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

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

The USDZ file is a format mostly used for interactive 3D, on the Web and elsewhere (e.g., in XR).
The SolidWorks file is a format mostly used for Professional 3D CAD software for mechanical design and product development.

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

USDZ Feature (not supported by SolidWorks)	Limitation Details
Multiple UV Channels	Multiple UV Channels: supported in USDZ, but not in SolidWorks. Multiple UV channels allow the optimized and sophisticated use of various 3D modeling features at once. For example, one can use one set of UVs and 2D texture data to model a tiling texture or procedural material, and another UV set to leverage a global lightmap or occlusion map of the 3D model. In this example, a combination of tiled texture (UV channel 1) and baked ambient occlusion map (UV channel 2) is used. Without support for this feature, one needs to either give up the tiling property (e.g., by using a tool like RapidPipline to bake a single texture atlas), or give up the ambient occlusion map, as only one UV channel will be usable.
Procedural Textures	Procedural Textures: supported in USDZ, but not in SolidWorks. Procedural texture allow the modeling of surface details through mathematical functions, along with artistic control over various parameters. Typically, they are used for patterns like wood grain or other semi-regular structures. Since they are not using any pixels as source data, procedural textures have, in principle, infinite resolution and are very lightweight to describe. In this example, a procedural texture is used to model the look of a wooden material. Without support for this feature, in this case, the wooden parts won't show any visible details.
Normal Mapping	Normal Mapping: supported in USDZ, but not in SolidWorks. Normal maps are used to model shading differences that are arising from small geometric details on a surface, such as fabric structures, visible gaps between bricks forming a wall, or rough rock surfaces. In this example, a normal map is used to model a fabric structure. Without support for this feature, the rendered fabric will look smoother than it actually is in the real world, as the fabric structure won't be visible.
Vertex Colors	Vertex Colors: supported in USDZ, but not in SolidWorks. Vertex colors allow the attachment of colors to each vertex of a 3D model. This can be useful in scenarios such as scientific visualization, or when converting/meshing data from a colored 3D point cloud, for example. On the polygonal surface connecting the vertices, the respective vertex colors are usually smoothly interpolated. In this example, different colors are attached to the different corners of a cube. Without support for this feature, the cube won't have any colors.
Skinned Animations	Skinned Animations: supported in USDZ, but not in SolidWorks. Skinned animations are commonly used for 3D character models in interactive applications, such as games or virtual worlds. They make it possible to easily animate the 3D model using a helper structure based on virtual bones, composing a virtual skeleton for animation control. In this example, a skinned animation is used to pose a 3D character. Without support for skinned animations, the 3D model will remain in its default pose, such as the default T-pose.
Morph Targets	Morph Targets: supported in USDZ, but not in SolidWorks. Morph Targets, or "Blend Shapes", are commonly used to animate facial expressions and soft surfaces, for example cloth under a cloth simulation. They model various states of the animations with different vertex positions. In contrast to skinned animations, morph targets do not use any virtual bones, but work solely on the vertex data. In this example, a facial animation is achieved through morph targets. Without suport for this feature, in this example, the face will not show the animation.
Standardized Format	Standardized Format: supported in USDZ, 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.

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 USDZ 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).
