part)
- A path (the route that profile will follow)
Step 1: Sketch your path
Start with the path—it’s the backbone of your design. Use lines, arcs, or splines to define the route. If your design needs curves, add fillets to keep things smooth. For more complex shapes, turn on 3D Sketch so you can draw in three dimensions.
Step 2: Create a plane for your profile
Your profile needs a home. Use Plane Along Path to create a plane right at the start of your path. This ensures your profile is perfectly aligned and won’t twist unexpectedly.
Step 3: Sketch the profile
On that plane, sketch the shape you want to sweep—a circle for a wire, a rectangle for a rail, or even a hexagon for something more interesting. Fully constrain it so it stays put.
Step 4: Use the sweep command
Go to Create → Sweep, select your profile, then select your path. Fusion will pull that profile along the path and create your 3D geometry. If your path has multiple connected segments, keep Chain Selection turned on so Fusion treats them as one continuous route.
Step 5: Make it yours
Want to change the profile later? No problem—edit the sketch and swap the circle for a polygon or slot. Then update the Sweep feature. You can also add fillets or chamfers after the sweep for a polished finish.
Pro tips: Using the sweep command in Fusion
- Start simple: A circle and a straight path are great for learning.
- Use constraints: They keep your sketches stable when you make changes.
- Avoid sharp corners: Add fillets to prevent errors and make smoother sweeps.
- Name your sketches: It’ll save you headaches later.
The Sweep command is one of those tools that feels like magic once you get the hang of it. It’s fast, flexible, and opens the door to creating parts that look professional without a ton of extra work.
