The Complete SolidWorks to COLLADA Conversion Guide.

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

There are various ways to convert between SolidWorks and COLLADA. With RapidPipeline, you can easily convert and and optimize SolidWorks files, at scale. It supports COLLADA, 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 SolidWorks file is a format mostly used for Professional 3D CAD software for mechanical design and product development.
The COLLADA file is a format mostly used for 3D asset exchange for digital content creation.

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

SolidWorks Feature (not supported by COLLADA)	Limitation Details
Free-Form Surfaces	Free-Form Surfaces Support: SolidWorks: Full support | COLLADA: Partial support COLLADA Notes: Limited NURBS support, primarily polygonal Impact: Free-form surfaces allow a CAD user to design surfaces with advanced controls over curvature and continuitiy. While these surfaces are common for CAD models (in the form of so-called boundary representations or "B-reps"), they need to be converted to polygonal triangle or quad data to work with most 3D rendering engines - a process called tessellation. In this example, a surface patch is used to describe a part of a curved surface of a product. Without support for this feature, the free-form surface has to be tessellated into quads or triangles.
Embedded Textures	Embedded Textures Support: SolidWorks: Partial support | COLLADA: No support SolidWorks Notes: Textures can be embedded in appearances but with limited format support compared to dedicated 3D graphics formats. Impact: Embedded textures allow the storage and exchange of an entire 3D model and its materials within a single file, by embedding the texture images directly into the 3D file (and not storing them as separate image files). Without support for this feature, textures have to be stored in separate image files, and referenced from the main 3D model file.
PBR Materials	PBR Materials Support: SolidWorks: Full support | COLLADA: Partial support COLLADA Notes: Basic PBR support through material extensions Impact: PBR materials enable Physically-Based-Rendering (PBR) for a standardized, photorealistic look of rendered images. PBR uses concepts like metallic-roughness or specular-glossiness properties and a microfacet-based modeling of the surface, using a concept called BRDF (Bi-Directional Reflectance Distribution Function). In this example, PBR materials are used to achieve realistic looking plastic and metal materials. Without support for PBR materials, only basic colors and shading can be used (for example, based on more simple shading models, such as the Blinn/Phong model).

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 COLLADA 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.
