How do I turn shadows off in SolidWorks?

You can turn off shadows in SolidWorks through the options menu. Here's how:

1. Click Tools > Options.
2. On the General tab, look under the Appearance section.
3. Uncheck the box next to "Display shadows".
4. Click OK.

This will disable shadows in your SolidWorks display, potentially improving performance, especially on less powerful hardware. Keep in mind that turning off shadows is a visual setting and does not affect the actual geometry of your parts or assemblies.
