Subject: Urgent: Cannot Export Multiple Bodies/Components to Single 3MF/STL File (Consistently Fails)
Hello Fusion 360 Community and Support Team,
I'm facing a critical and persistent issue with exporting multiple separate bodies or components into a single 3MF or STL file from Fusion 360. This problem has been ongoing for some time and affects all my designs.
The Problem:
When I use the "3D Print" export function:
* I select multiple distinct bodies or components (e.g., I've tested with 3 simple, separate cubes).
* The export dialog correctly shows "X selected" (e.g., "3 selected").
* However, the resulting 3MF or STL file, when opened in any slicer (e.g., Anycubic Slicer, Cura), consistently contains only one of the selected objects, or fails to include all parts as separate entities. The other objects are simply missing from the exported file.
What I've Already Tried (Troubleshooting Steps):
* Simple Models: The issue occurs even with basic, newly created geometric primitives (e.g., 3 separate cubes in a new, empty design).
* No Geometric Contact: The bodies are physically separated in the design, so it's not an issue of them touching or merging.
* Export Methods: I've tried both directly saving the STL/3MF file (unchecking "Send to 3D Print Utility") and attempting to send it to the slicer utility.
* Component Structure: I've organized my bodies into a single parent component and tried exporting the entire component.
* Full Reinstallation: I have completely uninstalled and reinstalled Fusion 360.
* Reset Settings: I have also reset all local Fusion 360 user settings and cache.
My Goal:
I need to export multi-part assemblies (like a Yo-Yo with its inner bearing/spacer) as a single 3MF/STL file, ensuring all components are preserved with their precise relative positioning for accurate 3D printing.
This is preventing me from proceeding with my projects. Has anyone encountered this specific issue before, especially where it persists after a full reinstall and reset?
Any guidance or potential solutions would be greatly appreciated.
Thank you.
