CAD Exercise: How to use full round fillet (Blueprint)

Exercise 70

In this CAD tutorial we'll use the features: 

1. Extrude

Definition: The primary tool for turning a 2D sketch into a 3D solid. How it works: You select a closed sketch profile and pull it into 3D space.

• New Body: Creates a solid block.

• Cut: Removes material.

• Join: Fuses new material to existing material. Best for: Creating the base block or "stock" material of your part.

2. Full Round Fillet

Definition: A specific mode within the Fillet tool that replaces a flat face with a completely rounded semi-circle. How it works: Unlike a standard fillet where you type a number (e.g., "5mm"), here you do not type anything.

1. Open the Fillet tool.

2. Change the "Type" from Constant to Full Round.

3. Select 3 Faces:

   • Side Face 1

   • Center Face (the one that will disappear)

   • Side Face 2 The Result: Fusion 360 automatically calculates the exact radius needed to turn that center face into a perfect dome or arch that touches both sides tangentially. Best for:

4. Creating "Tombstone" shapes or arched tops on brackets.

5. Rounding off the end of a strap or a belt link.

6. Why use it? If you change the thickness of the part later, a Full Round Fillet updates automatically to stay perfectly round. A standard fillet (e.g., 10mm) would break or look wrong if the part size changed.
