Export Workflow

Overview#

Exporting in Fusion is a family of related commands rather than one button. Which one you use depends on what you are exporting (a whole design, a single body, a sketch, a drawing, a flat pattern, a toolpath) and what you are exporting it to. The most general route is File > Export, which writes the active design to a file on disk or, in some builds, queues a cloud export that you download later. More specific routes exist for meshes, sketches and drawings, and each has its own options.

The key idea of this page is that an export is a snapshot made for a purpose. It is not a save. It does not change your design, it carries only what the format can hold, and it should be regenerated from the master design whenever the design changes.

Where to find it#

The available types depend on your license: IGES export and DXF export through File > Export require a commercial subscription, while every license can export a sketch as DXF. An F3Z (design with external references) cannot be exported as F3D, only as other formats including F3Z.

Step by step#

Exporting a design with File > Export#

1. Finish editing. Make sure the timeline is not rolled back; an export of a rolled-back timeline marker may reflect the rolled-back state. Move the marker to the end (see the parametric design pages).
2. Choose File > Export.
3. In the dialog, set Name (a file name without a path).
4. Pick the Type from the drop-down. The default is usually Fusion Archive Files (*.f3d).
5. Choose the destination. The dialog offers a Save to my computer path and a Browse control, and may default to your Downloads or last-used folder. Verify the path before confirming.
6. Select Export. For large or complex designs, Fusion may process the export in the background and notify you on completion.
7. Open the folder and check that the file exists and has a plausible size.

Exporting a single body or component#

1. In the browser, activate or select the component or body you want to export. For many formats, File > Export operates on the top-level document only; to export a sub-assembly, make it the active component or right-click it for a Save As option (exact behavior varies; verify in your version).
2. If the component is linked to an external reference, consider using Save As into a new design first so that you do not carry along unneeded context.
3. Use File > Export with the relevant type. Many mesh exports let you export only the selected body.

Exporting meshes (Save As Mesh)#

1. Right-click a body, or a component, in the browser and choose Save As Mesh.
2. Choose the Format: STL (Binary), STL (ASCII), OBJ or 3MF.
3. Set Unit Type (for STL especially; the file will not record it, so you must remember it) and Structure: one file or one file per body.
4. Click OK, then choose the file name and location. (Refinement and deviation settings belong to Make > 3D Print and Tessellate, not to Save As Mesh.)

Exporting a sketch as DXF#

1. In the browser, expand Sketches.
2. Right-click the sketch and choose Export DXF. Select the unit (the design unit is the default) and optionally check Points, Projected Geometry and Construction Geometry to include them.
3. Click OK, name the file and save it (Save to a Fusion project is optional).
4. Open the DXF in a viewer or the receiving software and check that dimensions are correct before sending.

Options reference#

What is and is not included#

An export reflects the current state of visible, active geometry, with some caveats that surprise people:

• Hidden bodies and components. Visibility rules vary by format. For some exports, hidden bodies are excluded; for others they are included. Test with a small design and inspect the output, or explicitly turn off the items you do not want exported by checking visibility before you export. Verify in your version.
• Construction geometry. Planes, axes and construction sketches are usually not written to STEP or STL. They may appear in F3D.
• Sketches. STEP and IGES exports of a full design generally do not include sketches (they can include 3D wire or curve data in some situations). Use DXF for sketches.
• Appearances. Colors usually travel with STEP, 3MF and OBJ. Physically based materials do not travel to formats that cannot express them.
• Parameters. Only F3D/F3Z preserve parametric history and named user parameters for use in Fusion.
• Joints and motion. Not preserved in neutral formats. Assembly structure and positions are.
• Mesh bodies. A design that mixes BRep and mesh bodies may export mesh bodies only to mesh formats, or may refuse; test it.

Cloud export and sharing alternatives#

Besides local export, Fusion offers sharing mechanisms that are sometimes better than sending files:

• Share a public link to a design, which provides a web viewer and allows the recipient to download in supported formats. Link behavior and the download options are controlled by project and account settings; verify in your version.
• Invite collaborators to a project, giving them live access to the cloud document with real history.
• Autodesk Viewer displays many formats in a browser for stakeholders who do not need to edit.

Prefer these when the recipient will iterate with you. Prefer file export when the recipient needs an artifact in a specific format for a specific tool.

Tips and pitfalls#

Tip: Name exports meaningfully and include a revision and date: bracket_revC_2026-10-21.step. Receiving a file called Untitled.step in an inbox is a recipe for confusion.

Tip: Re-open your own exports. A thirty-second round trip catches wrong units, missing bodies and lost colors before the receiver does.

Tip: Export a subassembly rather than the entire machine when the receiver needs only a portion. Smaller files transfer faster and expose less intellectual property.

Warning: Exporting an assembly that contains external references may produce a file that includes the referenced geometry, or may reference files that do not exist on the recipient's machine. Test and, if sending F3D, prefer F3Z or STEP.

Warning: Exporting a design with a rolled-back timeline, suppressed features or unsolved errors can produce unexpected geometry. Resolve warnings first.

Warning: Exporting STL in the wrong unit is the most common cause of prints that are 25.4 times too big or too small. Check the slicer dimensions every time.

Practice exercise#

1. Create a design with two bodies: a cube and a cylinder, each in its own component.
2. Export the whole design as STEP. Reopen it and note that there are two components.
3. Hide the cylinder component and export STEP again. Reopen and check whether the hidden component was included.
4. Right-click the cube body and use Save As Mesh to create an STL at High refinement, and again at Low. Compare file sizes.
5. Create a sketch with a circle and rectangle, export as DXF, and open it in a free DXF viewer to measure.

Expected result: you know where each export command lives, and you have learned how your version treats hidden items.
