SOLIDWORKS Partner Program is changing

TL;DR: All software that uses the SOLIDWORKS API or Document Manager (DocMgr) will owe royalties under a new agreement. Hardware and Advocacy partners don’t pay royalties. Non-signers enter a two-year wind-down.

What’s changing:

  • New agreement goes live for online signing in Aug 2025; deadline to sign is Nov 1, 2025; program begins Jan 1, 2026.
  • Royalties apply to any software product that uses SOLIDWORKS API or DocMgr (covers CAD, PDM, Simulation, DraftSight, etc.).
    • No royalties for Hardware and Advocacy partners.
  • Scope across DS products: partner solutions tied to SOLIDWORKS and 3DEXPERIENCE SOLIDWORKS are covered by the same agreement (no separate addendum). Native 3DEXPERIENCE platform apps (e.g., xDesign) remain under CAA.

Exempt from Royalties

  1. Time-limited trials, evaluation, or demonstration licenses
    • Provided free of charge for prospective customer testing.
    • Not renewed or extended for the same user.
    • Royalties apply only if the trial is converted to a paid license.
  2. Free academic licenses
    • Provided at no cost to qualified students, teachers, educators, or faculty.
    • For non-commercial educational purposes.
  3. Non-commercial use licenses
    • Provided free of charge for verified non-commercial purposes.
    • Example: a project for public benefit (“for good”) unrelated to any paid offering.
  4. Freemium versions
    • Limited-functionality or entry-level versions at no charge.
    • Option to upgrade to a paid version or purchase add-ons.

And what is your reaction?

Hi Amen,

What is the source of this text? The letter send out to all partners? Is this an official statement from SOLIDWORKS on their website?

I recently received a document manager Key for 2026 and none of this was stated in their reply…

This can indeed influence future business decisions. Probably the EULA of Future versions are going to change?

Hi all,

does this mean that open source projects like SolidDNA an xCAD must become closed source and commercial?

How do you deal with it?

  1. To be listed as a partner add-in maker, I should start some kind of procedure with Dassault, correct?

  2. What if you sell your add-ins under the radar? I mean, you could deal directly with your customer.
