The available options on the Set CAD Options page depend on the type of CAD file you imported on the Load Design Files page because each CAD file format has different options for importing. (For example, you can import mirrored pads, bottom-looking rotations, BOM data, local fiducials, and so on.)
In most cases, we recommend you accept the default options when importing CAD files. On occasion, if bottom side parts don't look correct, you may want to try different import options on the Set CAD Options page until they look correct.
