UV Scan Settings area
The UV Scan Settings area in the scan dialog box (Insert | Scan) enables you to define your UV scan. It contains the U and V rows and allows you to define the following controls.
The Hits values allow you to specify how many hits the scan will take on the surface in the U or V direction.
The Start and End values allow positioning of the hit matrix on the surface that is being scanned. These values can be set for both the U and V rows and apply to the scan along the U and V axes. Note that UV space uses numbers between 0.0 and 1.0 to represent the entire surface. So 0.0, 0.0 will be on the opposite diagonal corner from 1.0, 1.0.
The non-editable Position fields indicate the probe 's current position along the U and V axes.
