#### Clean COPOPER

Pointcloud Operator dialog box - Clean Operator

This operation is used to eliminate outliers by using the distance of the points to the CAD model of the part. If the distance of a point is greater than the value of MAX DISTANCE the point is considered an outlier or not belonging to the part. To use this operation, you must have at least a rough alignment established (see "Rough Alignment").

Applying the Clean operation to a Pointcloud can be done by clicking the Clean Pointcloud button from the Pointcloud toolbar or by selecting the Operation | Pointcloud | Clean menu item.

The Clean Operator uses the following option:

- Max Distance – Indicates the maximum distance of a point to the CAD model for which the point is considered an outlier.

- CAD Controls - Marking Select in this area and lets you select the surfaces in the Graphics Display window around which the clean operation is based. Selected surfaces will be highlighted in red. The operation affects the entire cloud of points with respect to the selected surfaces. Any point that is located at a distance greater than the specified Max distance from all selected surfaces will be discarded. For example, suppose you select a single surface and type a value of 10. This means any points in the COP located 10 or more units away from the selected surface will be cleaned. Any points in the COP within the length of 10 units of the selected surface will remain.

Clicking Create after editing the command inserts a COPOPER/CLEAN command into the Edit Window like the following example:

COPOPER5 =COPOPER/CLEAN,MAX DISTANCE=0.005,SIZE=0
