# X_T to STEP Converter Online: Convert Parasolid Files
Convert Parasolid X_T files to STEP online, inspect the source geometry first, verify units and dimensions, and download the validated neutral CAD result.
Convert a Parasolid X_T or X_B file to STEP without installing a desktop translator. CADProps reads both encodings in-house; units in the file are metres. You get an exact STEP when every face is reconstructed, and a mesh STEP otherwise. View and measure without an account; sign in to convert.
## Inspect the source before converting
Open the Parasolid file first and confirm that the expected solid or bodies are present. Check a known dimension and the model scale. Converting the wrong source file perfectly still produces the wrong deliverable.
## Exact STEP or mesh STEP
Exact STEP keeps surfaces and edges for CAD and CAM. If any face is omitted or approximated, exact STEP is disabled and the Convert dialog offers a mesh STEP, STL, OBJ, 3MF, glTF and GLB built from the preview triangles. A mesh STEP suits review and overall size, not machining features.
## STEP does not carry Parasolid history
The output is intended for neutral geometry exchange. It does not reconstruct sketches, constraints, feature history or application-specific design intent.
## Verify units and overall dimensions
After conversion, compare a known source dimension with the STEP result. A unit mistake can create a plausible-looking model at the wrong physical scale. Record whether the handoff is millimetres, inches or another agreed unit.
## Check bodies and downstream usability
Confirm body count, orientation and any critical holes, pockets or mating surfaces. When the next workflow is CAM, quoting or supplier review, open the STEP in that receiving workflow where practical rather than relying only on a conversion-success message.
## Keep the original Parasolid file
Treat the STEP as a derivative deliverable. Keep the original X_T or X_B unchanged with its revision context so a later conversion can be reproduced or compared if the receiving system reports a problem.
**Input formats:** X_T / X_B
**Points:** viewing and measuring are free. A new account gets 3 free conversion points; free points are valid for 90 days. One point converts one file to every output format for 30 days, and a failed or incomplete conversion uses none. See [pricing](https://www.cadprops.com/pricing/).

General steps for uploading, viewing, sectioning, measuring, converting and exporting are explained once in [How it works](https://www.cadprops.com/how-it-works/index.md). This page covers what is specific to this file type.

## When a result needs another check
Viewing can start without an account. Conversion, account storage and share creation require signing in. Temporary files expire after the displayed retention period. Read the privacy statement for server processing and deletion, and the accuracy notes before using numerical results. Do not assume that hiding a part, clipping it or exploding an assembly changes the exported source geometry.

## Capabilities and limits
- Convert Parasolid X_T files to STEP online, inspect the source geometry first, verify units and dimensions, and download the validated neutral CAD result.
- Exact STEP needs every face reconstructed; otherwise the export is mesh STEP. Native feature history is not preserved.
- Files are uploaded for server processing; support depends on format, version and geometry.
- Viewing and measuring do not require an account. Free conversion points are valid for 90 days. Sign in to convert, save files across devices or create share links.
## Questions about this task
### Can I convert X_T to STEP online?
Yes, for text X_T and binary X_B files. Upload, inspect, sign in and choose STEP. Exact STEP is offered when every face is reconstructed; otherwise a mesh STEP.
### Is X_T the same as X_B?
No. X_T is the text Parasolid form and X_B the binary form. CADProps reads both; renaming one to the other does not change the encoding.
### Will STEP preserve the Parasolid feature tree?
No. STEP is a neutral exchange representation and does not restore the original parametric modeling history.
### How should I verify the converted STEP?
Check units, one known dimension, expected bodies or components, and one or two critical geometric features in the receiving workflow.
### Can I convert a bad or unreadable X_T by renaming it?
No. Renaming the extension does not translate the data. Ask for the original source information or a fresh export.
### Do I need an account to convert files?
View and measure without an account. Register or sign in to convert, save files and create share links. Recipients can view shared models without an account.
