Learn how to import and export STEP files in Shapr3D, including supported CAD geometry, export settings, and compatibility considerations.
What is a STEP file?
STEP (Standard for the Exchange of Product Model Data) is a widely used CAD file format for exchanging 3D models between different CAD applications.
Unlike mesh formats such as STL, STEP files can represent precise solid and surface geometry, making them useful for transferring models between CAD systems and manufacturing workflows.
Import STEP files into Shapr3D
Shapr3D supports importing STEP files containing 3D CAD geometry. Imported geometry can be used in your designs and modified using Shapr3D's modeling tools.

Export STEP files from Shapr3D
Export your Shapr3D designs in STEP format to exchange precise CAD geometry with other supported applications.
STEP output format
The Output Format setting lets you choose the STEP application protocol used for the exported file.
The available protocols include:
- AP203: An established STEP protocol for exchanging 3D mechanical CAD geometry.
- AP214: A STEP protocol commonly used for exchanging automotive and mechanical design data.
- AP242: A newer STEP protocol designed for model-based engineering and CAD interoperability.
Additional export settings
You can also configure the following settings:
- File Name: Enter a name for the exported STEP file.
- Include Hidden Items: Include hidden items in the export.
- Save Each 1st-Level Item Separately: Export first-level items as separate files, with file names based on their item labels.

Considerations when using STEP files
CAD geometry
STEP is suitable for exchanging precise 3D geometry between CAD applications. Unlike Shapr3D's native .shapr format, STEP does not preserve Shapr3D's parametric design history.
Application compatibility
Different CAD applications may support different STEP application protocols. If your destination application requires a specific protocol, select the corresponding option under Output Format.
