There are various ways to convert between STEP Enhanced and Rhino 3DM. With RapidPipeline, you can easily convert and and optimize STEP Enhanced files, at scale. It supports Rhino 3DM, as well as many other file formats (examples: FBX, glTF, OBJ, PLY, STL, USD, USDZ, VRM), at high quality.

Below you can find a video explaining how to convert your files:

The STEP Enhanced file is a format mostly used for product data exchange for manufacturing.
The Rhino 3DM file is a format mostly used for NURBS-based 3D modeling and design.

The following limitations should be taken into account when converting STEP Enhanced files to Rhino 3DM format:

STEP Enhanced Feature (not supported by Rhino 3DM)	Limitation Details
Geometry Compression	Geometry Compression Support: STEP Enhanced: Partial support | Rhino 3DM: No support STEP Enhanced Notes: Compressed formats (.stpz, .stpxz) available for smaller file sizes Impact: Geometry compression describes the process of compressing the representations of a 3D model's geometry, usually a triangle mesh. 3D geometry compression does not change the topology of a 3D model, but just changes the way that a 3D model and its 3D positions and related vertex data is stored. Geometry compression can be lossy (just like JPEG compression in image processing can be lossy, for example), in which case one might notice slight artifacts like variations in 3D vertex positions (compared to the uncompressed 3D model). However, such differences are often not noticeable. There are only very few standards for geometry compression, like glTF's support of Draco compression and similar extensions.
Standardized Format	Standardized Format Support: STEP Enhanced: Full support | Rhino 3DM: Partial support Rhino 3DM Notes: Proprietary format with open specification (openNURBS) Impact: Standardization plays a huge role in 3D model formats. With a format being standardized, every application will have a clear way of how to load or store data using this format. This makes it easier to re-use the 3D model across different applications, but also to make sure it will still be accessible and usable after a couple of years.

Doing 3D conversion right, especially at scale, can be tricky, as 3D data is in general a rather complex (yet very powerful!) medium. This also applies to STEP Enhanced and Rhino 3DM files - the conversion guide above provides a rough first idea about that. Once you know what you would like to do, tools like RapidPipeline can help you perform the necessary steps, and to even automate the process for thousands or even millions of files.

Especially when introducing pipelines and workflows at scale in an enterprise context, it is usually good to rely on dedicated tools and expertise, making sure you do not introduce any steps into your 3D workflow that are detrimental to the final output's quality, or that take your team too much time (and money).

If you're interested to hire dedicated expertise from the best in the field to help your company reach your goals fast and reliably, please do not hestitate to contact DGG. Being the creators of RapidPipeline, and ambassadors for open 3D standards for more than a decade, we have been building some of the world's most advanced 3D pipelines, having processed many millions of 3D assets.
