Saved in SolidWorks 2024–2026? SolidWorks 2023 opens a STEP of it as a solid body, usually on the part's own surfaces. SolidWorks 2023 is the first release out of reach of a 2026 seat; only a 2024 or 2025 seat can still save back to it.

ResultSTEP (usually exact)

A STEP of the part — usually its own surfaces, planes, cylinders, cones and splines as modelled — that SolidWorks 2023 opens directly as a solid body. Native SolidWorks 2023 files are coming.

No feature tree: the finished shape, not the steps. Exact whenever the part's solid can be read; otherwise its surfaces are rebuilt from the part's display mesh.

  • Future Version — from 2023 SP5, a 2024 part opens read-only: measure it, not edit it.
  • Save As previous version — from 2024 or 2025, with features intact; needs that seat and an active subscription, and refuses features new to it.
  • Here — no SolidWorks and nobody else: a STEP today, a native 2023 part when it is ready.
Your fileWhich release saved it
  1. In Windows File Explorer, right-click the part, then Properties and Details: SW Last saved with names the release.
  2. For a folder of parts, add SW Last saved with as a column in the Details view.
  3. Or drop it above. The converter reads it and says Saved in SolidWorks 2026, or that it already opens in 2023.

Some tools show an internal number instead: SolidWorks 2023 is 16000.

Questions7 answered
Can SolidWorks 2023 open a file from a newer version?
Only a 2024 part, read-only, from 2023 SP5 on. A part saved in 2025 or 2026 is refused.
How do I convert a SolidWorks 2026 part to 2023?
Native 2023 files are not available yet. Convert it to STEP above, then open the STEP in SolidWorks 2023: it arrives as a solid body, usually on the part's own surfaces.
Can't SolidWorks' own Save As do it?
From SolidWorks 2024 or 2025 only, with that seat and an active subscription. It keeps features, but refuses a part that uses one new to that release. A 2026 seat cannot reach 2023.
Is the feature tree kept?
No. You get the finished shape as an imported solid — planes, cylinders, cones and splines exact — not the features that built it.
What is SolidWorks version 16000?
SolidWorks 2023. Some tools show a release as an internal number that rises by 1000 a year, so 2026 is 19000.
Does it work for assemblies?
Not yet — parts only. An assembly holds no part geometry: each part is its own file, and each can be converted here.
Is it free?
Yes to start: 2 solid-geometry conversions a day with no account, and 4 a day with a free one; past that each costs 4 credits, and Maker includes them. Checking which release saved a part is free.
