DirectX model to STEP CAD (ISO 10303)

Convert X to STEP

Drop a .x file to see it in 3D, pick the elements you need and export them as .step. The model stays in your browser.

Drop a model here STEP, IFC, Rhino, FBX, OBJ, STL, 3MF, glTF, DXF, SVG and 50+ more. Include the .bin, .mtl and textures that go with it.
  • Private. Models open in your browser and are never uploaded.
  • Pick elements. Tick walls, doors or any category and export only those.
  • Keeps the data. Names, categories and BIM properties travel with the geometry.

How to convert X to STEP

  1. Open the X file. Drop your .x file on this page. It opens in 3D in your browser.
  2. Pick what you need. Tick the elements or categories you want to keep. You can move, rotate, scale or recolour them first.
  3. Export STEP. Choose STEP (.step) in the export list and press Export. The STEP holds surface bodies made of flat facets, one per element, in millimetres. It is good for reference and fit checks, not for editing features.

X. .x is the old DirectX model format from games and early 3D tools.

STEP. STEP is the exchange format of engineering CAD: SolidWorks, Fusion, Inventor, CATIA, Onshape and FreeCAD.

Questions

How do I convert X to STEP?

Drop the .x file on this page, tick the parts you want, choose STEP in the export list and press Export. The .step file downloads to your computer.

What does the STEP file keep?

It keeps geometry (faceted surfaces), colours and element names. STEP has no place for categories and properties, so those are left out.

How do I open the STEP file?

In Fusion use File › Open. In SolidWorks use File › Open. In FreeCAD use File › Import.

Where do I get a X file?

Older game tools and model packs ship .x files.

Is the X to STEP converter free?

Opening, viewing and editing are free. Your first export is free with a free account. After that, Pro is $5 a month or $39 a year for unlimited exports.

Are my files uploaded?

No. The model is read and converted inside your browser tab. It is never sent to a server, and closing the tab clears it.

What do you need it for?

Over 50 formats open here. Find your use, drop the file, and export what the next program wants.

3D printing
