Comprehensive Guide to Changing the Size of an Object in Fusion 360: Optimize Your 3D Modeling Skills

Fusion 360 is a versatile cloud-based CAD (Computer-Aided Design) tool from Autodesk that combines both parametric and direct modeling techniques. Its capabilities extend to CAM (Computer-Aided Manufacturing), CAE (Computer-Aided Engineering), and more. Fusion 360 is often favored for its user-friendly interface and extensive toolset that supports the complete design process, from conceptualization to production.

How to Change the Size of an Object in Fusion 360

There are two primary methods to change the size of an object in Fusion 360: direct modeling and parametric modeling. Let’s explore each method in detail.

Using Direct Modeling

  1. Open Fusion 360, then select the object you want to resize.
  2. Navigate to the ‘Modify’ menu and select ‘Scale’.
  3. Click on the ‘Entity to Scale’ option and select the entity you want to change.
  4. You can either enter a specific scaling factor or select a point to scale about.
  5. After making the necessary adjustments, click ‘OK’ to apply the changes.

Note: Direct modeling is an intuitive way to resize objects in Fusion 360. However, it’s essential to remember that changes made with this method may not be easily adjustable later, as Fusion 360 won’t keep a record of these modifications in the timeline.

Using Parametric Modeling

  1. Open Fusion 360, then select the sketch or feature you want to resize.
  2. Navigate to the ‘Change Parameters’ option under the ‘Modify’ menu.
  3. You’ll see a list of all the parameters associated with your design. These include dimensions, angles, and other attributes.
  4. Locate the parameter you wish to change, click on its value, and enter the new measurement.
  5. Confirm your changes by clicking ‘OK’.

Note: This method allows you to maintain a history of all changes, making it easier to revert or adjust previous modifications. This is particularly useful for complex designs where maintaining the relationships between different elements is crucial.

Common Pitfalls and Troubleshooting

When resizing objects in Fusion 360, you might run into a few issues. Here are some common pitfalls and solutions:

  • Inconsistent Scaling: This can happen if you’re not scaling from the object’s center. Always check the ‘Point to Scale About’ option to ensure you’re scaling from the correct point.
  • Unable to Edit Parameters: This might occur if you’re working with imported models that do not have a parametric history. In such cases, consider using the direct modeling approach.
  • Distorted Objects After Resizing: This usually occurs when scaling non-uniformly, leading to distortion. Ensure you’re applying the same scale factor to all dimensions to maintain the proportions.

Advanced Tips and Tricks

  • Use ‘User Parameters’ to define a set of measurements that you can quickly apply across your design. This is especially helpful when you need to maintain certain proportions or work with standard dimensions.
  • When working with complex assemblies, make sure to isolate the part you’re scaling to avoid unintentionally changing other components.
  • For finer control over the scaling process, consider using the ‘Press Pull’ tool under the ‘Modify’ menu. It allows you to directly adjust the size of faces, features, or bodies.

FAQ: How to change the size of an object in fusion 360?

1. How do you resize an object in Fusion 360?

To resize an object in Fusion 360, you can use either the Scale tool under the ‘Modify’ menu for direct modeling or the ‘Change Parameters’ option for parametric modeling. For direct modeling, select the object you wish to resize, select ‘Scale’, define your scaling factor, and apply the change. For parametric modeling, you’ll need to adjust the relevant parameter in the ‘Change Parameters’ dialog box.

2. How do you resize an object in fusion?

Resizing an object in Fusion 360 can be achieved either through direct or parametric modeling. The Scale tool available under the ‘Modify’ menu is handy for direct resizing. For parametric resizing, use the ‘Change Parameters’ dialog to adjust your chosen feature’s parameter value.

3. How do I change the size of the rectangle in Fusion 360?

To change the size of a rectangle in Fusion 360, open the sketch that contains the rectangle, then use the ‘Sketch Dimension’ tool (represented by an “A” next to a ruler in the sketch dropdown menu) to redefine the lengths of the rectangle’s sides. Click on a side, then click again where you want to place the new dimension and type in the desired length.

4. How do you center an object in Fusion 360?

To center an object in Fusion 360, you’ll want to use the ‘Align’ tool under the ‘Modify’ menu. First, choose the point or face of the object you wish to center, then select the target point or face you want to align it to. This tool allows you to align objects along any axis, providing great control over your design.

5. How do you make components smaller in Fusion 360?

To make components smaller in Fusion 360, you can use the ‘Scale’ tool found in the ‘Modify’ menu. Once you select the tool, click on the body you want to resize and specify your scaling factor. A scaling factor less than 1 will make the component smaller.

6. How do you scale a DXF in fusion?

To scale a DXF file in Fusion 360, first, import the DXF file into a sketch. Once the DXF file is in your sketch, use the ‘Scale’ tool in the ‘Modify’ menu to resize it. You can either specify a scaling factor or use the bounding box to interactively scale your design.

7. How do you access preferences in Fusion 360?

You can access the Preferences dialog box in Fusion 360 by clicking on your username in the top-right corner of the application window, then selecting ‘Preferences’ from the dropdown menu. This will open a dialog box where you can customize various settings to suit your needs.

8. How do I know the size of my Fusion 360?

To determine the size or dimensions of an object in Fusion 360, use the ‘Inspect’ tool. This tool, found under the ‘Tools’ menu, allows you to measure distances, angles, and other properties of your object. Simply select the elements you want to measure, and Fusion 360 will display the results.

9. How do you extrude an angle in Fusion 360?

To extrude at an angle in Fusion 360, use the ‘Extrude’ tool and select the profile you want to extrude. In the dialog box that appears, select ‘Angle’ from the ‘Direction’ dropdown menu, then input your desired angle and distance for the extrusion.

10. How do you center something in fusion?

Centering an object in Fusion 360 can be done using the ‘Align’ tool under the ‘Modify’ menu. Select the feature you want to center, then select the target point or face you want to align it with.

11. How do you move a body to a different component Fusion 360?

To move a body to a different component in Fusion 360, right-click on the body in the browser, and select ‘Move/Copy’. In the dialog box that opens, select the new target component under ‘Parent’ and click ‘OK’. The body will now be part of the new component.

12. How do you scale an entire assembly in Fusion 360?

Scaling an entire assembly in Fusion 360 involves using the ‘Scale’ tool. First, create a new component to contain the entire assembly. Then select the new component and use the ‘Scale’ tool to resize it. This will scale all bodies and components within the new component proportionally.

13. How do you scale a whole assembly in Fusion 360?

Similar to scaling an entire assembly, scaling a whole assembly involves using the ‘Scale’ tool in the ‘Modify’ menu. You need to first create a new component that contains all the bodies and components you want to scale. Then, select this new component, and use the ‘Scale’ tool to resize it as desired.

14. Does Fusion 360 support DXF files?

Yes, Fusion 360 supports DXF files. You can import DXF files into a sketch in Fusion 360 by using the ‘Insert DXF’ option in the ‘Insert’ menu. This allows you to work with 2D drawings and designs made in other CAD programs.

15. Can you scale a drawing in Fusion 360?

Yes, you can scale a drawing in Fusion 360. In the drawing workspace, select the ‘Scale’ option from the ‘Sketch’ dropdown menu. Then, click on the drawing you want to scale and specify your scaling factor to resize it. Note that scaling a drawing will change its proportions, so use this tool carefully.


Mastering how to change the size of an object in Fusion 360 can significantly enhance your 3D modeling skills. By understanding and applying both direct and parametric modeling techniques, you can make your design process more efficient and flexible. Happy modeling!
