Convert STEP to DAE Online
Convert STEP to DAE in seconds. STEP is the ISO 10303 CAD exchange standard; DAE (COLLADA)'s strength is this: a well-established standard still required by some legacy AR/asset pipelines. No software installation required — everything runs in your browser.

Why Convert STEP to DAE?
DAE (COLLADA) is an XML-based scene-exchange format, built around carrying hierarchy, transforms, and animation between 3D applications. Converting from STEP — built around exact engineering geometry exchange between CAD systems and manufacturers instead — closes that gap.
The short version: STEP is optimized for exact engineering geometry exchange between CAD systems and manufacturers, DAE (COLLADA) is optimized for carrying hierarchy, transforms, and animation between 3D applications, and this converter exists for the moment those two needs don't line up.
STEP is the ISO 10303 CAD exchange standard, commonly used for exact engineering geometry exchange between CAD systems and manufacturers. That focus comes with a real limitation: not readable by mesh-only tools like slicers without conversion. DAE (COLLADA) doesn't share that problem — its strength: a well-established standard still required by some legacy AR/asset pipelines.
How to Convert STEP to DAE
- Upload your STEP file.
- MiConvert converts it to DAE, aiming to preserve what makes DAE (COLLADA) useful: a well-established standard still required by some legacy AR/asset pipelines.
- Download the converted DAE file.
- Use it directly with various DCC tools and older AR platforms.
Key Conversion Features
- Produces output ready for various DCC tools and older AR platforms, picking up right where SolidWorks, Fusion 360, Inventor, CATIA left off
- Understands that STEP is the ISO 10303 CAD exchange standard and DAE is an XML-based scene-exchange format, rather than treating the conversion as a blind format swap
- Keeps the parts of your file that matter for carrying hierarchy, transforms, and animation between 3D applications intact, even though the source was built for exact engineering geometry exchange between CAD systems and manufacturers
- Free for files up to 50MB, 100MB for registered accounts
- No local software installation required for either side — not SolidWorks, Fusion 360, Inventor, CATIA, not various DCC tools and older AR platforms — everything runs in the cloud

Frequently Asked Questions
Can I convert the file back from DAE to STEP afterward?
Only what DAE (COLLADA) actually carries can come back — anything specific to STEP's role in exact engineering geometry exchange between CAD systems and manufacturers that didn't survive the original conversion won't reappear.
Why does DAE exist as a separate format instead of everyone just using STEP?
Because they're built for different jobs — STEP is aimed at exact engineering geometry exchange between CAD systems and manufacturers, while DAE (COLLADA) is aimed at carrying hierarchy, transforms, and animation between 3D applications. Neither format is "better," they just fit different parts of a workflow.
What happens to features specific to STEP that DAE doesn't have?
STEP's real strength — true B-rep geometry — exact surfaces and curves, not an approximation — has no equivalent once converted, since DAE (COLLADA)'s constraint is: largely superseded by glTF for new web and real-time pipelines.
Is DAE objectively better than STEP?
Not objectively — DAE (COLLADA) is better specifically for carrying hierarchy, transforms, and animation between 3D applications. For exact engineering geometry exchange between CAD systems and manufacturers, STEP is still the right tool; that's exactly why both formats exist.
What's the real difference between STEP and DAE?
STEP is built around exact engineering geometry exchange between CAD systems and manufacturers (the ISO 10303 CAD exchange standard). DAE (COLLADA) is built around carrying hierarchy, transforms, and animation between 3D applications instead (an XML-based scene-exchange format) — different enough that this is a genuine format conversion, not just a rename.
