The Burning Question: Can You Download Sizer 323 for Free?

Here is the short answer: Legally, no. But historically, yes, it was available as a free download from Siemens under specific conditions.

Let us break this down carefully.

The Legal Reality

Siemens Sizer (including version 3.2.3) is proprietary engineering software. While Siemens has always offered "trial" or "free configuration" versions for certain tools, the full functionality was typically tied to a license key or a login with a valid service contract.

However, unlike high-end simulation tools (like NX or Tecnomatix), Sizer has often been positioned as a free engineering aid for customers. Siemens’ official stance over the years has been to provide Sizer as a no-cost download to registered users on their Industry Mall or Support Portal.
