### COPALIGN Command Mode Text

The COPALIGN command allows you to align clouds of points with your CAD data.

F1=COPALIGN/REFINE = n1,n2,n3,n4 SHOWALLPARAMS=TOG1

ROUGH ALIGNPAIR/

THEO/x,y,z,i,j,k

MEAS/x1,y1,z1

REF,TOG2,

n1 represents the total number of sample points to use in the refinement.

n2 represents the maximum number of iterations.

n3 represents the convergence threshold.

n4 represents the offset value for applying a thickness.

TOG1 lets you show or hide the parameters used for the rough alignment. It can be set to YES or NO.

ROUGH ALIGNPAIR/

THEO/x,y,z,i,j,k,

MEAS/x1,y1,z1

These rough alignment pairs of points are defined/selected using the Graphics Display window. The values next to THEO/ represent the point on CAD. The values next to MEAS/ represent the corresponding point on the cloud of points. These pairs are used to determine a rough transformation between CAD and the pointcloud which will allow the cloud of points to come close enough to CAD to allow further refinements of the alignment.

TOG2 lets you choose the pointcloud to use for the alignment.
