It sounds like you're looking for a tool or method to open future-version SolidWorks files in an older version of the software.
This is a deliberate, architectural decision. SOLIDWORKS file formats are tied to the kernel and feature-recognition logic of their specific versions. Allowing full backwards compatibility would risk geometric corruption, rebuild errors, and instability. solidworks future version file converter link
.SLDPRT), assembly (.SLDASM), or drawing (.SLDDRW) created in a newer release.| Method | How It Works | Best For | |--------|--------------|-----------| | Parasolid Export (.X_T, .X_B) | Exports the exact solid geometry without history. | Sharing precise solid models when feature tree isn't critical. | | STEP/IGES Export | Industry-standard neutral formats. | Interoperability with other CAD systems and older SOLIDWORKS versions. | It sounds like you're looking for a tool

Crucial Warning: Even these third-party tools cannot convert the parametric history. They convert the BREP (Boundary Representation) geometry. You will get a solid body, not a feature tree.
