Is there a free or low-cost viewer for U3D files exported from SolidWorks? Thanks...

According to U3D File Extension - Open .U3D Files both Blender & DAZ 3D are able to view U3D files, & are free.

blender.org - Home of the Blender project - Free and Open 3D Creation Software

DAZ 3D | Free 3D software and content

The fileinfo.com site either has outdated or incorrect info, as the current Blender and DazStudio don't allow import of U3D.

The only application I found that does open it is Simlab Composer, and while its not free, it is low cost.

A viewer that may work for you is Sketchfab. Looks like they have a plugin for SolidWorks, and they do have free accounts although your usage would determine if a paid account would be  needed. This does not use U3D format.

Hi,

you can embed u3d files into any TeX document.

You'll need:

\usepackage[3D]{movie15}

and the function:

\includemovie[......]

But your question has become obsolote since there is no more support for u3d since 2015.
