STEP and STP files explained
Why CAD exchange needs a specialized parser and viewer.
What matters
STEP and STP are two extensions for the same ISO 10303 family. Unlike STL, a STEP file may retain CAD topology and assemblies. Reliable browser viewing needs a capable parser, a compatible license and performance tests, so LUNA SPACE does not publish an unverified viewer.
A safe workflow
- Keep the source unchanged.
- Test on a representative copy.
- Review the output for meaning, not only file size or a green status.
- Record the settings that worked.
Common mistake
Automation can make a wrong assumption repeat faster. Confirm encoding, units, schema meaning or visual quality before applying a result broadly.
