### Refined Alignment

The Refined Alignment area allows for a more refined alignment to occur. This consists of the following items:

- Type list box - None, Face, Uniform and Random types can be selected to determine how the comparison between the pointcloud and the CAD surfaces is established.

- Face - Plane surfaces are used.

- Uniform - Points with a uniform distribution throughout the point cloud are used

- Random - Randomly selected points are used.

- Num. Points box - Defines the number of pairs of CAD/Pointcloud points to be used for the Refined Alignment of Random and Uniform point types. In case Face type is used, this box shows the number of pairs that have been used in this type of alignment. 6 is the minimum number that can be used.

- Deviation area - This are shows the Average and Maximum deviations between the CAD and Pointcloud pairs after the Refined Alignment is performed.

- Apply executes the alignment.

- Undo resets the alignment.

In order to be able to obtain a good Refined Alignment the pointcloud points should be close enough to the CAD points through the initial rough alignment described above.
