Compare Altium Develop vs. Autodesk Fusion
Close All Details Expand All Details
Altium Develop is the full Altium Designer experience, professional schematic, layout, and routing with optional cloud workflows that enhance design without changing how you work.
Autodesk Fusion combines PCB design and mechanical CAD in one app. Core layout is capable, but advanced board features are limited and its signal integrity extension is discontinued.
Professional PCB Design
Complete PCB Design Environment
Yes – the full Altium Designer toolset: schematic capture, PCB layout, mixed-signal SPICE, high-speed routing, rigid-flex, multi-board, and harness design in one editor, with constraint-driven DRC and real-time 3D.
Partial – covers schematic capture, PCB layout, basic ngspice SPICE, and native 3D in one product, with constraint-driven DRC. Rigid-flex, multi-board system design, and harness/cable design are not available.
Interactive & High-Speed Routing
Yes – push-and-shove routing, ActiveRoute, differential pairs, and xSignals length tuning, with impedance-controlled routing driven by an integrated field solver in the layer stack manager.
Partial – push-and-shove, QuickRoute group routing, differential pairs with meander tuning. Impedance control relies on manual calculation from stackup values; the Ansys-powered Signal Integrity Extension is discontinued (EOL March 27, 2026) with no replacement.
Advanced Layer Stackups, Vias & HDI
Yes – unlimited signal layers with a stackup manager that includes material libraries and impedance profiles; full HDI support with microvias, blind/buried vias, and via-stack planning.
Partial – up to 64 copper layers with an upgraded layer stack manager; blind, buried, and micro vias are supported, but there is no impedance field solver or dedicated HDI via-span planning.
Rigid-Flex & Multi-Board Design
Yes – native rigid-flex with bending simulation in 3D, plus multi-board projects with system-level connectivity checks between boards.
No – rigid-flex is not supported; Autodesk's documented workaround is manually bending a 3D PCB and re-importing a STEP file. There is no multi-board system design.
Mixed-Signal Circuit Simulation
Yes – integrated mixed-signal SPICE simulation inside the schematic editor, with modern analysis dashboards.
Partial – an ngspice-based simulator (transient, DC/AC sweep, operating point) is included, but Autodesk support describes it as untouched since its EAGLE-era implementation.
ECAD-MCAD Co-Design
Partial – MCAD CoDesigner provides bi-directional sync with SOLIDWORKS, PTC Creo, Inventor, Fusion, and Siemens NX, including copper geometry and keep-outs. Rigid-flex MCAD sync and MCAD-driven placement are available in Altium Agile.
Partial – Fusion's headline strength is native ECAD-MCAD in a single application. The 3D PCB exchange is effectively one-directional, and there is no live link out to SOLIDWORKS, Creo, or NX.
Component Libraries & Part Intelligence
Live Part Data While You Design
Yes – verified specifications, real-time pricing, stock, and lifecycle intelligence from Octopart and IHS Markit surfaced directly in the design editor. SiliconExpert and Z2Data extensions are available.
Partial – no native part-data feed; supply and lifecycle data comes through the free third-party Avnet add-in. Official library content integrations are SnapEDA and Ultra Librarian.
Unified Component Management
Partial – a unified component model with symbols, footprints, supplier links, 3D models, and where-used tracking. Lifecycle states and templates are available in Altium Agile.
Partial – cloud-managed (Library.io) libraries with symbols, footprints, 3D models, and supplier links, plus IPC footprint generators, but no managed lifecycle-state model, and managed libraries are mandatory.
Design Data Management
Design History & Version Control
Visual Design Comparison Across Schematics, PCBs, Gerbers & BOMs
Reusable Circuit Design Blocks
Yes – proven schematic-plus-layout blocks are stored and reused across projects from a managed library.
No – EAGLE design blocks can be inserted but cannot be created natively in Fusion; reuse requires a round-trip through legacy EAGLE.
Manufacturing Handoff
Complete Fabrication Outputs
Yes – Gerber, ODB++, IPC-2581, NC drill, pick-and-place, BOM, and assembly drawings generated from a controlled release process.
Partial – Gerber RS-274X, ODB++, NC drill, pick-and-place, BOM, and PCB drawings are generated, but IPC-2581 is not supported.
Sharing Version-Controlled Release Packages in Browser
Yes – release packages are stored with version control; manufacturers view and comment via a browser link, with feedback tied back to the project.
Partial – releases can be version-managed in the cloud, but there is no manufacturing-specific, browser-viewable release package with feedback tied back to the design.
Cloud Connected Workflows
Design Review & Team Collaboration (optional)
Partial – browser-based design reviews with comment threads and real-time feedback capture, included with every Develop seat. Checklist-driven reviews with audit-ready logs are available with Altium Agile.
Partial – the general Fusion web client supports comments, markups, and share links, but there is no electronics-specific managed review surface.
Assembly & Contract Manufacturing (optional)
Yes – Assembly Assistant provides a paperless, web-based assembly interface, and in-platform quoting, manufacturability checks, and ordering are available through Altium's vetted CM network.
No – no assembly-instruction tool and no in-platform manufacturing marketplace; prototype part ordering exists only via the Avnet add-in.
Requirements & Managed Workflows (optional, Altium Agile)
No – requirements management, traceability, configurable workflows, and PLM connectors are available within Altium Agile for teams that need them.

About Altium
Altium, headquartered in San Diego, California, is a global software company accelerating the pace of electronics innovation. Altium manages the entire electronics lifecycle and connects all stakeholders throughout the creation process, enabling faster development of electronics-based products for companies of all sizes.
Which Is Better: Altium Develop or Autodesk Fusion®?
Which is better depends on where your product development stops and where your mechanical team works.
Autodesk Fusion genuinely unifies electronics and mechanical design in one application, at a price that makes it a natural starting point for individual engineers and small teams. For a board of moderate complexity that lives within a Fusion mechanical project, it is a good fit. The differences appear when the board becomes more complex and the electronics workflow has to extend reliably from design through release and manufacturing. With Altium Develop:
- Rigid-flex, multi-board, and harness design are built in. In Fusion, these are not available.
- MCAD CoDesigner syncs bi-directionally with SOLIDWORKS, Creo, Inventor, NX, and Fusion itself, so mechanical teams can keep the tools they already use.
- Live component pricing, stock, and lifecycle data from Octopart and IHS Markit are embedded in every BOM, with no add-in required.
- Release packages are version-controlled and shared with manufacturers in a browser, with quoting and ordering through Altium’s vetted CM network.
To cover the same ground, Fusion relies on third-party add-ins where available. Develop extends further into review, sourcing, release, and manufacturing, while additional structured workflows are available through Altium Agile Teams.
If the PCB is one component within a Fusion mechanical project, Fusion is a sensible choice. If PCB design is the center of the job—and the work must carry cleanly through sourcing, review, release, and manufacturing—Altium Develop is built for that workflow.
Switching from Autodesk Fusion® to Altium Develop?
Altium gives Autodesk Fusion users a supported migration path into Altium Develop, and it’s easier and faster than you might think. Fusion exports electronics designs in EAGLE-compatible format, and Altium Designer, included in every Develop subscription, converts those schematics, boards, and libraries into Altium’s file format in minutes.
Your team keeps working from day one, supported by free online training, documentation, and an active user community. And MCAD CoDesigner keeps Fusion in the picture on the mechanical side, syncing board and enclosure changes while your electronics move to Altium.
