Update Fusion 360 and Try Again

March 17, 2022 Post a Comment

Beginners often face up a common issue when trying to mirror objects in Fusion 360.

Several things could exist preventing the mirror command from working. In this post, I'll exist answering the following questions and statements:

Why is the mirror part not activated in Fusion 360?
Why won't my sketch objects select to mirror?
Mirror tool not bachelor to use
Cannot select lines which I want to mirror in mirror command
Tin can't get mirror command to piece of work
Fusion 360 mirror not working

Each problem or question is due in part that there are two different mirror commands. Fusion 360 has a Sketch Mirror control and a Model Mirror Command.

The Sketch Mirror command is to be used only with sketch geometry. Both Fusion 360's native sketch geometry, as well as inserted SVG lines, tin be mirrored.

Contrary, the Model Mirror control is to be used only with faces, 3D bodies, features, and components.

These features do not piece of work with i another. It'southward necessary to pay shut attending to the location and icon of each mirror command.

Fusion 360 Sketch Mirror command icon vs Fusion 360 modeling mirror command icon — Notice the subtle difference betwixt sketch and model mirror commands. This subtle difference often leads beginners downwards the wrong path.

The Sketch Mirror command looks similar two hollow triangles. The original triangle on the left is black, while the mirrored triangle on the right is bluish.

The Model Mirror command looks very similar to the Sketch Mirror command – which is why it'southward so easy to select the wrong one. The Model Mirror control is filled-in. It has a greyness triangle on the left and a blue triangle on the right.

Fusion 360 Sketch Mirror Command

The Sketch Mirror command mirrors the selected sketch curves nearly a selected mirror line.

Of import: You must be in an active sketch environment to utilise the Sketch Mirror command.

Create a new sketch or enter an existing sketch environment.
Activate the Sketch Mirror command from the toolbar or Create dropdown (while in the Sketch tab)

Select all Sketch objects (curves) that you want to mirror. Exist sure to avoid selecting your desired mirror line.

Select the Mirror Line selector in the dialog > Select the desired Mirror line (which can be a construction line)

Select the a mirror line for Fusion 360 to use with the sketch mirror command

Click OK in the dialog

Notice the symmetry constraint icons that are automatically applied after the sketch mirror command is used in Fusion 360

The sketch objects will so be copied. Symmetry constraints will appear adjacent to all sketch objects that have been mirrored. Whatsoever changes to the original side will be automatically updated to the mirror side.

Fusion 360 Model Mirror Command

The Model Mirror command makes a mirrored copy of selected faces, features, bodies, or components at equal distances across a plane.

Of import: The Model mirror control does Non work with Sketch geometry.

Select the Model Mirror control from the Create dropdown

Select the model mirror command from Fusion 360's create dropdown

Select a Pattern Type – Faces, Bodies, Features, Components

Select the pattern type for Fusion 360 model mirror command

Select the Objects selector in the dialog > Select the object(s) based on your Pattern Type

Select the objects selector and select the desired objects to mirror in Fusion 360

Select the Mirror line selector in the dialog > select an origin plane, construction plane, or face to mirror by

Select the mirror line selector and select an origin plane or face to use as the mirror line in Fusion 360

Gear up the Compute Selection – Optimized, Identical, Conform

Set the compute option for the mirror command in Fusion 360

Take note of the Model Mirror control (icon) displaying in the parametric timeline (at the bottom). To edit the mirror control but double-click on the icon in the timeline.

Notice the mirrored body is complete after using the Feature Pattern Type in Fusion 360

Blueprint Types in Fusion 360 Mirror Command

The model mirror command has the post-obit four pattern types. Each pattern type lets y'all select a dissimilar type of object to mirror. Remember, the modeling mirror command is parametric, meaning you lot tin edit the feature at any time – which means you can always change the pattern type selection.

Faces – mirror only the confront(s) of 3-dimensional objects
Bodies – mirror 3D solid bodies or a unmarried body
Features – mirror a model feature or selection of model features in the parametric timeline
Components – mirror component(southward), which tin contain several bodies and other modeling features

Compute Pick in Fusion 360 Mirror Command

The compute selection lets yous cull how the mirror command will be calculated past Fusion 360. The selection selected can impact the performance, as outlined beneath.

Important: If your mirror is not showing up, effort using a dissimilar compute option.

Optimized (fastest) – Just mirrors the faces of the feature, which optimizes operation.
Identical (moderate) – This method just extracts the pattern blazon choice, mirrors that pick, making it identical to the original part.
Adjust (slowest) – This method recomputes each mirror example nearly as if it were a separate characteristic. This allows you to practise alter parts of the mirrored object, and have each example of the mirror compute differently.

Fusion 360 Mirror Best Practices

When possible use the Model Mirror command over the Sketch Mirror command – It's easier and faster for Fusion 360 to render bodies
Avert using either Mirror Command when copying and pasting components provides the desired result
Never mirror threads or other components that piece of work in a singular direction. Call back, they'll be mirrored, causing them to be astern
Use minimal mirror features in a single blueprint file. Otherwise, functioning volition exist profoundly impacted. Considering inserting a component (with mirrors) into a new pattern file (the larger assembly file)
