Iterative alignment transformation matrix

I try to explain, even if it's a little hard for me in english !!!
For the "format" function, it's usefull for 2 things : first, it removes the "<" and ">" of a vector or a point value - second, it allows you to write more values than decimal place does.
For the matrix rotation, if you turn around Z of an angle A, the matrix is wrote like this :
Cos A Sin A 0
-Sin A Cos A 0
0 0 1
If you do another rotation around another axis, you write another matrix like this one, but cos, sin , 0 and 1 change of place.
The total rotation matrix result is the product of the first by the second (etc if there are more rotations).
If you construct a first alignment, for example INIT_REF, then you measure a second alignment (END_REF), you recall init_ref and you assign what I wrote in the first reply.
ASSIGN\V1=FORMAT("%3.3f,%3.3f,%3.3f",END_REF.ORGIN )
ASSIGN\V2=FORMAT("%3.8f,%3.8f,%3.8f",END_REF.XAXIS )
ASSIGN\V3=FORMAT("%3.8f,%3.8f,%3.8f",END_REF.YAXIS )
ASSIGN\V4=FORMAT("%3.8f,%3.8f,%3.8f",END_REF.ZAXIS )

You can create a generic feature point with x = V1.X,Y=V1.Y and Z = V1.Z.
It's the origin of END_REF.
You can create a plane with X=V1.X,Y=V1.Y and Z = V1.Z and I=V4.X,J=V4.Y and K=V4.Z, and create Z axis of END_REF. The same for X and Y planes.
If you write matrix in a text file, you can recall values with read function.
I use it when the init ref is not easily accessible all the long of measurement (after a reversal, for example)

I hope it's clear, I'm not sure !!!!!!
