General Information

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

Converting and Optimizing STL Files to SolidWorks

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

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

What are STL and SolidWorks files commonly used for?

The STL file is a format mostly used for 3D printing.
The SolidWorks file is a format mostly used for Professional 3D CAD software for mechanical design and product development.

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 - Textures can be embedded in appearances but with limited format support compared to dedicated 3D graphics formats.
3 - Limited multi-UV support, primarily through appearances and materials for visualization rather than game development workflows.
4 - Basic normal mapping support through SolidWorks Visualize and appearance properties, but not extensively used in typical CAD workflows.
5 - Limited procedural texture capabilities, mainly through basic material properties and appearance settings.

Limitations of STL Files to SolidWorks Conversion Workflow

The following limitations should be taken into account when converting STL files to SolidWorks format:

STL Feature (not supported by SolidWorks)Limitation Details
Standardized FormatStandardized Format illustratedlack of support for Standardized Format illustrated
Standardized Format: supported in STL, but not in SolidWorks.

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.

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

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 STL and SolidWorks 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.
