[ADVANCED\]UV_PREVIEW [Key Value [...]] /FILE FileIn [Drop] [/BROWSE Ataper] Without /FILE, UV_PREVIEW works from the current UV data set. With the /FILE option, it will pre-view the UV data set from the speci- fied file.

The default drop is 5% of bandwidth on each side, but can be changed with the option Drop value (in %).
