Autodesk Fusion September 2026 Update
Autodesk has released the September 2026 major update for Fusion, build v.2705.1.11, delivering one of the broadest sets of improvements the platform has received this year.
The release is not centered around one spectacular headline feature. Autodesk instead improves multiple areas professionals touch every day: modeling reliability, performance, rendering, engineering data, sheet metal, CAM, additive manufacturing, simulation and automation.
That broader direction is increasingly important. Fusion is becoming less of an isolated CAD application and more of the connective layer between concept, engineering, manufacturing and presentation.
Scene Lights Bring Real Lighting Control Into Fusion
P
Point Light
Light radiates outward from a defined location.
S
Spot Light
Focus illumination toward a particular product area.
PH
Photometric
More realistic light distribution for visualization.
Large Designs Get Faster Where It Matters
Some of the strongest improvements in this release are not new commands at all. Autodesk has optimized operations that become increasingly expensive as designs grow in complexity.
30%
Up to 30% faster opening and closing large design files.
55%
Up to 55% faster Select All on large designs.
75×
Up to 75× faster Revolve using Window Selection.
80%
Up to 80% faster configuration assembly updates.
03 / DESIGN + AI
Modeling Reliability and Autodesk Assistant Move Forward Together
More Predictable Lofting
More deterministic mapping for supported closed profiles helps reduce unwanted twisting and unexpected transitions.
Boolean Recovery
Autodesk Rational Mesh Boolean technology provides an automatic fallback for difficult Unite, Intersect and Subtract operations.
Finish with AutoConstrain
Fusion can automatically apply appropriate relationships after a sketch is completed.
Autodesk Assistant
Natural-language bulk property editing pushes AI toward useful engineering-data work rather than novelty.
Product Data, PMI and Sheet Metal Move Closer to Production
More Flexible Product Data
Calculated values such as mass, volume and dimensions can be overridden when real-world engineering data requires it.
Manufacturing Information in Design
Hole/Thread Notes and Leader Notes move critical production information closer to the design model.
More Fabrication Control
Join by Bend, dedicated Fillet and Chamfer tools and improved Corner Closure reduce manual fabrication geometry.
05 / ADDITIVE MANUFACTURING
3D Printing Preparation Gets More Production-Aware
For designers and manufacturers working directly with 3D printing, Additive is one of the most important areas of the September release.
- Expanded Slice Analysis support
- True Shape 2D Packing
- True Shape 3D Packing
- Manual Sub-Nest grouping
- Independent build visibility controls
Better Mesh Handling and More Manufacturing Automation
Mesh Workflows
Combine receives an Enhanced mesh Boolean algorithm, while Remesh gains an Edge Length method for Adaptive and Uniform remeshing.
These tools are especially useful when working between STL files, scans, polygonal geometry and production-ready CAD.
Manufacturing
Manufacturing continues expanding with 2 Axis Part Alignment for supported workflows.
Fusion can also create a milling tool holder directly from imported solid geometry such as manufacturer-supplied STEP data.
07 / PLATFORM
Electronics, Simulation and the Fusion API Keep Expanding
Electronics receives additional schematic and PCB capabilities, while Simulation expands the modern Results experience to Modal Frequencies and Structural Buckling studies.
For developers, the full release of TypeScript support for Fusion scripts and add-ins joins Python and C++ and opens the platform to a wider development ecosystem.
What This Update Means in Real-World Use
01
Less CAD Friction
Faster projects, more reliable lofts, AutoConstrain and Boolean recovery reduce everyday interruptions.
02
Closer to Production
PMI, CAM, sheet-metal, BOM and Additive improvements make the engineering model more useful downstream.
03
AI Gets Practical
Autodesk Assistant begins removing repetitive engineering-data work rather than functioning only as an AI demonstration.
THE BIGGER PICTURE
Fusion Is Becoming a Connected Product-Development Platform
CAD →
CAE →
Electronics →
CAM →
Additive →
Rendering →
Automation
Specialized applications remain essential. ZBrush remains stronger for sculpting, KeyShot for high-end visualization and Maya for animation and complex 3D production.
What Fusion continues to improve is the amount of product development that can happen before those handoffs become necessary.
MGRAFICOS PERSPECTIVE
September 2026 Is Less About One Killer Feature—and More About a Stronger Fusion Everywhere.
This release improves the areas designers and engineers touch constantly: modeling reliability, responsiveness, visualization, engineering data, manufacturing preparation and automation.
The result is a Fusion environment increasingly capable of bridging creative design, engineering and real-world production.
