The short version

  • Only Fusion 360 has a free tier, so it costs nothing to try first.
  • Each has a real cost: Fusion 360 requires paid subscription for professional use; Siemens WinCC Unified licensing counts PowerTags, and archived tags are licensed separately from displayed tags, so a project that adds historian logging late can breach a tier and trigger an unbudgeted step-up purchase.
  • They diverge on capability: Fusion 360 covers 3D CAD modeling, Siemens WinCC Unified covers TIA Portal engineering.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Fusion 360

  • Requires paid subscription for professional use
  • Cloud-based, requires internet connection
  • Free tier limited to students and educators

Siemens WinCC Unified

  • Licensing counts PowerTags, and archived tags are licensed separately from displayed tags, so a project that adds historian logging late can breach a tier and trigger an unbudgeted step-up purchase.
  • There is no migration tool that converts a WinCC V7 project to Unified, so leaving the classic line before its 2027 support end means rebuilding screens, scripts and alarm configuration by hand.
  • Scripting moved from VBScript to JavaScript, which invalidates the script libraries in-house engineers accumulated over a decade on classic WinCC.
  • It is effectively bound to the Siemens controller stack; connecting Rockwell or Mitsubishi PLCs works through OPC UA but loses the shared tag database that is the main reason to buy it.
  • Three unrelated products share the WinCC name, and buyers who specify WinCC without saying Unified, V7 or OA regularly receive quotes for the wrong platform with different licensing and a different contractor pool.

Source
Siemens WinCC Unified: Is WinCC OA the same product?

No. WinCC OA came from ETM, has its own engineering environment and licensing, and is aimed at very large distributed systems. It shares only the brand.

Fusion 360: Does Fusion 360 support 3D modeling, CAD, and CAM?

Yes. Fusion 360 is a cloud-based platform that integrates 3D modeling, CAD, CAM, CAE (simulation), and PCB design in one software.

Source
Siemens WinCC Unified: What is a PowerTag?

An externally connected process variable in the runtime. Internal tags do not count, but archived tags are licensed separately from displayed ones.

Siemens WinCC Unified: Can operators use it from a browser without installing anything?

Yes, the runtime is HTML5, but concurrent browser clients need WebUX or Unified client licences.
