STEP to PLY Converter
Convert STEP to PLY directly in your browser, then inspect and download the result. STEP / STP input is tessellated to a mesh. Assembly semantics, CAD history and source materials are not retained in this workflow. Static geometry with supported vertex colors. No texture images, scene hierarchy, rigging or animation.

About STEP to PLY conversion
STEP / STP input is tessellated to a mesh. Assembly semantics, CAD history and source materials are not retained in this workflow. Static geometry with supported vertex colors. No texture images, scene hierarchy, rigging or animation.
Conversion quality
CAD and mesh formats describe geometry differently. This workflow may tessellate CAD or create faceted geometry; it does not restore feature history, constraints or assembly intelligence.

What is preserved when converting STEP to PLY?
STEP / STP input is tessellated to a mesh. Assembly semantics, CAD history and source materials are not retained in this workflow. Static geometry with supported vertex colors. No texture images, scene hierarchy, rigging or animation.
When is PLY the right output format?
Choose this mesh output for broad compatibility with viewers, game engines and downstream mesh tools.
What should I check after converting STEP to PLY?
CAD and mesh formats describe geometry differently. This workflow may tessellate CAD or create faceted geometry; it does not restore feature history, constraints or assembly intelligence. Open the downloaded file in the application you plan to use. Check scale, orientation, mesh completeness and the format-specific limits described above before printing, manufacturing or production use.
Where is my model processed?
Available converters process files in your browser. Saving to the workspace stores a GLB copy in this browser's local database; clearing site data removes it.
