Using Include 3D Geometry in the Project command

Fusion's sketching environment holds a powerful tool called "Include 3D Geometry." This command is often overlooked, but it lets you project complex 3D shapes right into your 2D sketches. This ability opens up new ways to design more intricate and accurate parts. We'll look at how this command goes beyond regular flat projections. You can use existing 3D data to build new geometry.

What is "Include 3D Geometry"?

This command lets you project 3D geometry directly into your sketch. Normally, when you project something, it gets flattened onto your sketch plane. However, "Include 3D Geometry" keeps the geometry in its 3D state within the sketch. You'll see purple lines appear, showing the projected 3D form.

How it Differs from Standard Projection

Think about projecting a cylinder. A standard projection would flatten that curve into a circle or ellipse on your sketch. But, "Include 3D Geometry" will show that curve as it exists in 3D space within your sketch. This preservation of 3D form is what makes it so useful.

Let's see how you can use this command to make cool-looking ribs or ridges on a part. This shows you how to use projected 3D geometry to guide new design elements.

Step-by-Step: Projecting Cylindrical Features

Start by creating a sketch on a face of your part. Then, go to "Create" and select "Project." Choose "Include 3D Geometry." Click on a face. You will see purple lines appear, indicating the 3D projection.

Creating Construction Planes for Sketching

Sometimes, you need to sketch on a plane that isn't standard. You can create a new plane that cuts through the projected 3D geometry. Use the "Construct" menu and select "Plane Through Three Points." Pick three points along the projected geometry. This creates a new sketch plane at an angle.

Sketching and Constructing Ribs with the Pipe Command

Now, create a sketch on this new construction plane. You can use the "Project" command with the "Intersect" option. Hover over the cylinder to capture where it meets your sketch plane. This creates a precise line. You can then use the "Pipe" command on this line to create a rib. Add fillets to the ends for a polished look.

Tips for Effective Use of "Include 3D Geometry"

To get the most out of this command, a few tips can help. Managing what you see on screen is important. Combining tools also makes designs more complex.

Combining with Other Sketching Tools

Don't be afraid to mix and match tools. Use "Include 3D Geometry" with the "Intersect" command. Add constraints to your sketches. Combine it with other sketch creation commands. This allows for more intricate designs.

Iterative Design and Refinement

Design is often a process of trial and error. "Include 3D Geometry" makes it simple to adjust your designs. You can quickly modify based on existing 3D data. This helps you refine your models efficiently.

Conclusion: Unleashing Your Design Potential

The "Include 3D Geometry" command is a powerful asset in Fusion. It helps you create complex and detailed designs. It allows for greater precision and aesthetic appeal.

Try using "Include 3D Geometry" in your own projects. Experiment with its capabilities. You might discover new and exciting ways to design. Have fun learning Fusion!
