This guide is part of the RapidPipeline 3D Formats Knowledge Database. It shows how to convert SolidWorks to Rhino 3DM, if you'd like to know more about the formats, please check out the following links:

Converting and Optimizing SolidWorks Files to Rhino 3DM

There are various ways to convert between SolidWorks and Rhino 3DM. With RapidPipeline, you can easily convert and and optimize SolidWorks 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:

What are SolidWorks and Rhino 3DM files commonly used for?

The SolidWorks file is a format mostly used for Professional 3D CAD software for mechanical design and product development.
The Rhino 3DM file is a format mostly used for NURBS-based 3D modeling and design.

0 - Limited vertex color support, mainly through part coloring and appearance assignments rather than per-vertex color data.
1 - SolidWorks uses proprietary file formats, though it supports many industry-standard import/export formats like STEP, IGES, and others.
2 - Proprietary format with open specification (openNURBS)
3 - Textures can be embedded in appearances but with limited format support compared to dedicated 3D graphics formats.
4 - Textures can be embedded in the 3DM file
5 - Limited multi-UV support, primarily through appearances and materials for visualization rather than game development workflows.
6 - Basic normal mapping support through SolidWorks Visualize and appearance properties, but not extensively used in typical CAD workflows.
7 - Limited procedural texture capabilities, mainly through basic material properties and appearance settings.
8 - Basic procedural material support

Limitations of SolidWorks Files to Rhino 3DM Conversion Workflow

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

SolidWorks Feature (not supported by Rhino 3DM)Limitation Details
Animations

Animations Support:

SolidWorks: Full support | Rhino 3DM: No support

Animations illustratedlack of support for Animations illustrated

Impact:

Animations are an important part of many interactive 3D assets, for example in real-time rendering (including games, XR training, assembly instructions, product demos, and other use cases). There are various kinds of animations that can be used on 3D models. In this example model, a rigid animation is used to make the gears spin. Without support for this feature, in this example, the gears won't move.

Rigid Animations

Rigid Animations Support:

SolidWorks: Full support | Rhino 3DM: No support

Rigid Animations illustratedlack of support for Rigid Animations illustrated

Impact:

Rigid Animations are typically used to animate mechanical parts. In this example, the door of this 3D model of a microwave can be interactively opened or closed, using a rigid animation that gradually changes the 3D transformation of the door. Without support for this feature, in this example, the door will just stay in place and won't move.

What's the best way to get SolidWorks files into my 3D applications, and are there alternatives to using Rhino 3DM?

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 SolidWorks 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.

Therefore, our expertise will help you to reach your goals faster, at scale, and with the least possible friction, since we are focused on maximum interoperability.
