Parasolid exchange is often a text .x_t file. Several mechanical CAD systems can write it, including workflows that start in Solid Edge or NX, but the extension is not a guarantee of which application or which schema version you received. CADProps reads text X_T and can convert supported X_T geometry to STEP. Binary .x_b is not enabled. Renaming X_B to X_T does not change the encoding.
Open X_T
Use the Parasolid viewer on the original file. Check the expected bodies, orientation and one known dimension before area, volume or mass. Open an X_T file online is the full sequence.
Volume is for a valid closed solid. Mass is volume times a density you confirm. An assembly or a partial load must be labelled with its scope.
Convert to STEP
Parasolid to STEP is the validated output when the recipient wants a neutral file. It does not restore a feature tree. Reopen the STEP and repeat the dimension check. Parasolid vs STEP and IGES vs Parasolid explain when to stay with X_T.
Native files that are not X_T
Solid Edge .par, .psm and .asm files are not opened here. Ask for X_T or STEP, as described in open a Solid Edge file. Creo .prt is not this Parasolid path and is not the NX PRT path either.
The format matrix lists X_B, SAB and other formats that remain disabled.
